"It's waterproof" might be the most abused phrase in the gear world. Phones are "waterproof" until they meet a swimming pool. Jackets are "waterproof" until hour two of real rain. So when a Peli case says IP67, what are you actually allowed to expect: rain, a river crossing, a case sinking off the dock, a dive?
This guide, updated for the 2026/27 season, gives seven straight answers about what IP67 really certifies, where its limits sit, which Peli models carry it, and how to make sure your case still earns its rating five years from now. Autumn storms, winter sea trips and cold-water sessions are exactly when the difference between "water-resistant" and "waterproof" stops being theoretical.
7 Straight Answers About Peli Cases and Water
1. What does IP67 actually certify?
IP ratings come from an international standard, and the two digits mean two separate things. The 6 is dust: completely dust-tight, the highest solid-particle rating there is. The 7 is water: the enclosure withstands temporary immersion, tested at a depth of up to about one metre for around 30 minutes. The Peli Air product pages describe it the same way: submerged to one metre for up to 30 minutes without a drop reaching the contents.
That is a controlled laboratory definition, and it is exactly what it sounds like: your sealed case can fall into water, sit briefly beneath the surface, and come out with dry contents. What IP67 does not certify is continuous submersion, deeper water or pressurised use. Those belong to a different rating class entirely.
2. So: waterproof, water-resistant or submersible?
The vocabulary sorts itself out once you put the three words side by side.
| Term | What it honestly means | Typical example |
|---|---|---|
| Water-resistant | Survives splashes and rain, not immersion | Padded camera bags with coated zips |
| Waterproof (IP67) | Sealed against water ingress in normal use, including temporary immersion | A closed Peli Air case with its O-ring seated |
| Submersible | Prolonged, deliberate underwater use at depth, pressure-rated for the job | A purpose-built dive housing |
A Peli case is emphatically the middle category: genuinely waterproof, and a category above almost every bag on the market, but not a dive housing.
3. Can I dive with it?
No, and it is worth understanding why rather than just taking the rule. Water pressure grows rapidly with depth, loading the lid and seal far beyond what the immersion test represents. A case taken diving may survive (people post such stories), but you would be operating outside the rating, on luck rather than engineering.
If your camera needs to work underwater, buy a purpose-built dive housing and let the Peli do what it is certified for: getting the gear to the water dry, and surviving the accident where it falls in. If you are planning a first course this season, our first dive course checklist shows which small items belong in a sealed case on the boat.
4. What do the O-ring and that little valve actually do?
Two components carry the whole waterproof promise. The O-ring, a continuous gasket seated around the lid rim, compresses when the latches close and creates the watertight barrier. Everything depends on it being clean, undamaged and properly seated.
The automatic pressure equalisation valve solves a subtler problem. Altitude and temperature changes create pressure differences that could vacuum-lock a sealed case shut (ever fought a lid after a flight?). The valve lets air through a membrane that blocks water: pressure equalises, water stays out. It is clever, invisible and essential, so do not paint over it, block it or "upgrade" it. If a lid ever refuses to open, read why a Peli case will not open and what the pressure valve is doing before you reach for a screwdriver.
5. What real scenarios does IP67 comfortably cover?
Translated into life, the pattern is simple: IP67 covers incidents, not underwater missions.
- Yes: torrential rain for hours, and an autumn storm on a roof rack.
- Yes: sea spray across a boat deck all day.
- Yes: a case dropped overboard at the dock and fished out a few minutes later, which is nearly the textbook test.
- Yes: standing in a puddle, buried in wet snow, or briefly under water during a river crossing.
- No: sinking in deep water beyond reach, or hours submerged.
- No: towing the case behind a kayak as cargo.
Sailors should also read what survives a capsize, which sorts boat gear into what a sealed case protects and what needs another solution.
6. What silently kills waterproofing?
Almost every "my case leaked" story traces back to one of five causes.
- Grit on the seal. A sand grain or hair across the O-ring: the seal is only as good as its cleanest millimetre.
- A tired O-ring. A damaged, twisted or ageing ring nobody ever inspected.
- Half-closed latches. Half-latched is not sealed.
- A deformed lid rim. Cracks or distortion after severe abuse.
- Salt. Dried salt crystals abrade seals and corrode hardware, so a saltwater life without freshwater rinses shortens everything.
None of these is a design flaw. They are maintenance items, which is good news, because maintenance is free. Hardware wear is covered separately in 11 things that wear out on a Peli case.
7. How do I keep (and check) the rating for years?
A five-minute ritual a few times a year is enough:
- Open the case, run a finger around the O-ring feeling for nicks or flat spots, wipe the ring and its groove clean, and reseat it evenly.
- After saltwater exposure, rinse the closed case with fresh water and let it dry before opening.
- Inspect the valve area for paint, stickers or grime.
- If the O-ring ever looks tired, replace it. The Peli Protector page describes the perimeter O-ring as replaceable, and a fresh seal restores the case to factory waterproofing.
- Before an important trip, latch the empty case and give it a shallow bath in the tub. A paper towel inside will report any failure honestly.
At the end of the season, do the same check before you put the case away, so it is ready the first time you need it next year.
Which Peli Case for Which Water Job
All the cases below share the same basic sealing idea: a continuous O-ring around the lid and an automatic pressure equalisation valve. They differ in size, weight, wheels and how they travel. The Air series is made from HPX² polymer and its product pages state IP67 and MIL-SPEC certification and a weight up to 40% lower than conventional cases of the same class. The Protector models are described as watertight, crushproof and dustproof, with the O-ring seal and valve.
| Model | Format | What the product page says | Best for |
|---|---|---|---|
| Peli 1200 Protector | Compact hand case | Neoprene O-ring seal, five colours, foam or no foam | Action camera, phone, keys and small valuables on a boat or beach |
| Peli 1400 Protector | Compact to mid-size hand case | Pick N Pluck foam, six colours, made in Germany | Mirrorless body with lenses, field instruments, a small drone |
| Peli 1450 Protector | Mid-size hand case | No foam, foam or padded dividers, six colours, made in Germany | Camera kit with swappable lenses, drone and controller |

| Peli Air 1525 | Medium carry-on-friendly case | IP67 and MIL-SPEC, Press and Pull latches, up to 40% lighter | Drone and camera kits that fly in the cabin |
| Peli 1510 Protector | Wheeled carry-on, 56.1 × 35.9 × 22.9 cm outside, 50.2 × 27.9 × 19.3 cm inside | Telescopic handle, polyurethane wheels, three interior options | Travelling to the coast with a full kit and keeping it in the cabin |
| Peli Storm iM2950 | Large wheeled expedition case | Watertight and airtight, Vortex valve, in-line wheels, Black or Odd Green | Off-road and river-crossing expeditions |
| Peli Air 1615 | Large wheeled case for checked baggage | IP67 and MIL-SPEC, quiet-rolling wheels, four interiors, five colours | Flying with dive, camera or drone gear in the hold |
For the exact internal dimensions and weight of each variant, open the product page and check the variant you are buying, because those values change with the interior option.
Compact Cases for Wet Work
Small enough for a day on the water, sealed enough not to care how the day goes. These are the cases that go in a kayak hatch, a boat locker or a rucksack.
Peli 1200 Protector Case
The smallest in this group. It uses a neoprene O-ring and an automatic pressure equalisation valve, and comes in five colours with or without foam. Bright yellow or orange makes it easy to spot on a deck or a pebble beach. It suits action cameras, a compact camera, a phone, keys and documents.
Peli 1400 Protector Case
A step up in size, with a Pick N Pluck foam insert and a convoluted foam pad in the lid. The page lists six colours and German manufacture. A mirrorless body with two lenses fits comfortably, which makes it a common choice for shooting near water.
Peli 1450 Protector Case
Compact enough to slide under an aircraft seat, with three interior choices: no foam, Pick N Pluck foam or padded dividers. The padded dividers version is popular with photographers who swap lenses on location.
Peli Air 1507 IP67 Case
The lightweight option in this group. It is made from HPX² polymer, certified IP67 and MIL-SPEC, and has a fold-down over-molded handle that sits flush when not in use. It has no wheels, so it is designed for people who pick it up and walk.
Bigger Water, Bigger Cases
Heading out with a full camera kit, expedition equipment or a boat's worth of gear? The same sealing idea scales up through the medium and large formats, including wheeled cases built for the wet, sandy, salty end of the outdoors.
Peli Air 1525 Waterproof Case
A medium, carry-on-friendly case that fits a camera body with a couple of lenses or a drone controller with accessories. IP67, MIL-SPEC and up to 40% lighter than comparable cases, which matters when the airline allowance is tight.
Peli 1510 Protector Carry-On Case
At 56.1 × 35.9 × 22.9 cm outside, it is built to meet the carry-on limits of most major airlines. It rolls on polyurethane wheels with stainless steel bearings, has a lockable telescopic handle and comes with no foam, Pick N Pluck foam or padded dividers.
Peli 1510 Protector Carry-On Case
Peli Storm iM2950 Expedition Case
Moulded from HPX resin and described as watertight and airtight. Four Press and Pull latches close automatically on impact, the Vortex valve prevents vacuum lock, and the in-line wheels roll over gravel and cobblestones. It comes in Black and Odd Green.
Peli Storm iM2950 Expedition Case
Peli Air 1615 Checked Baggage
The large rolling case for the hold. IP67 and MIL-SPEC, quiet-rolling stainless steel bearing wheels, a built-in business card holder and four interior options including a TrekPak divider system. It is available in Black, Yellow, Orange, Silver and French Blue.
The Water-Readiness Checklist
- O-ring: clean, uncut, seated evenly in its groove.
- Latches: every latch fully closed before the case goes near water.
- Valve: unobstructed, with no paint, stickers or mud.
- After salt: freshwater rinse, full dry, then open.
- Expectations: incidents yes, diving no.
- On boats: tether or clip the case. Waterproof does not mean easy to retrieve from the bottom.
- Padlock: if you lock the case for transport, use the padlock protectors on the latches and keep the hasps clean.
FAQ
Is IP67 the same as "fully waterproof"?
No. IP67 means dust-tight and able to survive temporary immersion up to about one metre for around 30 minutes. It is excellent for rain, spray and accidents, but it is not a rating for continuous or deep submersion.
Do all Peli cases have IP67?
The Peli Air product pages state IP67 and MIL-SPEC certification. The Protector and Storm pages describe the cases as watertight with an O-ring seal and a pressure equalisation valve. Check the product page of the exact model for the certification it lists.
How often should I replace the O-ring?
There is no fixed calendar. Inspect it a few times a year and after any hard use, and replace it as soon as you see nicks, flat spots, twisting or hardening. A fresh O-ring restores the original sealing.
Can I carry electronics in a Peli case on a kayak or paddleboard?
Yes, for the incident scenarios in this guide: spray, rain and a short unplanned swim. Clip or tether the case, because a closed case with air inside floats but can still drift away. Our guide to waterproof case or dry bag compares when each one works best.

The Honest Summary
IP67 is not marketing fluff. It is a lab-tested promise that your case shrugs off rain, spray, snow, mud and the classic overboard moment. It is also not a submarine, and pretending otherwise is how good gear meets bad ends. Respect the two limits (depth and time), give the O-ring five minutes of attention a few times a year, rinse after salt, and "is it really waterproof?" becomes a question you will never need to ask again.
