Military-grade waterproof and dustproof equipment storage case, custom orders are available!
This #231815 small industrial waterproof safety case supports full-spec OEM & ODM customization. The military-grade container is integrally injection-molded with high-strength modified PP material, featuring an all-black wear-resistant industrial finish and a compact square inner cavity. It is ideal for storing precision testing instruments, DSLR camera lenses, small hardware tools, drones, outdoor shooting accessories and portable medical equipment. It comes with an integrated anti-slip front handle, and three types of liners are optional: empty bare cavity, wave-shaped shock-absorbing foam on the lid, and one-piece CNC milled EVA custom insert.
External dimensions: 270×231×185mm (10.63”*9.09”*7.28”)
Internal usable dimensions: 245×182×156mm (9.65”*7.17”*6.14”)
The case weighs only 1.15KG. With its lightweight military protective structure, it can be easily carried in backpacks, vehicles or during outdoor hiking.
The case is integrally injection-molded with thickened modified PP polymer material, featuring low-temperature resistance and anti-ageing properties. It is equipped with double-layer waterproof sealing gaskets, an automatic balanced pressure relief valve and two heavy-duty spring safety latches, reaching IP67 protection rating. It delivers six layers of military-grade protection: waterproofing, dustproofing, shock resistance, pressure resistance, moisture proofing and corrosion resistance. Reinforced metal hinges on the back ensure stable and durable opening and closing. The basic version features a smooth raw plastic empty cavity, while two types of shock-absorbing liners are available on request. Its compact and deepened inner cavity is designed to store small precision items for outdoor activities, construction sites and field work. Suitable scenarios include transporting outdoor photography gear, storing handheld site detectors, housing mini drone parts, carrying small shooting components, and transporting compact medical sampling devices for field missions. It addresses common problems such as water ingress and dampness of precision equipment, bumps and collisions during transit, erosion by outdoor sand and dust, and lack of secure storage for valuable small items. It is a universal military-grade waterproof portable protective case for photographers, surveying technicians, outdoor enthusiasts and electromechanical maintenance workers.
Military-grade modified PP integrally injection-molded case, resistant to extreme temperatures, drops and deformation:
The whole case is integrally molded from thickened modified polypropylene with no spliced seams. It will not crack or deform in a wide temperature range of -40℃ to 90℃. Reinforcing ribs are thickened around the case, so it will not dent when stood on by one person or stacked in multiple layers. It resists mild corrosion from engine oil, acids, alkalis and seawater, ensuring long service life at construction sites, outdoors in rain and snow, and coastal working environments.
IP67 double-layer waterproof sealing structure plus automatic pressure relief valve for all-weather moisture and water resistance:
A double-layer thickened high-elastic rubber sealing ring is fitted along the case rim, which is fully compressed and sealed once the two latches are fastened. An air pressure balancing relief valve is built into the front panel, which automatically equalizes internal and external air pressure under high altitude and drastic temperature changes to avoid negative pressure that makes the case hard to open. It keeps water out during short-term deep water immersion and heavy rain flushing, perfectly protecting cameras, circuit boards and precision sensors from moisture damage.
Dual heavy-duty spring safety latches that stay fastened amid jolting:
Symmetric thickened ABS spring latches are installed on the top of the case with strong clamping force. They will not pop open accidentally during vehicle vibration or violent shaking inside backpacks. The latches are integrally injection-molded without metal parts, so there is no risk of rusting; they keep working smoothly without jamming or cracking even with long-term outdoor use in humid conditions.
Front ergonomic integrated anti-slip handle for effortless portability:
An integrated anti-slip plastic handle is embedded on the front and molded together with the case for stable load-bearing without falling off. The case weighs only 1.15KG for lightweight carrying. The heightened inner compartment ensures ample storage space. It can be easily carried while hiking, on field missions or in vehicles, and fits neatly into the side pocket of a backpack.
Three types of liners for optional selection to deliver targeted protection for multiple industries:
Full-scenario customization services for bulk corporate procurement: A blank marking area is reserved on the front for laser engraving and silk-screen printing of corporate logos and equipment serial numbers. Customization of case colors and EVA liner slot layouts is available for bulk orders. ODM service is supported to adjust case thickness and latch structures to meet the demands of industries including surveying, photography, military, medical treatment and electromechanics.

Double-layer Waterproof Sealing Gasket + Pressure Relief Valve
A double-layer surrounding high-elastic rubber ring is installed at the case opening to achieve a gap-free closure after the latches are locked. The front pressure relief valve automatically balances internal and external air pressure, allowing the case to be opened effortlessly during mountain climbing or in conditions with sharp temperature fluctuations. It keeps moisture out during rainy, snowy and wading work, preventing lens fogging and short circuits of circuit boards.
Dual Heavy-Duty ABS Spring Latches
The case opening is fitted with a double-layer surrounding high-elastic rubber ring, ensuring a gap-free seal when the latches are fastened. The front pressure relief valve automatically balances internal and external air pressure, enabling easy case opening during mountain climbing or in environments with drastic temperature changes. It blocks moisture during rainy, snowy and wading operations to prevent lens fogging and short circuits on circuit boards.
One-piece Non-slip Handle
The built-in plastic handle on the front is injection-molded integrally with the case body. It features stable load-bearing capacity. You can carry the case fully loaded with equipment for a long time without feeling discomfort in your hand or suffering handle breakage. It outperforms external metal handles which tend to fall off easily.
Full Reinforced Rib Anti-Collision Structure
Thickened reinforcing ribs are distributed across the side walls, top and bottom of the case. Rounded anti-collision protrusions are designed at the four corners to disperse impact force when the case falls or collides. The case resists cracking and deformation and can withstand the static weight of one adult standing on it.

Q1: What is the waterproof rating of this waterproof safety case? Can it be fully submerged in water?
A: It has an IP67 protection rating. It can be temporarily immersed in 1-meter-deep clean water for 30 minutes without water intrusion, but it is not suitable for long-term deep-water submersion. After use at the seaside, rinse off salt with clean water to extend the service life of the case.
Q2: Will the case become brittle and crack when used outdoors in low-temperature conditions?
A: It is made of cold-resistant modified PP material. It will not crack at temperatures as low as -40℃. It can be normally used on construction sites and snowy mountains in winter. Just operate the latches gently when opening and closing in low temperatures.
Q3: How to clean engine oil and sediment on the case?
A: Rinse directly with clean water and a soft brush. Wipe off stubborn oil stains with neutral detergent. Store the equipment only after rinsing and air-drying. The inner wall made of original PP material is corrosion-resistant and hardly retains stains.
Q4: Can cameras and detectors fit inside completely?
A: Items whose length, width and height are smaller than the internal dimensions of 245×182×156mm can be fully accommodated. For larger equipment, you may consult us about the oversized waterproof safety cases of the same series.
Q5: What is the minimum order quantity for custom EVA liners?
A: The minimum order quantity for molded liners is 300 pieces. Independent grooves can be customized for cameras, probes and tools to store the whole set of equipment neatly in separate layers and zones.
Q6: Can damaged latches and hand grips be replaced separately with spare parts?
A: Latches, hand grips and pressure relief valves are all standardized universal parts. Contact customer service with the model number to arrange separate replacement parts delivery.
