Largest range of waterproof equipment cases from a UK supplier

Waterproof cases are the best option for keeping your company’s equipment and tools dry or protecting them from physical damage.

Many businesses use waterproof cases to protect fragile, expensive or specialist items. Waterproof equipment cases have ingress protection (IP) ratings indicating water and dust resistance. Typically tough and durable, waterproof hard cases with foam inserts also protect against impact and mishandling. Popular options include Peli™, Storm, and Explorer.

At GWP, we ensure you get the most competitive pricing and a vast choice of brands, sizes and options, and you can source your cases and foam inserts together for improved compatibility and performance. Our team of experts, with in-depth case and industry specific knowledge, can provide impartial and free advice too.

More info on waterproof cases

Besides providing resistance to water, moisture, and dust, waterproof cases are typically the toughest and most durable protective cases you can buy. So, if you have important or expensive equipment, tools, products, or components that need to be protected, you can choose from a wide range of equipment cases with foam that provides a high-performance solution.

IP rated cases

While the obvious and crucial feature of any waterproof case is its IP rating, cases of this type are typically the toughest and most durable, too. Most are certified to IP67, meaning complete resistance to water and dust, even if submerged.

However, being an exceptionally competitive market, virtually all waterproof cases boast many additional features and benefits.

Waterproof plastic case features

For example, most waterproof cases include pressure relief valves, secure latches, eyelets to attach padlocks, lid stays, stacking features, telescopic handles, and inline wheels (on larger sizes).

Besides this, every aspect of the various cases is thoroughly researched, developed, and extensively tested. This ensures that whatever brand of waterproof case you choose is secure, easy to use, and offers exceptional protection from shock, impact, and vibration (as well as water and dust).

Waterproof hard cases with foam

Waterproof equipment cases typically come with two foam interior options.

The first of these is a standard, cubed foam insert. Also known as pick n pluck™ foam when supplied with Peli and Storm Case, the foam insert comprises multiple layers, each divided into one-centimetre cubes. The end user can remove these individual cubes as required.

The key benefit of cubed foam is that it can be easily tailored to specific items, reducing movement in transit and adding a layer of cushioning protection. This is particularly cost-effective for low-volume and one-off case requirements.

Custom foam inserts

Custom foam inserts are the more appropriate choice if a higher volume of cases is required or the protection levels must be the highest possible.

At GWP Protective, we design and manufacture custom inserts to the exact shape of your products or equipment. Specialist software can also calculate the precise level of cushioning protection required.

A final option, if looking to house specialist electronics, is a bezel kit.
Comprised of a metal frame and moulded corner pieces that will fit at any depth within the case, the panel mount kit allows you to mount the equipment directly into the case.

Waterproof case FAQs

Do waterproof cases work?

Waterproof equipment cases such as those from Peli, Hardigg, SKB, Nanuk, B&W, and others offer complete protection from water. This protection ranges from rain splashes to being fully submerged for prolonged periods. They also protect against dust entering the case.

Do these cases come with lifetime guarantees?

Most waterproof cases come with a warranty or guarantee from the manufacturer. For example, all Peli cases have a lifetime guarantee, whilst others, such as B&W, provide a 30-year warranty. When sourcing these cases for your business, these guarantees give you added peace of mind.

What is a pressure relief valve?

Waterproof cases must deal with potential pressure changes, primarily achieved through pressure relief valves. These valves, many of which automatically adjust, equalise the pressure between the inside and outside of the case. This feature is also advantageous for using cases in high-altitude locations and aircraft luggage holds.

What is a roto mould case?

Whilst most waterproof cases are injection moulded, a number use rotational moulding. Rotational moulding is when a heated hollow mould is filled with a charge or shot weight of the material and slowly rotated (usually around two perpendicular axes). This process causes the softened material to disperse and stick to the walls of the mould.

What are IP ratings?

IP is an abbreviation for “ingress protection”. IP ratings are a measure of protection an item, such as a protective case, offers against the ingress of foreign bodies. The rating also covers solid foreign bodies, such as sand and dust, but is, in effect, a measure of how resistant a case is to water.

Can foam inserts be added to a waterproof case?

Waterproof cases with foam inserts provide the highest levels of protection for any tools, products, or items. For this reason, many businesses also specify custom foam inserts when sourcing waterproof cases.

What are bezel kits?

Bezel kits are rectangular aluminium frames that allow you to mount electronic equipment into the lid or base of a waterproof case. Many businesses mount microcomputers, testing equipment and metrological devices within their waterproof cases. Using bezels allows for ease of transportation and use, alongside the protection the case provides.

Do waterproof cases have wheels?

Most larger waterproof cases feature inline wheels to aid their transportation. Inline wheels improve ease of use when pulling the case, even over rough terrain. Wheels are usually integrated into the body of the case to avoid them becoming damaged, plus minimising the outer dimensions. Any case that includes wheels usually features a telescopic, retractable handle.
