More info on Waterproof Cases

Tough and durable plastic cases packed with features

Whilst the obvious and critical feature of any waterproof case is its’ IP rating (with the majority certified to IP67 – meaning complete resistance to water and dust, even if submerged), cases of this type are typically the toughest and most durable too.

However, being an exceptionally competitive market, virtually all waterproof cases also boast a wide range of additional features and benefits.

For example, the majority of cases will include pressure relief valves, secure latches, eyelets to attach padlocks, lid stays, stacking features and even 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, it will be secure, easy to use, and offer exceptional protection from shock, impact and vibration (as well as water and dust).

Waterproof cases with foam

Waterproof equipment cases typically come with 2 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 is divided into layers, and then further divided into one cm cubes which can be removed as required by the end user.

The key benefit of this is that the foam can be perfectly 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.

If a higher volume of cases is required – or the protection levels must be the highest possible – then custom foam inserts would be the more appropriate choice.

These would see the foam designed and manufactured to the exact shape of your products or equipment, whilst it is also possible to 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 bezel (or panel mount kit as they also referred to) allows the equipment to be mounted directly into the case.

Waterproof Case FAQs

Common questions regarding waterproof cases

With so many different options to choose from (not to mention the range of sizes, colours, features etc.), choosing a waterproof case can be somewhat daunting. It also means there are numerous questions that you will typically have.

A number of these most frequently asked questions are covered below but, if you cannot see the info you need, please contact a member of the GWP team for further assistance.

Do waterproof cases actually work?

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

Are flight cases waterproof?

Traditional flight cases are not waterproof, although will provide some protection from rain etc. However, the new EXOCase™ is a truly waterproof flight case (the worlds first in fact), combining the performance of a moulded case with the size flexibility of a custom flight case.

What is a Peli case?

Peli™ (or Pelican™) is the original brand of moulded plastic, waterproof case. Due to their popularity, “peli case” is often used as a generic term for waterproof cases of a similar type. However, due their popularity, there are now a wide range of Peli case alternatives available.

Do these really come with lifetime guarantees?

The majority of waterproof cases will come with some form of 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. This gives you added peace of mind when sourcing these cases for your business.

What is a pressure relief valve?

With the ability to be submerged underwater for prolonged periods of time, it is essential that waterproof cases can deal with potential changes in pressure. This is primarily achieved through the use of pressure relief valves, many of which automatically adjust and equalise the pressure between the inside and outside of the case. This is also advantageous if the case is used in high altitude locations or stored in the hold of an aircraft.

What is a roto mould case?

Whilst most waterproof case are injection moulded, a number are manufactured using rotational moulding (whereby a heated hollow mould which is filled with a charge or shot weight of material is then slowly rotated (usually around two perpendicular axes), causing the softened material to disperse and stick to the walls of the mould).

What are IP ratings?

Standing for ingress protection, IP ratings are a measure of protection an item such as a protective case offers against the intrusion / ingress of foreign bodies.  This also covers solid foreign bodies, such as sand and dust, but is in effect, a measure of how waterproof a case is.

Can I add foam inserts to a waterproof case?

Yes! Waterproof cases that have foam inserts provide undisputedly the highest levels of protection for any tools, products, or items. This is why many businesses will also specify custom foam inserts when sourcing waterproof cases.

What are bezel kits?

Bezel kits are effectively an aluminium, rectangular frame that is used as a system to mount various types of equipment (predominantly electronic) into either the lid or the base of the case.  Microcomputers, measurement and metrological devices, testing equipment and much else can all be mounted within the case, allowing for ease of transportation / use and of course the protection provided by the case itself.

Do waterproof cases have wheels?

The larger waterproof cases – regardless of manufacturer – tend to feature inline wheels to aid their transportation. Usually integrated into the body of the case to avoid them becoming damaged, plus minimising the outer dimensions, inline wheels enable ease of use when pulling the case – even over rough terrain. Any case that benefits from these will also generally feature a telescopic, retractable handle too.
