Compact waterproof case for small electronics

The Pelican M40 is an IP67 rated micro case built to protect compact devices such as smartphones, digital cameras or precision tools from water, dust and crushing forces. Its clear yellow body lets you identify contents at a glance without opening the lid. Dual latches and a padlock hole add physical security for valuable items. Made in the USA, it suits anyone needing rugged, portable protection for small gear.

Removable liner and pressure valve improve daily use

A no-slip bottom liner keeps contents from shifting during transport and can be removed for cleaning or custom fitting. The automatic pressure equalisation valve balances internal pressure after altitude or temperature changes, preventing vacuum lock while maintaining the watertight seal. Together these features make the case practical for repeated opening in changing environments.

Simple latch system, watch the O-ring seal

The dual latches open and close by hand with no tools required, and the padlock hole accepts a standard shackle for added security. The critical step is ensuring the separate O-ring gasket sits clean and undamaged before each closure; debris or a twisted ring will break the watertight seal. No complex installation is needed beyond verifying the gasket condition.

Questions about this item

How often should I replace the O-ring gasket to keep the IP67 seal intact?

Inspect the O-ring before each trip; replace it if you see cuts, flattening or loss of elasticity so the watertight seal stays reliable.

What fails first if the case stays submerged at the IP67 limit for long periods?

The O-ring seal is the first barrier; prolonged pressure at depth can deform it and allow water ingress before the polycarbonate shell yields.

Does the automatic pressure equalisation valve make any noise or let heat escape during all-day use?

The valve operates silently and only balances pressure; it does not vent heat or create audible noise while the case sits closed.
