Pelican Automatic Purge Valve Assembly with O-Ring

Field technicians and logistics crews rely on this auto purge assembly to keep sealed pelican case interiors stable when moving between job sites and transport holds. The unit threads into the existing valve port and automatically vents excess pressure while blocking water and dust ingress, so sensitive instruments stay protected without manual intervention.

During daily operations the assembly responds to pressure differentials caused by altitude shifts or rapid temperature swings, equalising the internal atmosphere before stress can deform the case seal or latch mechanism. The included O-ring seats against the valve housing to maintain the original IP rating, and the low-profile design clears foam inserts and divider walls. Maintenance teams can swap the valve in minutes using hand tools, reducing downtime on remote deployments where specialised equipment is unavailable.

Constructed from corrosion-resistant polymer with a stainless spring, the valve operates across a wide temperature range. Supplied with O-ring for immediate installation.
