Perko Black Plastic Locking Fuel Fill Insert

This Perko Locking Fuel Fill Insert uses a black plastic body with a zinc alloy lock cylinder. It adds a genuine layer of security to a fuel fill that would otherwise sit unlocked.

A dual purpose key opens both the fill cap and the locking insert. That means one key handles both parts of the job instead of juggling two separate keys at the dock.

It fits most Perko vented fills already installed on a boat. That makes it a straightforward add-on rather than a full fill replacement. Browse more marine pipe fittings.
