PREVENT UNAUTHORIZED USE: The Flow Security Systems FSS-377 vented fuel cap is a quick and inexpensive way to safeguard costly fuel and oil from theft, tampering, siphoning and vandalism. The FSS-377 is perfect for anyone who want to secure their fuel tanks. MULTIPLE USES: The FSS-377 is designed for use on mobile fuel transfer tanks, as well as above ground commercial tanks. COMPATIBILITY: Fits all 2'' male threaded tanks. Cap is secured to adapter with any 5/16th diameter shackle padlock (not included). INSTALLATION: The adapter is firmly connected to the tank via a wrench. It can be permanently set in place with use of a thread locker. HEAVY DUTY: Manufactured to the highest standards and built to last a lifetime. Cap and adapter are made from high quality carbon steel, CNC machined for precise fit and function, and case hardened for durability and resistance to drilling and damage. BUILT-IN VALVE: The FSS-377 uses a built-in valve to equalize pressure and vacuum. The valve allows the tank to vent when pressure reaches 1.5 psi and releases vacuum at 1.5 oz RETAINING CHAIN: Attached to the inside of the cap is 10” stainless steel chain to retain the cap to the tank during a fill up. This is removable if a larger nozzle needs to be accomodated. SEALED SYSTEM: Inside gasket provides sealing and prevents spillage of the tank contents.
