Perko EPA Compliant Replacement Pressure Relief Gas Caps

Fig 0680 Replacement Cap with Pressure Relief

The Perko pressure relief valve is a double acting valve. It relieves pressure over 1 psi meeting both EPA and CARB requirements and also relieves vacuum allowing additional make up air into the system when engines are running. Perko installs this pressure relief valve in a wide range of fuel fills & fuel caps and also in P-traps giving builders options for system design.

These caps meet the CARB and EPA requirements of U.S.C.G. Safety Standards (July 31, 2011) for 40 CFR Parts 9, 60, 80 et al. Control of Diurnal Emissions From Nonroad Spark-Ignition Engines and Equipment.
