Franklin Fueling Systems 4 in. Flanged Vapor Check Valve w/ Sight Glass

Description

The sight glasses featured on this vapor recovery fitting can help detect liquid accumulation in the vapor manifold of a transport. A drain plug lets any extra fuel drain out, and the poppet prevents vapors from escaping when disconnected from the hose. A low pressure drop makes flow rates faster and vapor recovery safer. The adapter is constructed with a standard 4-inch TTMA flange, a 4-inch cam and groove, and a mounting pad for the Air Interlock Valve.
