Perko 0571DP4BLK 90 Degree Black Gas Tank Vent with Swivel Elbow

The Perko 0571DP4BLK is a 90 degree angled gas tank vent fitting with a swivel elbow, built for venting gasoline fuel tanks on boats. The zinc alloy elbow rotates to any position, so it can be aimed to keep water and spray away from the vent opening regardless of how the through-hull is oriented. A black polymer splash guard cap covers the vent opening, and a removable 30 mesh stainless steel wire screen flame arrestor is built in for use with gasoline applications, helping prevent flame or spark intrusion into the fuel system while still allowing the tank to vent properly.

This vent is sized for 5/8 inch hose and is designed for hulls up to 3/4 inch in maximum thickness. It is a universal-fit deck vent, suitable for gasoline-powered boats where a compact, rotatable vent elbow with an integrated flame arrestor screen is needed. The removable screen design allows the flame arrestor mesh to be cleaned or replaced without removing the whole fitting.
