Prism Supply, Fuel Valve, 1/4″ Brass
This unique brass petcock fits direct to either a 1/4″ or 3/8″ NPT bung on your gas tank. This keeps your gas tank looking very clean. It features a 5/16″ diameter hose barb on one end and a fuel filter on the other. Rotating the cylindrical piece with the two grooves is how the fuel is toggled on and off. The fuel line will not and does not rotate while toggling the fuel on/off. No reserve.
Many custom and aftermarket gas tanks use a 1/4 inch NPT or 3/8 NPT petcock. NPT stands for National Pipe Thread and it is a tapered thread that seals as you tighten the petcock into the threaded fitting on your gas tank. Lowbrow Customs makes petcock adapter nuts in both brass and chrome that allow you to adapt your 22mm petcock bung to accept either a 1/4 inch NPT or 3/8 inch NPT petcock.
Length measured without hose barb and filter.
