Prism Motorcycle Supply manufactures these unique petcocks in the USA. This brass petcock fits 3/8" NPT bungs on your gas tank. 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.
Many custom and aftermarket gas tanks use a 1/4 inch NPT or 3/8 inch 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.
On / Off function only, no reserve.
Polished brass construction with brass fuel filter
