Petcock 3/8 NPT

The Prism Supply Co petcocks are guaranteed for life! If you're having an issue with it you can send it back to them and they will rebuild it for no additional cost!

This unique 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. We recommend using our 1/4" fuel line for a snug, leak-proof fit. Rotating the cylindrical piece with the two grooves is how the fuel is toggled on and off. The fuel line 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.
