The Prism Supply Co. 3/8" NPT Petcock threads directly into a 3/8" NPT bung on your gas tank for a clean, flush look with no external hardware cluttering your build. A 5/16" diameter hose barb on one end and a built-in fuel filter on the other keep your fuel system tidy and protected. Toggle fuel on and off by rotating the cylindrical piece — the fuel line stays stationary while you do it.
We recommend pairing this with 1/4" fuel line for a snug, leak-proof fit.
Lifetime Guarantee: All Prism Supply Co. petcocks are guaranteed for life. If you ever have an issue, send it back and they'll rebuild it at no charge.
Many custom and aftermarket gas tanks use a 3/8" NPT petcock bung. NPT (National Pipe Thread) is a tapered thread that seals as you tighten the petcock into the fitting. If your tank has a 22mm bung, adapter nuts are available in brass or chrome to convert it to accept 3/8" NPT petcocks.
