The Prism Supply Co. 1/4" NPT Petcock threads directly into a 1/4" 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.

Specifications

• Thread: 1/4" NPT (National Pipe Thread — tapered, seals on tightening)
• Hose barb: 5/16" diameter
• Built-in fuel filter included
• Twist on/off — fuel line does not rotate during operation
• No reserve
• Available in Brass or Stainless Steel

NPT Compatibility Note

Many custom and aftermarket gas tanks use a 1/4" or 3/8" NPT petcock bung. If your tank has a 22mm bung, petcock adapter nuts are available in brass or chrome to convert it to accept 1/4" or 3/8" NPT petcocks.

Available Options

• Brass — warm classic finish, great for polished or raw builds
• Stainless Steel — corrosion-resistant with a clean modern look
