Brass Gas Ball Valve for 1/2" Connections

This NIBCO GB2A valve controls gas flow in residential or light-commercial piping. It is a two-piece brass body with a standard-port brass ball and a square handle for manual operation. The straight inline design suits new installations or replacement of worn shut-off valves.

Replaces Leaking or Stiff Legacy Shut-Offs

Swapping an old valve for this model restores reliable on-off control when the existing handle seizes or the seal weeps. The upgrade is worth it when the system operates up to 600 psi and the thread size matches 1/2" FNPT on both ends. No special tools beyond standard pipe wrenches are required.

Suits Plumbers and DIYers Working on Gas Lines

Installers who need a straightforward, code-compliant ball valve for natural-gas or propane piping will find the specs match common requirements. Builders needing a full-port design, a locking handle, or a pressure rating above 600 psi should look at other configurations.

Questions about this item

What pipe thread size does the 1/2 in. FNPT connection require for a gas line?

The valve uses a 1/2 in. FNPT thread; match it to a 1/2 in. male NPT fitting and apply gas-rated pipe sealant on the male threads only.

How should the two-piece brass body be oriented during installation to avoid leaks?

Align the straight inline body with the flow direction, tighten each end to the recommended torque, and do not over-tighten the square handle stem nut.

When should the PTFE seats or stem packing be inspected on a 600 psi gas valve?

Inspect seats and packing annually or after any pressure surge; replace them if the handle turns stiffly or gas odour appears at the stem.
