Product Description

2 1/2" (63.5 mm) Brass Test Cap NST connects to a pressure gauge for easy static pressure tests on fire trucks, fire hydrants and other threaded pipe. Made of cast brass, this cap is available with a National Standard Thread (NST) inlet and forms a water-tight seal with a rubber gasket.

Quickly install a gauge or vent pressure with this 2 1/2" (63.5 mm) Brass Test Cap NST using the 1/4" (6.35 mm) Female NPT (FNPT) threaded bleeder/inlet. Compatible with gauges in a range of sizes and pressures, including our line of air and water pressure gauges.

Directly connecting a pressure gauge to the test cap is not recommended during static pressure tests. Bleeder valves can safely release excess pressure to prevent damage to gauges.

This 2 1/2" (63.5 mm) Brass Test Cap is compatible with our full line of 1/4" (6.35 mm) bleeder valves designed for static pressure tests. Single-ball-valve bleeders allow users to direct flow to a pressure gauge or to a bleeder using only one ball valve, while double-ball-valve bleeders use two ball valves to control gauge and discharge outlets separately. Quick-disconnect bleeders feature Parker Hannafin's high-quality quick-disconnect fittings to protect pressure gauges against unnecessary wear during installation and removal.
