Access Valve Extension for HVAC Lines
The JB Industries A31002-G is a 1/4-inch access valve extension tube built for HVAC control work. It features a brass and copper construction with a 2-inch copper tube extension and a 1/8 ODS connection. The assembly includes a cap and valve core and is designed for use with tubing connections. This component suits technicians servicing refrigeration and air-conditioning systems.
Straightforward Flare Fitting Install
Installation involves threading the flare nut onto the mating 1/4-inch port and tightening to the proper torque with a flare wrench. The valve core should be seated before pressurising the system. Common issues include cross-threading the soft brass nut, over-torquing which splits the flare, and forgetting to reinstall the cap, which leaves the Schrader core exposed to contamination and leakage.

Questions about this item
How can I verify the 1/4 in. access valve is working correctly after installation?
Pressurise the system and check for leaks at the copper brazed joint and the 1/8 ODS connection; the valve core should hold pressure and the included cap should seal the port when removed.
What comes in the pack and what extra parts are needed for a tubing connection?
The PK5 pack contains five access valves each with a cap and valve core; you must supply compatible tubing and brazing materials to complete the 2 in. copper tube extension connection.
