1/4" Access Valve Extension Tubes, Pack of 5

The JB Industries A31005 pack supplies five brass and copper extension tubes designed for HVAC service work. Each tube measures two inches in length and features a 1/4 inch inside diameter with a 5/16 inch outside diameter connection. They are rated for use with all CFC, HCFC and HFC refrigerants commonly encountered in the field.

For technicians servicing standard Schrader access

These extensions suit professionals who need reliable, reusable valve access during refrigerant recovery, charging or pressure testing. The brass and copper construction resists corrosion from common refrigerants. Shops requiring different connection sizes, longer reach or metric-threaded fittings should look at alternative configurations not covered by this specific pack.

Questions about this item

What size flare fitting do I need on my manifold gauge hose to connect these 1/4 inch ID tubes?

The tubes have a 1/4 inch inside diameter, so they accept a standard 1/4 inch SAE flare nut found on most HVAC service hoses.

Can I leave the 5/16 inch OD end connected to an older Schrader valve core while I service the system?

Yes, the 5/16 inch outside diameter slips over standard 1/4 inch access valve stems, letting you keep the core in place during charging or recovery.
