Access Service Valve 1/4

The JB Industries A33000 access service valve provides a 1/4 inch SAE connection for HVAC systems. It is intended for technicians who need a back-seating control valve during service procedures. The valve is designed for use with copper fittings that are purchased separately. Buyers who require an integrated fitting will need a different configuration.

Thermals Noise Power Draw

The valve is a passive mechanical component with no electrical or moving parts that generate heat or sound. It adds no power draw to the system and operates silently during refrigerant handling. Thermal performance depends entirely on the surrounding system conditions rather than the valve itself.

Questions about this item

How is the 1/4" SAE access service valve installed on copper fittings?

Connect the valve to the 1/4" SAE flare on the copper fitting and tighten with a wrench; the step often missed is fully back-seating the control stem after installation to prevent refrigerant leakage.

What maintenance does the back-seating control valve require over time?

Periodically check the valve stem packing for leaks and lubricate if the stem becomes stiff; replace the valve if the back-seat seal no longer holds pressure during system service.
