Parker AVUR3-4 Female Flare Connector Access Valve 500 Psi

Product Description

The PARKER AVUR3-4 is a female flare connector access valve designed for refrigeration systems where technicians need a reliable service port for pressure testing, refrigerant charging, and system diagnostics. Constructed from brass, this valve accepts a 1/4 inch tube OD connection and is rated to a maximum working pressure of 500 psi. The female flare connector design provides a leak-resistant interface with standard flare fittings used throughout residential and light commercial refrigeration and HVAC systems. Licensed HVAC technicians and refrigeration service pros install this valve as part of routine service work or new system commissioning.

This access valve is suited for refrigeration lines and HVAC refrigerant circuits where a dedicated service port is required. Its compact size and brass construction make it appropriate for tight equipment spaces in split systems, refrigeration cases, condensing units, and similar refrigerant-bearing equipment. The female flare connector interface aligns with standard refrigerant line flare fittings commonly found across commercial and residential refrigeration applications.
