Parker AVTS4-4 Swivel Tee Access Valve 500 Psi 1/4 Inch

Product Description

The PARKER AVTS4-4 is a forged brass swivel tee access valve rated to 500 psi maximum working pressure with a 1/4 inch tube outside diameter connection. Designed for refrigerant and fluid system service work, this fitting features a flared female run swivel tee configuration that allows technicians to access system pressure points without disturbing primary tubing runs. The forged brass construction provides reliable sealing performance under the pressure cycles common in HVAC and refrigeration service environments. Licensed HVAC technicians and refrigeration service pros are the primary installers.

This access valve is suited for use in residential and light commercial HVAC and refrigeration systems where 1/4 inch flare line access ports are required. It is commonly installed at service access points on refrigerant circuits, enabling gauge manifold connection and pressure testing without requiring line disconnection. The swivel tee design allows the valve body to rotate for easier alignment in tight equipment compartments.
