Parker Core Removal Tools

Overview

The PARKER AVTS4D-4 is a forged brass swivel tee fitting with an integrated depressor access valve, designed for refrigerant and compressed fluid systems operating up to 500 psi. The fitting accepts 0.25-inch tube OD on the run port and features a flared female connection style. The swivel design allows the tee to rotate during installation without disturbing the tubing run, reducing the risk of joint stress. The built-in depressor pin provides direct access to the system service port without requiring a separate Schrader core tool. HVAC technicians and refrigeration service pros use this fitting for line-set service access points in split systems and commercial refrigeration circuits. This fitting is suited for residential and light commercial HVAC and refrigeration applications where a compact, inline service access point is needed on a 0.25-inch flare line. It is typically installed on suction or liquid lines where periodic refrigerant charge checks or recovery connections are required. The forged brass construction handles the pressure and temperature cycling common in active refrigerant circuits. Sold individually, it is a direct field-install component requiring no special adapters beyond standard 0.25-inch flare tooling.
