Parker AVTS6D-4 Flare Female Branch Tee Depressor Valve

Product Description

The PARKER AVTS6D-4 is a forged brass flare female branch tee fitting with an integrated depressor access valve, rated for pressures up to 500 psi. Designed for refrigerant and compressed fluid systems, this tee allows a branch connection while providing direct access to a Schrader-style valve core through the depressor port. The forged brass body delivers the pressure integrity required for high-cycle service environments. HVAC technicians and refrigeration mechanics use this fitting when a branch line and a service port are both needed at the same junction point, eliminating the need for a separate access fitting in the line.

This fitting is suited for residential and light commercial refrigeration and air conditioning systems where 1/4 inch OD flare connections are standard. The depressor access valve makes it practical for charging, evacuation, and pressure testing without disconnecting the line. It installs wherever a tee junction with built-in service access is required in a refrigerant circuit or similar high-pressure fluid system.

Key Features

• Maximum working pressure of 500 psi for high-pressure refrigerant circuit use
• Forged brass body provides superior pressure integrity over cast alternatives
• Integrated depressor access valve allows service port access without additional fittings
• 1/4 inch tube OD flare female connections on all ports
• Compact single-piece design reduces potential leak points at branch junctions

Compatibility

Designed as an OEM-style service fitting for refrigerant and compressed fluid branch connections using standard 1/4 inch OD flare female fittings in HVAC, refrigeration, and related high-pressure systems.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician following applicable EPA Section 608 regulations for refrigerant handling. Recover all refrigerant and depressurize the system before removing or installing any line fittings. Use a calibrated torque wrench and flare nut wrench to avoid cross-threading or over-tightening the flare connections. Inspect the flare seats for damage before assembly and verify the depressor valve core is seated correctly before returning the system to service.
