Parker AVT3-4 Forged Male Run Tee Access Valve Brass

Product Description

The PARKER AVT3-4 is a forged brass male run tee access valve rated for up to 500 psi of working pressure. It features a 1/4-18 male pipe thread connection and is designed for use with 5/16 inch tube OD refrigeration lines. The forged brass construction provides durability and leak-resistant performance in refrigerant service applications. HVAC technicians and refrigeration service professionals install this valve to provide core access points on refrigeration systems without interrupting the main line flow. Its compact, forged body suits both new installations and field service work.

This access valve is used in refrigeration and air conditioning service applications where a run tee configuration is needed to tap into an existing refrigerant line. The male pipe thread inlet allows direct connection to standard fittings in residential and light commercial refrigeration circuits. The 5/16 inch tube OD sizing fits tubing commonly found in smaller refrigeration and HVAC systems. It is well suited for adding service ports during system commissioning, maintenance, or retrofit work on refrigerant circuits.

Key Features

• Forged brass body for strength and corrosion resistance in refrigerant service
• 500 psi maximum working pressure rating
• 1/4-18 male pipe thread connection for standard fitting compatibility
• 5/16 inch tube OD sizing for common refrigeration line dimensions
• Run tee configuration maintains main line flow while providing service access

Compatibility

Designed as an OEM-style replacement or new-installation access valve for refrigeration and air conditioning systems using 5/16 inch tube OD lines with 1/4-18 male pipe thread fittings.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician in accordance with applicable mechanical and refrigeration codes. Recover refrigerant and relieve system pressure before installing or replacing any access valve. Use appropriate flare or fitting tools to ensure a leak-free connection at both the pipe thread and tube OD joints. Verify the valve core is fully seated and pressure-test the assembly before returning the system to service.
