Parker AVTS-8 Solder Tee Access Valve 500 Psi 1/2 Inch

Product Description

The PARKER AVTS-8 is a brass solder tee access valve rated for up to 500 psi, designed for use in refrigeration and HVAC systems where technicians need a reliable service port integrated into the refrigerant line. The tee configuration allows the valve to be installed inline on a 1/2-inch OD copper tube using standard solder joints, creating a permanent access point for pressure testing, refrigerant charging, and system diagnostics. At 0.07 pounds, the AVTS-8 is a compact, lightweight fitting suited for tight equipment spaces. Licensed HVAC technicians and refrigeration mechanics are the primary installers of this component.

This access valve is used in residential and light commercial refrigeration and air conditioning systems where a permanent Schrader-style service port is needed on a copper refrigerant line. The solder tee design makes it appropriate for new installations or retrofit applications where an access point needs to be added to an existing line set. Its brass construction provides corrosion resistance and durability in refrigerant-side environments. The 1/2-inch tube OD sizing fits common suction and liquid line configurations found across a wide range of split and packaged HVAC systems.

Key Features

• 500 psi maximum working pressure for compatibility with common refrigerants including R-410A systems
• 1/2-inch tube OD solder connection for secure, leak-resistant installation on copper line sets
• Tee body design provides an inline service port without interrupting primary line flow
• Brass construction offers corrosion resistance and long service life in refrigerant environments
• Compact and lightweight at 0.07 pounds, suitable for space-constrained installations

Compatibility

Designed as an OEM-style solder tee access valve for use on 1/2-inch OD copper refrigerant tubing in residential and commercial HVAC and refrigeration systems.

Installation Notes

Installation requires recovery of any existing refrigerant charge before cutting or modifying the refrigerant line, in accordance with EPA Section 608 regulations. A licensed HVAC technician should perform all soldering work using a nitrogen purge to prevent oxidation inside the copper tubing. After installation, pressure-test the joint before recharging the system to confirm a leak-free solder connection. Follow all applicable local mechanical codes and the system manufacturer service guidelines during installation.
