Parker AVUS-42 Access Valve 500 Psi 1/8 Inch Solder

Product Description

The PARKER AVUS-42 is a straight solder connector refrigeration access valve designed for use in refrigerant circuit service and charging applications. Rated to a maximum of 500 psi, this valve provides a reliable service port connection at 1/8 inch tube OD. The body is constructed from brass, offering corrosion resistance in refrigeration environments. It connects via a straight solder fitting, making it suitable for copper tubing systems common in residential and light commercial refrigeration and HVAC work. HVAC technicians and refrigeration mechanics install this fitting when adding or servicing access ports on refrigerant lines.

This access valve is used in refrigeration and air conditioning systems where a straight inline solder connection is required. It is well suited for residential and light commercial HVAC and refrigeration equipment, including applications where technicians need to establish a service port on an existing copper line set or component. The straight solder connector style allows for clean, permanent integration into the refrigerant circuit during installation or retrofit service calls.

Key Features

• 500 psi maximum pressure rating for use in common refrigeration and HVAC refrigerant systems
• 1/8 inch tube OD straight solder connector for direct copper tubing integration
• Brass construction provides corrosion resistance in refrigerant service environments
• Straight body orientation suits inline installation on refrigerant lines
• Compact, lightweight design at 0.04 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style replacement or add-on access valve for refrigeration and HVAC systems using 1/8 inch OD copper tubing with solder-type connections.

Installation Notes

Installation should be performed by a licensed HVAC or refrigeration technician in compliance with applicable EPA Section 608 refrigerant handling regulations. Recover all refrigerant from the system before cutting or soldering any refrigerant lines. Use proper silver-solder or brazing alloy appropriate for refrigeration copper tubing and purge the line with dry nitrogen during the brazing process to prevent internal oxidation. Pressure-test the joint and leak-check before recharging the system.
