Parker AVC1-4 Forged Male Cross Access Valve 500 Psi

Product Description

The PARKER AVC1-4 is a forged male cross access valve designed for refrigeration service applications. Built from brass, it provides a durable, leak-resistant connection point used during system charging, evacuation, and pressure testing. The valve accepts a 5/16-inch tube OD and features a 1/4-18 male pipe thread connection. It is rated to a maximum working pressure of 500 psi, making it suitable for common refrigerants used in residential and light commercial HVAC systems. HVAC technicians install this valve as a permanent or temporary access point on refrigerant lines to enable gauge manifold connections without cutting into the line.

This access valve is used in refrigeration and air conditioning systems where a reliable service port is required. The forged male cross configuration allows manifold gauge sets to be connected for pressure checks, refrigerant recovery, or system recharge. Typical installation scenarios include field service work on split systems, package units, and refrigeration equipment. It is well-suited for residential and light commercial applications where brass construction and a compact form factor are required at the service port.

Key Features

• Forged brass construction for durability and corrosion resistance in refrigerant service environments
• 500 psi maximum working pressure rating for common refrigerant applications
• 5/16-inch tube OD connection for standard refrigerant line fitment
• 1/4-18 male pipe thread for reliable, leak-free mating
• Male cross access valve design enables gauge manifold connection without line modification

Compatibility

Designed as an OEM-style replacement or field-installed access valve for refrigeration and air conditioning systems requiring a 5/16-inch tube OD, 1/4-18 male pipe thread service port rated to 500 psi.

Installation Notes

Installation should be performed by a licensed HVAC technician or refrigeration mechanic in accordance with applicable EPA Section 608 regulations and local codes. Recover or isolate system refrigerant before opening any refrigerant circuit. Ensure all connections are torqued to fitting manufacturer standards using appropriate refrigeration wrenches and that the service port cap is reinstalled after each use to prevent contamination and leakage. Verify system pressure integrity with a manifold gauge set before returning the equipment to service.
