Parker AVUIFI-4 Refrigeration Access Valve Assembly Brass

Product Description

The PARKER AVUIFI-4 is a refrigeration access valve assembly designed for use in sealed refrigerant systems where technicians need a reliable service port for pressure testing, refrigerant charging, and system diagnostics. Built from brass, this access valve assembly handles pressures up to 500 psi and fits a 1/4 inch tube outside diameter. It is a compact, single-unit assembly sold individually. HVAC-R technicians and refrigeration service professionals install this type of valve as a permanent or temporary service access point on refrigerant lines and system components.

This access valve assembly is suited for residential and light commercial refrigeration and air conditioning service work. It is commonly installed on suction or liquid lines where no factory service port exists, giving technicians the access needed to connect manifold gauges, vacuum pumps, or refrigerant charging equipment. The 1/4 inch tube OD sizing is standard for many small-diameter refrigerant line applications found in residential HVAC systems, refrigeration cases, and packaged equipment.

Key Features

• Rated to 500 psi maximum working pressure for refrigerant service applications
• Fits 1/4 inch tube outside diameter refrigerant lines
• Brass construction for corrosion resistance and durability in refrigerant environments
• Access valve assembly style provides a complete, ready-to-install service port
• Compact and lightweight at 0.06 pounds for easy handling in tight spaces

Compatibility

Designed as an OEM-style replacement and service-addition access valve for refrigerant systems using 1/4 inch OD tubing, consistent with standard residential and light commercial HVAC-R applications.

Installation Notes

Installation of refrigeration access valves should be performed by an EPA Section 608 certified HVAC-R technician. The system must be properly recovered and depressurized before any line penetration or valve installation. Follow applicable local codes and the equipment manufacturer's service procedures when selecting the installation location on the refrigerant circuit. Ensure all connections are leak-tested with an approved refrigerant leak detector after installation before returning the system to service.
