Cps Products av4 Copper Tube Access Fitting 1/4 in Od

Product Description

The CPS PRODUCTS av4 is a copper tube access extension fitting designed for use in refrigeration and HVAC service applications. This fitting provides a reliable access point for refrigerant system service work, allowing technicians to connect gauges, vacuum pumps, or charging equipment to a system line. Constructed from copper, it features a 1/4 inch outer diameter and a 3/16 inch inner diameter, making it suited for standard access valve and line tap configurations encountered in the field.

This fitting is used in residential and light commercial HVAC and refrigeration service work. It is typically installed by licensed HVAC-R technicians during system diagnosis, evacuation, or refrigerant charging procedures. The small-diameter copper construction makes it appropriate for tight spaces and retrofit access situations where extending an existing access point is necessary.

Key Features

• Copper construction for reliable brazing and compatibility with refrigerant systems
• 1/4 inch OD x 3/16 inch ID dimensions suit standard HVAC-R access valve applications
• Extension design allows technicians to reach recessed or difficult service ports
• Compact form factor for use in confined equipment spaces

Compatibility

Designed as an OEM-style access extension fitting for standard 1/4 inch OD copper tube connections commonly found in residential and light commercial HVAC-R systems.

Installation Notes

Installation should be performed by a certified HVAC-R technician in accordance with applicable EPA Section 608 regulations and local codes. Recover all refrigerant from the system before cutting or brazing any line components. Use appropriate brazing alloy and flux for copper-to-copper joints, and pressure-test the fitting before returning the system to service.
