The CPS PRODUCTS avt44 is a three-port access valve tee fitting designed for refrigerant system service work. It connects a 1/4 inch female hex port to a 1/4 inch SAE male port and a 1/4 inch male port, giving technicians a reliable service access point on HVAC and refrigeration lines. Each fitting ships with a cap and a Schrader core installed. This pack contains three fittings, making it a practical option for stocking a service van or completing multi-unit jobs. HVAC technicians and refrigeration mechanics are the primary installers.
These fittings are used in residential and light commercial HVAC and refrigeration service applications. They are installed on suction or liquid line access points where a technician needs to attach manifold gauges, add refrigerant, or check system pressures. The included cap and core allow the fitting to remain sealed when not in service. The three-pack quantity suits contractors servicing multiple systems in a single visit or maintaining a working supply of fittings on hand.
Designed for use in standard HVAC and refrigeration service applications where 1/4 inch SAE access valve connections are required.
Installation should be performed by a licensed HVAC or refrigeration technician in accordance with applicable EPA Section 608 regulations. Recover all refrigerant and confirm the system is depressurized before removing or installing access fittings. Use appropriate wrenches on the hex flats to avoid deforming the fitting body. Confirm the Schrader core is fully seated and the cap is hand-tight before returning the system to operation.
