The CPS PRODUCTS avs1 is a pack of 10 valve cores manufactured to stringent industry standards for HVAC service applications. Valve cores are the internal sealing components installed inside Schrader-style service ports on refrigerant lines, manifold gauges, and system access fittings. They provide a positive seal when the port is not in use and allow refrigerant flow when depressed by a service tool. These cores are a standard consumable for HVAC technicians performing system evacuation, charging, or pressure testing work.
The avs1 valve cores are suited for general HVAC refrigerant service work on residential and light commercial systems. Technicians replace valve cores when cores are leaking, damaged from repeated service tool contact, or cross-threaded during prior service visits. Having a 10-pack on hand supports efficient field service without repeated supply runs. These components are installed in Schrader-style service port fittings found on suction and liquid line access valves throughout refrigerant systems.
Designed as standard replacement valve cores for Schrader-style service port fittings used in residential and commercial HVAC refrigerant systems.
Valve core replacement is performed by licensed HVAC technicians using a valve core removal tool. Always recover refrigerant and confirm system pressure is relieved before removing an existing core from a live service port. A torque wrench or calibrated valve core tool should be used to avoid over-tightening, which can damage the port threads. Follow applicable EPA Section 608 guidelines when handling refrigerants during this procedure.
