Designed for R12 and R22 refrigerant systems, this Vilter Outer Seat works with damped helical springs to deliver controlled, noise-free valve performance. It minimizes vibration and spring fatigue, while offering a durable sealing surface that resists pressure-induced wear. This part ensures consistent compressor efficiency, protects discharge valve components, and extends operational life in commercial refrigeration systems that use traditional halocarbon refrigerants
