Product Overview
CR Foam Gasket with PSA is a precision-engineered circular gasket designed for reliable sealing, cushioning, and vibration damping in industrial, automotive, and household applications. Made from high-quality Chloroprene (CR) closed-cell foam and featuring a pressure-sensitive adhesive (PSA) backing, it ensures easy installation and stable performance.
Ideal for valves, pumps, electrical enclosures, and other equipment requiring leak-proof sealing and shock absorption, this gasket delivers long-term durability and consistent functionality under various pressures and temperatures.
Structure & Cross-Section
