ASCO C131204 Pneumatic Valve Seal Repair Kit 1/2

ASCO C131204 Pneumatic Valve Seal Repair Kit is a 1/2" port rebuild kit designed for ASCO’s bronze-bodied, two-way, normally closed pneumatic valves in the E290 family. The kit provides the essential seals and packing required to restore valve performance after wear or leakage, including disc packing, a lock nut, a valve body seal, and a washer-disc packing retainer, all sized for a 1/2 in port. It is intended for air-operated control and supports a maximum operating pressure of 240 psi, making it suitable for standard plant pneumatic circuits. The C131204 kit is the official repair part for ASCO 1/2" E290 bronze valves, enabling maintenance teams to reseal critical interfaces without replacing the entire valve body. With its bronze body compatibility and 1/2" port, the kit supports reliable reseating and long service life in automation and process-control environments where compact, proven sealing components are required. Its compact form and included packing components help minimize downtime during maintenance by allowing quick, precise resealing of the valve.
