SEAL KIT CHECK VALVE (Crown CR111790-042)

A damaged check valve seal kit can allow internal leakage, reducing system pressure and causing erratic operation. This aftermarket replacement part references Crown as the OE maker and cross-references part number CR111790-042. The seal kit contains the seals and gaskets needed to rebuild the check valve assembly. Its primary mechanical function is to prevent fluid from bypassing the valve seat when closed. A common failure consequence is gradual loss of holding force, leading to drift or slow response under load. The item ships at approximately 0.006 pounds. Verify the serial number or application, then call (562) 693-7748.
