CONBRACO 4000902 2 1/2" - 3" 40 SERIES 2ND CK VALVE KIT

This is the complete check assembly.  It is the same check for the 40 series, double check, but it is only for the #2 check on the Conbraco 40 series reduce pressure assembly.  This fits both the 2 1/2" and 3" assemblies.  Also comes with the cover o-ring.
