This is a first or second check kit. Kit consists of: a seat, seat O-ring, disc assembly, spring, check cage, and cover O-ring.

Are these genuine Watts parts?

Yes. This is the factory RK 007-CK4 1/2 kit built with genuine Watts OEM components. Aftermarket parts can void your assembly approval and are commonly rejected by inspectors at annual test time.

Which kit do I need if my relief valve failed the test?

Not this one — this kit services the check valve. A failed relief valve needs the RV (rubber parts) or VT (total relief valve) kit for 007 in your size; a total repair (T) kit covers the relief valve and both checks.
