Description
The 40003918-007 is an adaptor plate and ball assembly from Resideo (Honeywell Home).
A service part rather than a whole assembly. The ball and the plate it seats on are the wearing surfaces; replacing them restores the action without changing what is connected to the pipe.
That is the whole argument for stocking it. Swapping the wearing parts is a bench job on a fixture that stays where it is; replacing the assembly means breaking connections that were sound.
Order against the assembly it came out of. Adaptor plates are cut for a specific body, and a ball that is right in every dimension but one does not seal.
