Product overview
Plug, 1/4-Inch MPT — an aftermarket drain plug / cap dimensioned to drop into Horizon circulation pumps without modification. In service it seals a drain or service port and is removed for winterizing or servicing. Replacement is routine: the threads and sealing washer wear, and plugs are frequently lost during winterization.
