Water Pump Housing Pipe Plug Kit

We carry a convenient NPT pipe plug kit, which includes all the pipe plugs which could possibly be needed for a water pump housing. Normally, two of the plug locations would be used for heater hose nipples, while the other two (one small and one large) would be used for temperature sending units. Whether you use the small or the large depends on the type of sending unit you are using. Usually the small temp sending unit is used for cars with temp gauges, while the large one is used for cars with idiot lights, however some aftermarket mechanical temp gauges also use the large port. So, we include every plug so that you'll have what you need, no matter what setup you are using. Use one kit per engine.
