Re: Leaking Oberdorfer water pump

Gary is 100% correct about the process to remove the nipple without damaging the threads. But a bigger question is why are you using a threaded nipple instead of a barb fitting? I assume that you are connecting a hose...

A fiber gasket is the most convenient and quickest way to keep the oil from leaking/seeping.
An alternative way, increasingly popular within the automotive market, is to use automotive grade (black - Permatex, etc.) silicone-RTV, as a gasket substitute. Apply a bead of the silicone (aka: 'black death' or 'monkey crap') to the sealing surfaces, tighten down PART WAY (leaving "ONE thread loose"), let the silicone fully cure, then finish tightening after the silicone has become fully cured. Such silicone cures in the presence of atmospheric 'humidity' - so spritz/mist the assembled parts with water on the exposed silicone to accelerate the curing process.
