What you get

One complete 30mm double seal set — upper and lower seals with the 44 x 57 stationary seats. Aftermarket replacement, built to OEM-equivalent standards or higher. O-rings, lip seals and gaskets are sold separately. If you are rebuilding the pump, order the oil chamber parts at the same time so the unit goes back together in one go.
