The General Pump 701002 is a genuine OEM replacement O-ring that seals the valve cap on General Pump plunger pumps. It sits between the valve cap and the pump manifold, keeping water in under high pressure and preventing leaks around the valve chambers. The part measures .799" ID x .103" CS and is made from Buna-N (nitrile) rubber, which offers good resistance to water, oils, and many common cleaning solutions.
Valve cap O-rings wear from repeated pressure cycling and from being disturbed during valve service, so it’s good practice to replace them whenever you remove the caps to inspect or change valves. A fresh O-ring restores a tight seal and helps prevent leaks that can lead to pressure loss or manifold damage.
