The General Pump 90360800 is a genuine OEM replacement O-ring for General Pump plunger pumps and components. It measures 28.30mm x 1.78mm. O-rings seal the joints between pump parts, such as valve caps, manifolds, and fittings, and keep water contained under high pressure. Over time they harden, flatten, crack, or get nicked from pressure cycling, heat, chemical exposure, and routine service. That usually shows up as drips, seepage, or a loss of pressure. Replacing worn O-rings whenever you open the pump for valve or seal work restores a tight, leak-free seal and helps protect more expensive components. As a genuine General Pump part, it’s built for an exact fit.
