Onan 130-0589 14 LB Pressure Cap Radiator / Coolant Fill Cap for Onan Generator Sets - New (NOS)

Onan Genuine Parts pressure cap, part number 130-0589, stamped 14 LB, in its original Onan box.

Application: Onan generator set cooling systems. The exact gen-set model coverage has not been verified on our end — the identification comes from the OEM part number printed on the original Onan Genuine Parts box and the 14 LB rating stamped into the cap.

Condition: New old stock (NOS). The cap is unused with intact sealing gasket and center valve, showing only light storage discoloration. The box is soiled and shelf-worn. The cap has not been pressure- or leak-tested.

Always match the pressure rating stamped on the cap to your engine's cooling-system specification. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase.
