Oil Pump O Ring Rebuild Kit - Nitrile - For Cast Iron Pumps

We now carry these convenient O-ring kits for when oil pumps are being rebuilt and/or disassembled. These kits include all three O-rings used in a big block Chrysler oil pump. The small thin one which seals the neck of the pump to the engine block, the small thick one which seals the oil passage from the pump body to the cover, and the large one which seals the rotor gears to the cover. Avoid oil leaks and blowouts with this easy to change and economically priced kit. These fit Melling and other similar style CAST IRON pumps, including standard, high pressure and high volume.
