0405R Replacement O-Ring – Motive 2-Quart Tank Pump

The Motive Products 0405R is the replacement pump-shaft O-ring used in Motive's most popular 2-quart Power Bleeder tank. When this O-ring wears or takes a compression set, the pump loses its air seal and pressure builds slowly or not at all. A fresh O-ring costs less than two dollars and restores full pump function in minutes.
