0007.43 OIL SEAL

SKU: 6083

Oil seal 0007.43 is a crankcase-side seal for plunger pumps — the ring that seals the passage where the drive components meet the oil reservoir, retaining oil while excluding water and contaminants. A failed oil seal lets oil escape or water in; water in the oil turns it milky and quickly degrades lubrication for bearings and the drive mechanism, so this is not a part to run on borrowed time. Replace oil seals as a set and always with fresh oil. Fitment is by part number: confirm 0007.43 on your pump's exploded parts diagram or data plate before ordering.
