Overview

Piston Lube Oil is the lubricant used on the pistons and plungers of a pressure washer pump, the component that generates the high pressure in the machine. The pump pistons run in the cylinder at high speed under full working pressure, and the lube oil keeps the piston and seal running cool and smooth while the machine is in use.

The listing carries the product name and the store code but no volume or specification. FLAGGED supplier verify for the bottle size and the oil specification before any figure is published. In a pressure washer the piston lubrication is one of the checks that keeps a pump alive: a pump run dry or on the wrong lube wears the pistons and seals quickly, and a piston rebuild is one of the more expensive repairs on a machine.

What You Need to Complete the Job

Frequently Asked Questions

What is piston lube oil used for?

It lubricates the pistons and plungers of a pressure washer pump, the parts that generate the high pressure. The oil keeps the piston and seal running cool and smooth under full working pressure, which is what keeps the pump alive on a machine that runs all day.

What size bottle is this?

The listing does not state the bottle size or the oil specification. FLAGGED supplier verify for the volume and the specification before any figure is relied on.

Why does the pump need its own oil?

A pressure washer pump runs its pistons at high speed under high pressure, so the piston lubrication is a separate service item from the engine oil. A pump run dry or on the wrong lube wears the pistons and seals quickly, and a piston rebuild is one of the more expensive repairs on the machine.
