Good quality, fast shipping

The bronze alloy feels very durable. I ordered the 40mm length and it installed easily. Took off one star only because the packaging was a bit battered, but the part itself is fine.

Great value for money

Compared to OEM parts, this is a fraction of the cost but performs just as well. The graphite inserts are clearly visible and well-seated. Will buy again.

Solved my leakage issue

My pump was leaking due to a worn-out liner. Replaced it with this graphite bushing and the seal is perfect now. The oil-free design keeps things clean.

Solid construction

Very heavy and well-made. It took a little effort to press fit into the housing, but that speaks to the tight tolerances. Working perfectly after a week of daily use.

Perfect fit for my pressure washer pump

I needed a replacement bushing for my commercial car wash unit. The dimensions were exact, and the self-lubricating feature works great under high pressure. No more squeaking noises.

Excellent for heavy duty use

We use these in our fleet of mobile car cleaning vans. They hold up much better than the standard plastic liners we used to buy. Highly recommend for professional use.

5 FAQ

Q: What is the tolerance on the 35mm inner diameter?

A: The inner diameter is machined to an H7 tolerance class, ensuring a precise fit for standard 35mm shafts used in most pump assemblies.

Q: Does this come with the graphite plugs pre-installed?

A: Yes, the MPBZ series comes with solid graphite plugs already embedded in the copper alloy matrix for immediate self-lubrication.

Q: Do I need to apply grease during installation?

A: No additional grease is required. The self-lubricating nature of the graphite means you can install it dry, though a light film of oil can help with the initial press-fit.

Q: Can I use this with hot water pressure washers?

A: Absolutely. This copper alloy liner is rated for temperatures up to 250°C, making it suitable for both cold and hot water car washing applications.

Q: Is the 60mm length available in stock?

A: Yes, all length variations including 20, 30, 40, 50, and 60mm are currently in stock and ready to ship.
