Durable and well-made

The build quality is excellent. The graphite plugs are evenly distributed. I bought the 30mm size for a commercial unit. It runs quieter than the original plastic bushing did.

Great for high-frequency use

We run our car wash station 10 hours a day. These bronze sleeves hold up incredibly well under constant friction and water exposure. No signs of wear after three months.

Solid performance

Good value for money. The copper alloy feels substantial. Only giving 4 stars because shipping took a bit longer than expected, but the product itself is top-notch.

Solved my squeaky pump issue

The noise from my pressure washer pump is completely gone. The graphite lubrication works immediately upon installation. Highly recommend for anyone needing a reliable bushing.

Perfect replacement for my pressure washer pump

My old bushing wore out after years of use. This copper alloy replacement fits perfectly and the self-lubricating feature means I don't have to worry about oil contamination in the water stream. Very smooth operation.
