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.

Exact fit for MPBZ20A model
Ordered the 20mm variant. Dimensions were spot on. Installation was straightforward. The self-lubricating aspect is a huge plus for keeping the maintenance schedule simple.
Q: Is the 40mm size suitable for saltwater environments?
A: Yes, the copper alloy material offers excellent corrosion resistance, making it suitable for both fresh and saltwater applications commonly found in mobile car washing.
Q: Does this bushing require additional grease or oil during installation?
A: No, this is a self-lubricating bushing with embedded graphite plugs. It is designed to operate without any additional external lubrication.
Q: Can I use this to replace a brass bushing in an older model?
A: In most cases, yes, provided the dimensions match exactly. The copper alloy is often more durable than standard brass. Please verify your specific inner and outer diameter measurements before ordering.
Q: How long is the warranty on these components?
A: We offer a 1-year manufacturer warranty against defects in material and workmanship under normal operating conditions.
Q: What is the maximum RPM these bushings can handle?
A: These bushings are rated for standard high-pressure pump speeds typically found in car washers, generally up to 3000 RPM depending on the specific load conditions.
