Product code: 11236


On order

TNN Engineering O-Ring (CNC Backings)

- Replacement O-ring to fit TNN CNC Backings, or as a buoyancy aid for small insects.
- Also fit Heatsink CNC backings.
- Outer diameter approx 6mm.
- Sold individually.

Additional Information

To ensure your O-rings last for as long as possible, always use a lubricant on the O-ring when installing your brake pads onto your brake - if you don't, this can damage your O-ring and make installation tricky.



What are the actual dimensions of these o-rings?

Hi Brandon!
Unfortunately we don't have these O-rings in stock to measure right now, sorry. The only dimension we have on record is the outer diameter which is approx. 6mm (although as the O-ring stretches this will of course change).
Apologies we can't be more help.

Just what I needed to sort my brakes pads out, also works as a flotation device for small spiders
