TNN Engineering O-Ring (Single, for CNC Backings)

Nitrile (black)
Silicone (red)

Sold out

- Replacement O-ring to fit TNN CNC Backings, or as a buoyancy aid for small insects.
- Also fits Heatsink and Jitsie CNC backings.
- Available in standard NBR / Nitrile (black) material or Silicone (red) material, which is more resistant to chemicals and weathering.
- The silicone material is also slightly softer, allowing for easier installation and removal. This may mean a little more pad movement during use, which can give the brake a louder sound on initial appliaction.
- 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.

Questions

Andy

What are these O-rings for? I mean what function do they perform? And how are they supposed to be installed?

Hi Andy

The o-rings insert into a small cut out on the rear of the backing, which allows them to grip the 'pin' on the slave cylinders. Plastic backings use a pincer style 'clip' instead, as the material allows for this flexibility. It's not possible to replicate this with aluminium, so an o-ring is a simple, and effective alternative!

To install, carefully push the o-ring into the hole on the rear of the TNN backing, ideally getting it mostly located into the groove inside. You can then carefully work it fully into the groove using a very small screwdriver, or hex key. Make sure it's tucked in all the way around, inside and out! Once it's completely in the groove, run around the inside of it with a smooth hex key or screwdriver, to make sure it's seated fully. A drop of chain oil, or silicone lubricant, will help pad installation onto the slave cylinder.
