This is the rubber gromets used throughout Splitscreen and Baywindows wherever the steel brake lines pass through the bodywork. Normally 8 are required per vehicle.
Fits into any 14mm hole.
We've now sourced these from the Netherlands like previously. As the ones made in the UK are rock hard, and don't fit into the hole of the cross member like they should. These are the much nicer, softer version. They're a few pence more expensive, but they fit!
