Shower Door Brush Seal 7mm x 8mm for Bifold & Channel Doors

What this seal is

A brush seal for bifold and channel shower doors, combining a 7mm T-shaped backing for wider channel slots with an 8mm bristle pile below. The backing simply slides into the door’s channel — no adhesive — and the dense synthetic bristles sweep the tray as the door moves.

Because bristles flex individually, a brush seal conforms to slightly uneven trays and folds silently with the door — no squeak, no snag, and no folded-over blade like a worn PVC wipe.

Specification

Why fit this seal

Seals uneven gaps. Where a solid blade leaves daylight over a slightly uneven tray, hundreds of individual bristles follow the surface and close the gap along the whole run.

Silent, snag-free folding. Bifold doors drag their seal across the tray every time they fold — bristles sweep smoothly where a rubber blade squeaks, drags or folds over.

No adhesive, no mess. The T backing is held by the door’s own channel, so it slides in cleanly and can be replaced again in future without residue.

Sized to your gap. If 8mm isn’t quite right, the same 7mm backing carries 6mm, 10mm and 12mm piles — so you can match the brush depth to your door.

Fitting in three steps

1. Measure. Check the channel slot takes a 7mm backing, measure the gap beneath the door (around 8mm for this pile), and measure the channel length.

2. Choose. Pick 1000mm or 2000mm — whichever is at or above your channel length — and trim down for an exact fit.

3. Fit. Remove the old seal and clean the channel, cut the backing strip to length, then slide the T backing in until the brush runs end to end.

Not sure it fits?

Email a photo of your old seal — ideally showing its cut end — or your measurements to sales@industrial-polymers.co.uk and our UK team will confirm the right backing and brush depth before you order — usually the same working day.
