Bifold Shower Seal - 8mm Rigid T-Head, 14mm Tall, Seals 9-14mm Gaps

What this seal is

A clear channel seal for bifold and sliding shower doors, combining a rigid 8mm T-head with a soft 14mm sealing body that closes gaps of 9–14mm. The rigid head is deliberately stiff: it grips firmly inside the channel and won't creep along it in use, while the flexible body wipes the tray to keep water in.

It fits horizontally in the channel under the bottom rail of a door or bath screen, and works just as well vertically to seal between the glass and the wall. No adhesive is needed — the T-head slots into the existing channel, with silicone optional.

Which height do I need?

Check your channel slot takes an 8mm T-head (it may be very slightly narrower) and that your gap sits between 9mm and 14mm. We stock several heights of 8mm T-head seal — if your gap is outside that range, another height will suit better, and if you're between sizes, choose the larger for a tighter wipe.

Specification

Why fit this seal

Stops leaks under the door. A worn or missing channel seal is a classic cause of water pooling outside the shower — a new one takes minutes and protects flooring and skirting.

Stays where you put it. The rigid T-head grips the channel firmly, so the seal won't migrate along the rail as the door folds and slides.

No adhesive, no mess. It slides into the channel your door already has and can be swapped again just as easily.

Cut to fit at home. Trim the 900mm or 2000mm length to your door's width, or have us custom cut it before dispatch.

Fitting in three steps

1. Measure. Check the channel slot is 8mm and measure the gap you need to close (9–14mm for this profile).

2. Choose. Pick 900mm or 2000mm — whichever covers the width of your door — or our custom cutting service.

3. Fit. Remove the old seal, clean the channel, cut the new seal to size and slide the rigid T-head along the channel until fully seated.

Not sure it fits?

Email a photo of your old seal or your measurements to sales@industrial-polymers.co.uk and our UK team will confirm the right profile and height before you order — usually the same working day.
