Black Bifold Shower Seal - 5.5mm T-Head, 17mm Tall, Seals 12-17mm Gaps

What this seal is

A black channel seal for black and dark-framed bifold enclosures with a 5.5mm channel slot. The T-shaped head slides into the aluminium or plastic channel on the door — no adhesive needed — and below it a large hollow oval bulb gives the seal its 17mm height, squashing gently against the bath or tray to close gaps of 12–17mm.

Fit it horizontally under the bottom rail of a bath screen or shower door, or vertically on the glass upright, and it stops water escaping every time you shower — while matching the black frame instead of standing out against it.

Specification

Why fit this seal

Stops leaks under the door. A hardened or split bottom seal is the most common reason water ends up outside a bifold enclosure. The soft hollow bulb compresses against the bath or tray, closing the 12–17mm gap and keeping the water where it belongs.

Matches black enclosures. Made in black to suit black-framed and matt-black enclosures — no mismatched clear strip against a dark frame.

No-mess fitting. The T-head simply slides along the existing channel — no adhesive, no tools, no drying time.

UK stock, fast dispatch. Held in stock in the UK and dispatched same working day when ordered before 2pm.

Fitting in three steps

1. Measure. Check the channel slot is around 5.5mm wide, measure the gap you need to close (12–17mm) and the width of the door.

2. Choose. Pick the 1000mm or 2000mm length — whichever is at or above your door width — or have us custom cut it.

3. Fit. Remove the old seal, clean the channel, trim the new seal to size, then slide the T-head along the channel until 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.
