Bifold Shower Seal - 8mm T-Head, 9mm Tall, Seals 4-9mm Gaps

What this seal is

A clear soft-PVC channel seal for bifold shower doors and bath screens, with a wide 8mm T-head that slides into the channel in your frame and a compact 9mm overall height that closes gaps of 4mm to 9mm. The flexible blade presses against the tray, bath or adjacent surface to keep water inside the enclosure.

Fit it horizontally along the bottom rail of a bath screen or shower door, or vertically on a glass upright to seal against tiles or a wall.

How to check it fits your door

Check the cutaway in the first photo against your old seal: the frame slot should be around 8mm wide, and the gap you’re closing between 4mm and 9mm. Several of our seals share this T-head width but differ in height, so it’s worth comparing the profile carefully before you order.

Specification

Why fit this seal

Stops leaks along the bottom rail. A hardened or shrunken channel seal is one of the most common reasons water tracks under a bifold door. A fresh blade closes the 4–9mm gap and protects flooring and skirting from water damage.

No adhesive, no mess. The T-head slides into the channel your old seal came out of — no glue needed, though you can add silicone if you prefer — and slides out again when next due a change.

Easy to cut at home. The soft PVC trims cleanly with household scissors, so cutting a 2000mm length down to your door width takes seconds.

Barely visible once fitted. The clear, translucent PVC keeps the glass looking frameless while quietly doing its job.

Fitting in three steps

1. Measure. Check the frame slot is around 8mm wide, measure the gap you need to close (4–9mm for this version) and the width of the rail or upright.

2. Choose. Pick 1000mm or 2000mm — whichever is at or above your measurement — or select a Custom Cut option for your exact length.

3. Fit. Slide out the old seal and clean the channel of soap residue, cut the replacement to your door’s width, then feed the T-head in at one end and slide the seal fully across.

Not sure it fits?

Email a photo of your old seal’s end profile or your measurements to sales@industrial-polymers.co.uk and our UK team will identify the right T-head width and height before you order — usually the same working day.
