Black Shower Screen Seal - 8-10mm Glass, Seals 3-7mm Gaps

What this seal is

A black replacement seal for shower doors and bath screens fitted with 8–10mm glass — the right choice when a clear or white seal would look out of place on a dark-framed or matt-black enclosure. The rigid PVC U-section — about 12mm tall, with an 8mm mouth widening to a 10mm base — pushes onto the edge of the glass with no adhesive, and the soft hollow 7mm bubble beneath compresses against the tray or bath to close gaps of 3mm to 7mm.

This profile is most often fitted along the bottom horizontal edge of a bath screen or shower door, and works just as well vertically on the upright of the glass, sealing the gap between the glass and the tiles or wall.

Specification

Why fit this seal

Stops leaks and protects your bathroom. A worn, split or missing seal is the most common cause of water pooling outside the shower. Replacing it takes minutes and protects flooring, skirting and plaster from long-term water damage.

Matches black hardware. Black enclosures deserve a black seal — this profile blends with dark frames and matt-black fittings instead of standing out against them.

No adhesive, no mess. The U-section grips 8–10mm glass on its own — it pushes straight on and can be removed again without leaving residue on the glass.

Cut to fit at home. Order the next length up and trim it down for a perfect fit, or use our custom cutting service and it arrives ready to fit.

Fitting in three steps

1. Measure. Check your glass is 8–10mm thick, measure the edge you need to seal, and check the gap you are closing sits between 3mm and 7mm.

2. Choose. Pick the nearest length at or above your measurement — from 800mm up to 2500mm — or add custom cutting and we cut it to size before dispatch.

3. Fit. Trim to length if needed, then push the U-section onto the edge of the glass from one end and work your way along, so the bubble closes the gap. Never slide the seal along the glass — this can damage it.

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 length before you order — usually the same working day.
