Pre-Curved Shower Seal - 8mm Glass, Seals 15-20mm Gaps

What this seal is

A pre-curved replacement seal for curved shower screens and doors with 8mm glass. The rigid PVC U-section pushes straight onto the edge of the glass — no adhesive required — and the fin closes gaps of 15mm to 20mm between the curved glass and the bath, tray or wall, stopping water escaping every time you shower.

This seal is suitable for curved glass as long as your curve is continuous and your measurements are within the parameters detailed in the product diagram. If your glass is S-shaped, or straight and then curved, or falls outside those parameters, contact us and we can quote for a custom-curved seal instead.

Specification

Why fit this seal

Made for curved glass. Standard straight seals cannot follow the sweep of a curved screen — this seal arrives pre-curved so it hugs the glass and seals the full length of the edge.

Stops leaks and protects your bathroom. A worn or missing seal on a curved door lets water pool outside the enclosure; replacing it takes minutes and protects flooring, skirting and plaster.

No adhesive, no mess. The U-section grips 8mm glass on its own, so it pushes straight on and comes off cleanly whenever it needs replacing.

Cut to fit at home. The 850mm length trims down easily, or use our custom cutting service. Need it longer? We can quote for a custom seal made to your measurements.

Fitting in three steps

1. Measure. Check your glass is 8mm thick, measure the gap you need to close (15–20mm), and compare your curve against the measurements in the product diagram.

2. Choose. Order the 850mm length, or contact us for a custom quote if you need longer.

3. Fit. Trim to length if needed, then push the U-section onto the curved edge of the glass with the fin facing the gap. No tools, no adhesive, no drying time.

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 curvature before you order — usually the same working day. If your glass is S-shaped or straight-then-curved, we'll send you our simple measuring guide and quote for a custom seal.
