Bubble-Bead Bifold Seal - Reversible 2mm/5mm Bead, Seals 14-19mm Gaps

What this seal is

A clear soft-PVC seal for folding bath screens and shower doors that is held in the frame by a round bubble bead instead of a T-head. The bead is reversible — one end is 2mm, the other 5mm — so a single seal fits two different channel sizes. Simply slot the matching end into the groove; no adhesive is needed.

The tall 19mm body is made for the larger clearances under bifold doors, closing gaps of 14–19mm that ordinary channel seals cannot reach.

How to check it fits your door

Look for a small round groove in your frame — rather than a T-slot — around 2mm or 5mm wide, with a 14–19mm gap below it. Compare your old seal against the cutaway in the first photo; if your groove matches either bead size and your gap is in range, this is the right profile.

Specification

Why fit this seal

Closes big gaps under folding doors. A hardened or missing bifold seal lets water stream out under the door. With its 19mm-tall body this profile bridges 14–19mm clearances and keeps the water inside, protecting flooring and skirting.

One seal, two channel sizes. The reversible 2mm/5mm bead means you don't need to identify your groove size perfectly before ordering — whichever end fits your frame, use that one.

No adhesive, no mess. The bead simply slides along the groove in the frame; the old seal slides out just as easily, with no glue or residue.

Easy replacement. The soft PVC trims with household scissors and fits in minutes.

Fitting in three steps

1. Measure. Measure your frame's round groove (around 2mm or 5mm), the gap below it (14–19mm), and the width of the door edge.

2. Choose. Pick the 1000mm or 2000mm length at or above your measurement, or add custom cutting and it arrives ready to fit.

3. Fit. Remove the old seal and clean the channel groove. Choose the bead end that matches your groove, cut to length, then slide the bead along the groove until the seal runs the full width.

Not sure it fits?
