Incremental Wedge Gaskets

Incremental Wedge Gasket

Glass rattling or wedge gasket loose? Incremental wedge gaskets come in graded sizes, so you can choose the step that fits your glazing gap.

We stock Reddiplex TPR incremental wedge gaskets in graded sizes (such as R6503 and R6505), sold per metre, and an incremental wedge sample pack.

How to Match Your Wedge Gasket

Take out a short piece

Pull a short length of the old wedge gasket out from between the glass and the bead, and look at the end.

Measure the gap

Measure the gap between the glass and the glazing bead. This sets the thickness you need.

Compare the R-number

Compare your piece with the product diagrams. Reddiplex profiles are listed by R-number.

Use a sample pack

If several profiles look similar, test them in the frame with a sample pack first.

Wedge Gasket Guide

Why Incremental Sizes?

The gap between glass and bead varies between windows. Incremental profiles step up in size, so you can pick the one that grips firmly without being too hard to push in.

How to Fit Wedge Gasket

Start at a corner and push the gasket into the gap between the glass and the bead, working along each side. Don't stretch it, or it will shrink back and leave gaps at the corners. Leave a little extra and trim neatly.
