3mm Wedge Compression Back Gasket

3mm Wedge compression back gasket

  • This gasket is only available in black.    

Wedge gasket is fitted between the double glazed unit and the upvc frame to hold the glass securely in place. Over time these gaskets can shrink or perish and create gaps which lets in draughts and cold spots. It is important to get the right size of gasket as too thick will put too much pressure on the glass (if you can even get it in) and too thin will not hold the glass tightly. It is more often found on externally beaded windows as it works together with the bead to push the glass into place and create a secure fit.

When fitting wedge gasket you can push into place using your fingers or if you are doing quite a large area you may find a gasket roller better to use. Gasket rollers are available on our site by clicking here


 As gasket is custom cut to the individual requirements we cannot accept returns.  If you are unsure which gasket you need then please use our gasket sample pack:

    The customer service team were very helpful when I had a query. The order arrived very quickly and was easy to fit. No one locally stocked the gasket so decided to buy online, the dimensions / pictures were extremely helpful. Thank you.

    Great Gasket

    Posted by Les Orrin on 21st Jan 2013

    The product arrived within 36 hours. Very easy to replace the old originals I would recommend that the packet of samples is purchased first in order that the correct item is ordered. I fitted approx 12 meters in just over the hour and it has made quite a difference.

    Exceelant Product

    Posted by Charles Patterson on 10th Jul 2012

    Purchased sufficent to do a window as a trial as the gaskets had gone hard. Found the product fitted perfectly and was easy to install. Will purchase a bucket full to replace all the gaskets on windows that must be at least 25 years old.
