Black Universal Gasket


Universal Window and door gasket seal - also available in White
UPVC gaskets that can be used in many door and window situations. Easy to fit and simple to cut.

SOLD BY THE METRE - ** A typical door will need 6 metres **

The universal gasket is great for doors where the gasket seal has split or worn and a replacement cannot be found. This gasket fits 95% of UPVC doors and windows and can be used to stop draughts and water ingress.


Packing Advice: Due to its foam inners (rather than harder rubber) this gasket is very tricky to pack for postage and despite all our best efforts can become kinked in transit. We have found that once you unwrap and allow the foam inner to expand that the kinks lessen.


Available in both black and white to suit UPVC front and back doors.


Also good on interlockers on UPVC French doors.



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:

Frequently Asked Questions

You should order per meter and we will cut to length for you. As it is cut to length we cannot accept returns. If you are not sure which gasket you need then maybe try the sample pack first.

Whilst this is a good allrounder we cannot guarantee that it will fit your frame. We recommend purchasing our gasket sample pack to see which gasket fits in your frame the best.

Gasket can deteriorate and shrink over time so unfortunately we can’t identify your gasket this way. We recommend purchasing our gasket sample pack to see which gasket fits in your frame the best.

It is possible that a different gasket may work in your groove. Therefore, we have the sample pack, so you can try them and see what fits.

Generally by pushing bit by bit with your thumbs. With some of the chunkier gaskets such as wedge gaskets it can be done a bit easier with a gasket roller.

    Universal Door Seal

    Excellent. Thought I may have to replace my back door as it was very draughty but realised the seal had disintegrated in places and I couldn’t find a suitable replacement. This has worked perfectly. The lock is a little bit stiff now as this is slightly thicker than the previous seal, but not a problem and a lot cheaper than a new back door. Thank you.

    Black universal gasket

    Posted by Peter Smart on Aug 16, 2018

    I purchased this gasket to replace 10-year old gaskets on 2 sets of french doors and the door frames which allowed some serious drafts into the house last winter.. The old gaskets took some shifting and I ended up using some dental tools purchased on ebay for a couple of pounds to hook onto their nylon spines and prise out of the door and the doir frame grooves. Once done, the replacement gaskets went in incredibly easily with no tools required to fit, other than a pair of scissors to cut to length at a 45 degree angle. I subsequently blasted the closed doors from outside with my Stihl leaf blower and my other half told me nothing was getting through the seals, so hopefully sorted.
