Reddiplex R5019 Bubble Gasket - for use on front doors, back doors and opening windows.

Please check your size carefully with the drawing.


Bubble Gasket is used on a window or door to create a good compression seal when it closes - it goes between the opening part and the frame so that when the window / door is closed the gasket squashes helping the window/door to fit nice and snuggly.


What is the difference between a flipper gasket and a bubble gasket? Between all the different flipper or bubble gaskets the differences are simply shape and size - they both do the same basic job and cut down on draughts and cold spots. If you cannot see an identical gasket on our site then try the sample pack - many customer find that by trying the different gaskets in their window frames that they find a gasket suitable for the job.


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.

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.

    R5019 Bubble Gasket

    Perfect for my windows and doors. This is the best company I have found who supply so many different types of Gasket. My local company only had 6 to choose from and none really were an ideal fit. Excellent service but Royal mail let you down a bit. Thank you for covering all angles

    Reddiplex R5019 Bubble Gasket Double Glazing Seal

    Posted by John on Apr 16, 2022

    Refreshing to find a company able to provide a kit of samples and the right seal profile for my door. I paid a lot of money last time to a window company to fit the same thing. The service and communication were excellent but you were let down by Royal Mail who took five days to deliver the goods

    Although the glazing seal was not an exact copy of my original seal I am pleased to say it fitted fine. Prompt service and delivery. Highly recommended.

    It is what it says it is

    The right stuff was delivered, and on time. It was also easy to easy to apply - I wish I could say the same about removing the old seals! Obviously, the important thing is how long it will last before perishing, but I can't know that yet.

    What an excellent product. After years of draughts and noise from a patio door l found this company online. Ordered the sample pack to check what i needed then ordered the gasket. What i found was the original seals were not big enough to do the job had had flattened and lost their sqishiness (is there such a word?) The new seals were easy to insert and boy what a difference! No draughts and no traffic noise. The service was amazing from this company cannot rate them high enough. Very pleased. Would definately recommend buying the sample pack first.
