Frequently bought together:


Reddiplex R4055 Bubble Flipper Gasket - for use on front doors, back doors and opening windows.

Please check your size carefully with the drawing.

  • This gasket is only available in black - no other colour is manufactured.

Flipper 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:
