Explanation of bubble and flipper gasket
Whilst bubble gaskets have a domed top with a profile that resembles a bubble, flipper gaskets instead feature a fin that runs the length of the gasket. Both work as seals when under compression between a frame and a closed window or door. Bubble-flip gaskets feature both characteristics, of bubble and flipper. These gaskets can become worn over time, but replacing them is quick and easy, the challenge can be getting the right gasket.
How to get the right gasket
Knowing the name of your window or door profile may help identify the gasket needed, as may comparing the following drawings to the profile of your existing gasket. Perhaps the most trusted method is to purchase a sample pack, and testing the samples in your actual gasket groove.
Did you know? These are made from a Thermoplastic Elastomers (TPE) material, a blend of plastic and elastic polymer. So they're durable, thermally efficient, with a core of polypropelene (PP), or PVC nitrile, to resist overstretch and expansion.
In this listing, you can choose a specific Bubble, Flipper, or Bubble-Flip gasket type and length, or a Sample Pack, which includes a 150mm (6in) piece of each type with profile sheet.
Fitting and Maintenance
Fitting Bubble and Flipper Seals
First, remove the original seal and clear away any debris. Then working from top centre of the frame, push the seal into the gasket groove. Do so all the way round the frame until back where you started. Ensure that the seal is not stretched in the process of fitting, as it will shrink back over time and create gaps and ineffective seal.
Looking after your Bubble Seal and Flipper Seals
To aid during installation, many seals are coated in a non-hazardous lubricant, which can be removed with warm soapy water. Subsequent cleaning should be done with soapy water. Avoid the use of household solvents as they can degrade the seals.

Rubber Wedge & 'E' Gasket for Windows and Doors
(Choice of type and length)
Seals draughty window and door units!
These gaskets are frequently paired, with 'E' Gaskets used on one side of the frame, and the Wedge Gasket on the reverse. They create a watertight and draught-proof seal between a window or door frame, and it's double-glazed unit or infill panel.
Replacing gaskets is quick and easy and requires minimal tools, and doing so can stop water ingress, eliminate draughts and noise, improve energy efficiency, safety and security.
Features & Benefits
Seals between double-glazed unit and frame

Durable core strengthens and resists overstretch

Explanation of Wedge and 'E' Gaskets
As their name suggests, Wedge gaskets are wedge shaped, so they can simply push into place between frame and double-glazed unit. They feature a rib that hooks onto the frame to keep it in place. Wedge gaskets are designed for easy fitting, and also easy removal, should a unit need to be changed, or 'E' gaskets replaced on the other side.
'E' Gaskets get their name from their profile, which can resemble the letter E, and are also referred to as Fir Tree gaskets because they resemble the downward slopping branches of a fir tree. A mushroom extrusion that runs along these gaskets is pushed tightly into a groove in the profile. Then under compression against the double-glazed unit, the branches of the fir tree create multiple seals.

Fitting and Maintenance
Fitting Window and Door Wedge Gasket
Wedge gasket seals are normally fitted in four pieces, with mitred ends for a neater seal. There will be a piece for each side of the unit, as well as one for both the top and bottom.
When replacing Wedge gaskets, it's important that you only replace one piece at a time, so that the beading on the other side and the glazing remain secure. Start by levering out the end of a seal, taking care that you don't damage the frame. Once the end if free, you should be able to remove the rest of the seal by hand.
Cut replacement wedge gasket 5% longer than measured, to allow for any shrinkage of the gasket over time. To fit, just position one end tight into the corner and push down between frame and glass/panel along its length to the opposite corner.
Fitting Window and Door 'E' Gasket
'E' Gaskets are clipped into the frame or bead, which makes them the most challenging to replace. Removal of the old gasket and fitting of the new, usually requires removal of the beading and sometimes also the glazing.
If the frame uses a combination of Wedge and 'E' gasket, then removing the Wedge gasket first will allow the beading to be more easily removed. When removing beading, take great care to avoid snapping or cracking, as sourcing replacement beading can be very difficult. Long beads will flex more than short beads, so remove those first. A fairly stiff wallpaper scraper of 4-5 inches can be used; just position half way along the bead, between bead and frame, and lever off. The first bead can be difficult, but the remaining beads will be easier.
When putting beads back, start with the shorter beads, and finish with the longer ones. A rubber hammer can be used to knock the beads back into place.
Please note that many modern frames have coextruded gaskets, which are welded to the frame or bead. Some are welded to an old profile, which still has the gasket groove. In such a case, a replacement gasket can be fitted to the unused groove.
A Gasket Roller can greatly speed installation of wedge gasket, and Mitre Shears help to create clean mitred cuts.
Looking after your Wedge and 'E' Gaskets
To aid during installation, many seals are coated in a non-hazardous lubricant, which can be removed with warm soapy water. Subsequent cleaning should be done with soapy water. Avoid the use of household solvents as they can degrade the seals.

Gasket may flatten over time or become damaged, and the rubber can become brittle, and shrink. All these things will affect the seal around the door, and likely lead to draughts, heat loss, water ingress and noise. Fitting new gasket is an easy, low-cost solution, that can seal your door like new, or even better, as some gaskets designs have been improved.

Standard thresholds only. Low thresholds use/require a brushpile.
PAB633 is often preferred to PA275 for use on threshold, as its crescent moon shape helps prevent gasket from being pulled out.
AB268 is preferred to AF244 for enhanced weather performance, but can create too much friction for new installations.

Fitting Advice
Fitting bi-fold door bubble and flipper gasket
Bubble and Flipper compression seals are really easy to replace; just pull out the old, and after clearing away any debris from the gasket groove, push in the new. You should typically start top centre, and work round the sash or frame, whilst taking care not to stretch the gasket. If fitting PAE275 bubble gasket to a sash, the semi-rigid AE272COR-ABC corner moulds should be used, with the bubble gasket cross cut between them.
Fitting bi-fold door wedge and ‘E’ glazing gasket
Wedge gasket seals are normally fitted in four pieces for each edge of the glazing, with mitred ends for a neater seal. Replace one piece at a time, so that the beading on the other side and the glazing remain secure. Lever out the end of existing seal, and then remove the rest by hand. Take care to not damage the frame. Cut replacement wedge gasket 5% longer than measured, to allow for any shrinkage over time. To fit, just position one end tight into the corner and push down between frame and glass/panel along its length to the opposite corner.
‘E’ Gaskets clip into the frame, so usually require removal of beading and sometimes also the glazing. If glazing combines Wedge and ‘E’ gasket, then removing the Wedge gasket first will ease removal of the beading. Long beads will flex more than short beads, so remove those first. A fairly stiff wallpaper scraper can be used; just position half way along the bead, between bead and frame, and lever off. The first bead can be difficult, but the remaining beads will be easier. Take great care to avoid breaking beads, as sourcing replacement can be difficult. When putting beads back, start with the shorter beads, and finish with the longer ones. A rubber hammer can be used to knock the beads back into place.
Please note that many modern frames have coextruded gaskets, which are welded to the frame or bead. Some are welded to an old profile, which still has the gasket groove. In such a case, a replacement gasket can be fitted to the unused groove.
