Here is the place to find help selecting the gasket you require.

Take a look at the main gasket types below and click on the image that best describes your gasket.

 

Image of Wedge Gasket

Wedge Gasket

This gasket is usually fitted to the inside of the frame and is inserted in the gap between the glass unit and the window frame. The gasket is designed to push the glass unit forwards so that the external part of the glass unit makes a weather-tight seal against the external E gasket. It also locks the external bead into a channel thus preventing the beads from being removed from the outside. It is still possible to remove the external bead on older systems and if you have one of these types I would recommend you exchange the wedge gasket for security glazing tape. Using this tape means the glass is sealed into the frame so even if the external beads are removed, the glass can not be removed from outside. In the example image, the "gap" filling dimension is 5.2mm and the width of the throat is 5.2mm. Try to measure your gasket and select the closest one from our range. If you are still unsure about what wedge gasket to order then you could use our sample service to order a selection of gaskets to try before you buy. This is a good idea if you are buying large quantities of gaskets as these goods are non-returnable due to being cut to size from large drum quantities.

This gasket is used to create a weather seal between an opening vent / door and a fixed frame.The gasket pushes into a groove in the frame and should be tight enough to hold firmly when pulled. Bubble gaskets come in a variety of bubble heights and foot widths. In the example image, the bubble height is 5.5mm and the foot width is 5.8mm. The bubble is slightly offset to the foot so note what yours is like when selecting your replacement gasket. Some bubble gaskets also have an additional fin off to one side. If you are unable to match your bubble gasket with fin then try using a standard bubble gasket, it will probably be fine. Try to measure your gasket and select the closest one from our range. If you are still unsure about what wedge gasket to order then you could use our sample service to order a selection of gaskets to try before you buy. This is a good idea if you are buying large quantities of gaskets as these goods are non-returnable due to being cut to size from large drum quantities.

This gasket is generally fitted to the glazing beads or to the fixed frame and forms part of the glazing seal (the rubber that touches the glass). Like the bubble gasket, it has an arrow shaped foot that pushes into a preformed groove in the frame and should be tight enough to hold firmly when pulled. In the example image, the foot size is 5mm and the effective gap filling size is 4 mm. The foot size varies depending on the groove size and location within your frame as does the effective gap filling dimension. It is not always necessary to replace your gasket with one of the exact same design. Provided the foot size is correct and the effective gap filling size, the design or shape of the gasket can vary. In the example, the longer vertical fin to the far left is the part of the gasket that you can see once it is fitted. This is the part the forms a seal between the face of the glass and the frame / glazing beads. In some E gaskets, this fin can be large or small in height. It doesn't really matter what size it is providing it makes a good seal. There are a few exceptions

 Flipper Gasket

This gasket does the same job as bubble gasket and in most cases either bubble gasket or flipper gasket can be used in the same location. Like the bubble gasket, it has an arrow shaped foot that pushes into a preformed groove in the frame and should be tight enough to hold firmly when pulled. In the example image, the foot size is 5mm and the effective gap filling size is 6.4 mm. The foot size varies depending on the groove size and location within your frame as does the effective gap filling dimension. It is not always necessary to replace your gasket with one of the exact same design. Provided the foot size is correct and the effective gap filling size, the design or shape of the gasket can vary.
