Wedge Gasket Seal

Wedge gasket seal is used on uPVC windows and doors to hold in the double glazed glass unit. You can find them installed both internal and external on pvc windows and doors. Over time wedge gasket seal can shrink, become hard and brittle causing it to break apart. If your wedge gasket seal starts to deteriorate you should replace them as soon as possible. We offer sample packs for all our gaskets so you can try each gasket before you buy. This ensures you choose the perfect fitting window or door gasket seal.
