TW023 Wedge Gasket

The TW023 is a wedge-style glazing gasket with a tapered or arrowhead-shaped cross-section designed to secure and seal glass panels in aluminium or uPVC window and door systems. It positions between the glazing bead and the glass edge, acting as a buffer to prevent direct glass-to-frame contact, while providing cushioning, stability, and a weather-tight seal. It is a push-fit gasket used during glass installation or replacement when original wedges are damaged, flattened, or displaced. Key specifications to assess suitability: Gasket style: Wedge type (distinct from SYS1, SYS2, SYS4 or other wedge variants in exact dimensions; different from bubble gaskets with domed tops for sash-to-frame sealing, flipper gaskets with fins, or E-gaskets with multi-leg designs). Material: Extruded from durable TPE or PVC compound in black. Supplied lengths: Coiled rolls of 10 meters (ideal for smaller repairs), 25 meters, or 50 meters. Profile matching: Dimensions and shape are specific to particular glazing beads and profiles. The TW023 fits only systems designed for this exact wedge configuration. It is not universal and is not officially endorsed or tested by system manufacturers. Verification process: Exact sizes vary by system. Compare directly with your existing gasket or use a sample matching service—provide a small section of the current wedge for accurate identification. Not suitable for: Sash-to-frame sealing (use bubble/flipper/E types instead) or profiles requiring different glazing methods. This gasket is the right choice if your glazing system uses a matching TW023 wedge profile for beading. Visual or sample comparison is essential to confirm fit before use.
