F006 Flipper Gasket

The F006 is a flipper-style glazing gasket characterised by a base section with a protruding flexible fin or lip. This fin compresses against the opposing surface to form a seal between the opening sash/leaf and the outer frame in compatible aluminium or uPVC window and door systems, helping to prevent draughts, water ingress, and noise. It is a push-fit gasket that inserts into the specific groove of matching profiles, serving as a replacement for original seals that have become brittle, torn, or ineffective. Key specifications to assess suitability: Gasket style: Flipper type with flexible fin (distinct from bubble gaskets with domed tops, wedge gaskets, or E-styles in shape and sealing mechanism). 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: Groove dimensions and fin configuration are unique to specific window/door systems. The F006 fits only profiles designed for this exact flipper style. It is not a universal replacement and is not officially endorsed or tested by system manufacturers. Verification process: Exact sizes are system-dependent. Compare directly with your existing gasket or use a sample matching service—provide a small section of the current seal for accurate identification. Not suitable for: Profiles requiring bubble, wedge, or other non-flipper gasket designs. This gasket is the correct choice if your worn seal matches the F006 flipper profile with its characteristic fin. Visual or sample comparison is essential to confirm fit before use.
