B007 Bubble Gasket

The B007 is a bubble-style glazing gasket featuring a distinctive domed or curved "bubble" top section. This configuration compresses to establish a secure seal between the opening sash/leaf and the outer frame in compatible aluminium or uPVC window and door systems, minimising draughts, water infiltration, and noise. It is a push-fit gasket that slots into the specific groove of matching profiles, making it an appropriate replacement for seals that have deteriorated, stiffened, or failed to recover shape. Key specifications to determine fit: Gasket style: Bubble type with rounded/domed top (distinct from B003, B004, or other variants in exact dimensions; different from flipper gaskets with fins, wedge gaskets, or E-styles). Material: Extruded from durable TPE or PVC compound in black. Supplied lengths: Coiled rolls of 10 meters (for smaller tasks), 25 meters, or 50 meters. Profile matching: Groove dimensions and shape are unique to particular window/door systems. The B007 is compatible only with profiles designed for this exact bubble configuration. It is not universal and is not officially endorsed or tested by system manufacturers. Verification process: Measurements are system-specific. Compare directly to your existing gasket or use a sample matching service—supply a segment of the current seal for precise identification. Not suitable for: Profiles needing alternative gasket shapes or sizes (e.g., finned, wedged, or other compression designs). This gasket is suitable if your existing worn seal exactly matches the B007 bubble profile. Visual or sample comparison is required to verify compatibility.
