(6mm-3m) EPDM Foam Weather Seal Strip, 6mm X 3m for DIY Gasket

• [Diameter Options] Available in three precise thicknesses — 3mm (for hairline cracks and window sash gaps), 6mm (for standard door frames and cabinet edges), and 8mm (for larger expansion joints, pipe penetrations, or heavy‑duty waterproofing). Each roll is 3 metres long. Choose the diameter that matches your gap width (recommended compression ratio 25‑50%) for optimal airtightness without over‑compressing the foam.
• [Compression Seal] The solid round cord relies on mechanical compression to form a tight seal – simply press it into gaps, channels, or grooves, and the natural resilience of the EPDM foam expands to fill uneven surfaces.
• [Closed‑Cell Foam] Extruded from high‑density EPDM synthetic rubber, this cord withstands temperatures from -40°C to +120°C, UV radiation, ozone, and humid conditions without hardening, cracking, or losing elasticity. The closed‑cell structure prevents moisture absorption, stopping mould and rot even in persistent rain or high‑humidity environments.
• [Repeated Resilience] The foam achieves a unique balance between flexibility and firmness – soft enough to conform to irregular surfaces, yet dense enough to maintain consistent outward pressure against the mating face. This ensures a reliable seal even with repeated opening and closing of doors or hatches, as the cord returns to its original shape after every compression cycle.
• [Versatile Use] Can be used as a soft bumper pad for cabinet doors to reduce impact noise, as a vibration‑damping layer under heavy equipment, or even as a creative material for model making, jewellery display lining, or pipe insulation. The neutral black colour blends seamlessly with most industrial and home environments, while the non‑abrasive surface protects delicate surfaces.
