Silicone foam rubber sealing strip — 3 metres of high-density, smooth-exterior sponge for reliable sealing and cushioning Key benefits Effective sealing and cushioning: Compressible silicone foam closes gaps and reduces vibration while providing a soft, durable seal. Long-lasting shape retention: Low compression set and anti-compression construction preserve thickness and performance after repeated or sustained loads. Versatile fit: Supplied in a 3-metre length and available in multiple cross-section sizes (example: "2mm x 10mm" = thickness x width) to suit a range of joints and edges. Main features Material: Foam silicone rubber with defined hardness, high density and a smooth outer surface. Length and sizing: 3 metres total per supply; available in various thickness × width profiles so you can choose the right seal for your gap. Performance: Maintains cushioning and sealing ability even under heavy load or prolonged compression, minimizing deformation over time. Why you need it Prevents drafts, dust and minor water ingress by filling gaps where rigid seals fail. Protects surfaces and components from impact and vibration without hardening or cracking. Provides consistent performance in applications that require repeated compression and recovery. Typical applications Door and window sealing: Close gaps around frames to reduce drafts and rattles without changing door alignment. Equipment and enclosure gasketing: Cushion panels, doors or lids on appliances, cabinets and electronic enclosures. Automotive and marine trim: Seal and protect seams, lids or trim pieces where a compressible, durable foam strip is needed. What’s included 3 metres of silicone rubber sponge sealing strip in the selected cross-section size (thickness × width). Notes on selection Choose the cross-section size that matches the gap width and required compression. Example sizing format: "2mm x 10mm" means 2 mm thickness by 10 mm width. This silicone foam sealing strip is designed to provide durable sealing and cushioning where long-term compression resistance and a smooth, high-density foam surface are required.
