Rubber and sponge cord, also known as 'rubber rope' or 'sponge rope', serves as a versatile sealing solution when a precise moulded O-ring size is unavailable. Henry Gallacher offers a comprehensive selection of rubber cords crafted from EPDM, neoprene, nitrile, silicone, and Viton® 'A'. Our standard rubber cord diameters range from 1mm to 40mm*, suitable for diverse sectors including automotive, aeronautical, chemical, electrical, environmental, petrochemical, and food and pharmaceutical industries. Custom diameters, coil sizes, rubber compounds, and scarf jointed vulcanised O-rings are available upon request.
Our closed cell sponge cords come in neoprene and silicone variants, each offering distinct benefits. These materials are notably more compressible and flexible than traditional rubber cords, making them ideal for both internal and external applications. Silicone sponge cords are frequently used for high-temperature seals in ovens and doors, electrical seals outdoors, and seals in food processing equipment. Neoprene sponge cords provide effective sealing against gas, liquid, and dust leakage during machinery operation and serve as a practical alternative to foam backer rods.
We can manufacture a wide range of other materials and sizes tailored to your specific requirements.
