12mm Thick Self-Adhesive EPDM Sponge Rubber Strip – Black Waterproof Closed Cell Foam Seal

This 12mm thick self-adhesive EPDM sponge rubber strip provides a flexible and reliable sealing, cushioning and protective solution for commercial, industrial, automotive and DIY applications.

Manufactured from compressible closed-cell EPDM sponge rubber, the strip offers excellent resistance to water, air, UV exposure, acids and general weathering. Its flexible sponge consistency allows it to compress around uneven surfaces, helping to create an effective seal while reducing noise, vibration and impact.

A strong self-adhesive backing is applied to one side for quick and convenient installation. Simply remove the protective backing and press the strip firmly onto a clean, smooth and dry surface. The product is supplied as a compact coiled roll for easy storage, handling and application.
