Automotive silicone foam seal strip

This 17 mm diameter silicone rubber strip is sold as a one-metre length for sealing gaps in automotive, electronic and industrial assemblies. The soft, high-density foam compresses to fill irregular surfaces while resisting aging and weathering. It suits mechanics, technicians and DIY users who need a pliable, long-life cord for custom gaskets or insulation.

Simple push-fit installation

The strip has no adhesive backing, so it is pressed into channels or wrapped around joints and held by friction or external clips. A common issue is over-stretching the foam during fitting, which reduces its recovery and can leave permanent gaps. Cutting the 1 m length with a sharp blade prevents frayed ends that leak.

Stable sealing from -50 °C to 250 °C

The material retains elasticity across a wide temperature span, staying flexible in deep cold and resisting softening or cracking under sustained heat. Under continuous compression the foam maintains its seal without taking a permanent set, making it reliable for long-term service in engine bays, enclosures or pipework.
