What Are Foam Gaskets?
Foam gaskets are sealing products manufactured from flexible cellular materials that compress under load to create a reliable seal. Unlike solid rubber gaskets, foam gaskets offer greater compressibility, making them ideal for applications where surfaces may be uneven or where vibration and movement occur.
Foam gaskets are commonly used to:
- Prevent dust ingress
- Seal against moisture
- Reduce vibration
- Dampen noise
- Improve thermal insulation
- Create air-tight seals
- Protect sensitive components
They are widely used throughout industrial manufacturing, automotive, HVAC, electrical and electronic sectors.
Custom Foam Gasket Manufacturing
Stephens Gaskets manufactures bespoke foam gaskets from customer drawings, CAD files, specifications and samples.
Our foam gasket manufacturing services support:
- Prototype development
- Low-volume production
- OEM manufacturing
- Replacement components
- Custom sealing solutions
Whether you require simple strips, complex profiles or intricate gasket geometries, our manufacturing capabilities ensure precise and repeatable results.
