In ServiceUSE

Where it holds the line

Replacing legacy asbestos gaskets shouldn't mean compromising on performance, and SealGuard non-asbestos gaskets are engineered to match or beat the sealing characteristics operators remember — without the health and regulatory liability. A blend of aramid and mineral fibres in a heat-resistant elastomer binder delivers excellent hot-load retention and creep resistance, so the joint stays tight through thermal cycles. Every gasket is fully documented for compliance audits and asset-integrity records.

Typical applications

01Asbestos gasket replacement programmes
02Steam and thermal-fluid flanges
03Process and utility pipework
04Heat exchanger and vessel covers
05Valve and pump body joints
