Engineered to prevent leaks
Engineered flange gaskets — from resilient spiral-wound to chemically inert PTFE — that seal bolted joints leak-free across the full temperature and pressure envelope.
A bolted flange is only as reliable as the gasket inside it. SealGuard gaskets are specified to the joint, not the catalogue: the right seating stress, recovery and chemical resistance for the exact flange class, medium and thermal cycle in front of you. Spiral-wound constructions soak up thermal movement and bolt relaxation, compressed-fibre and PTFE styles handle aggressive process chemistry, and every gasket ships with the standards traceability your inspectors expect — so the joint stays tight from hydrotest to turnaround.

Resilient metal-wound flange sealA precision V-section winding of 316L stainless and flexible graphite that recovers under bolt load and thermal cycling for leak-free flanged joints.
Tough fibre jointing for service flangesAramid-fibre and NBR-bound compressed gaskets that deliver dependable, economical sealing on general process and utility flanges.
Safe, certified asbestos replacementHigh-performance non-asbestos gaskets engineered as a like-for-like upgrade from legacy asbestos jointing, with full compliance traceability.
Conformable low-pressure elastomer sealElastomer flange gaskets in NBR, EPDM, FKM and silicone that conform to imperfect faces for reliable low-to-medium-pressure sealing.
Universal chemical-resistant flange sealVirgin, filled and expanded PTFE gaskets offering near-universal chemical resistance and high purity for the most aggressive flange duties.
Field-tested guidance from our engineers on specifying gaskets for demanding service.
Match gasket seating stress to the available bolt load and flange facing (RF, FF or RTJ) before selecting a style.
Use spiral-wound or kammprofile constructions where thermal cycling and bolt relaxation threaten joint integrity.
Specify PTFE or ePTFE fillers for strong acids, caustics and high-purity duties where graphite is unsuitable.
Confirm fire-safe certification (API 607 / 6FB) for hydrocarbon service flanges in classified areas.
A reliability problem in the field, closed at the joint — and the numbers that followed.
Case StudyA coastal refinery was failing fugitive-emission audits on high-temperature crude and vacuum-tower flanges, with repeated re-torques and unplanned isolation eating into availability. Thermal cycling was relaxing the incumbent sheet gaskets and opening leak paths on Class 600 joints.
We re-specified the worst-offending joints with 316L spiral-wound gaskets using a flexible-graphite filler and inner/outer rings, matched to each flange's ASME B16.20 geometry. Every joint shipped with a torque sequence, material certification and an assembly checklist for the turnaround crew.
The unit came back online and held leak-tight through the next two monitoring campaigns. Twenty-four months later the refinery has recorded zero reportable fugitive emissions on the upgraded joints and eliminated the re-torque cycle entirely.
Send us your service conditions — media, temperature, pressure and motion — and our engineers will specify the seal that holds the line.
