The Halo Seal utilises proven Kammprofile technology to deliver high sealing integrity and low emissions
As the load is applied to the gasket, the soft facing material compresses and fills the grooves of the metal core.
THE HALO SEALING SYSTEM®
Leading Gasket Innovation
Kammprofile Technology
The facing material densifies at the peaks of the profile resulting in a series of very thin layers of high stress with outstanding tightness.

Revolutionary redesign of a metallic gasket
Reusable patented guide ring means lower costs and reduced inventory
Based on low emission, high integrity Kammprofile technology
Fire Safe Design HALO Sealing Systems
In the event of a fire it is critical that that the gasket is able maintain its seal and not release further supplies of flammable liquid.
The API 6FB fire test is designed to assess the fire safety of a gasket by measuring the leakage of gasket under fire conditions
Halo Seal has been tested to this standard and is certified as Fire safe
Benefits Of HALO Sealing System
The Halo Seal®
is an improved design of solid serrated-core gasket,comprising a unique two-part sealing system with an ‘interchangeable’ sealing element paired with a ‘split’ guide-ring. Due to this intelligent and flexible design, one Halo Seal® sealing element satisfies all pressure classes from 150psi to 2500psi, across the complete range of international flange standards; thereby providing a vast reduction in both capital and maintenance costs, in comparison to other metallic and spiral-wound gaskets
