DeltaV-Seal™ Flange Gasket
The DeltaV-Seal is the tightest, safest and most durable flange gasket technology in the world. Designed to replace Spiral Wound and Kammprofile gaskets its fully metal design is robust and easy to handle, enabling a simple, gas-tight installation that is guaranteed to be maintenance-free for up to 10 years. Once installed the connection is non-ductile, static, and never requires re-tightening of bolts or fasteners to maintain tightness. Galvanic corrosion is also prevented by manufacturing the DeltaV-Seal from the same material as the connecting flanges.
We deliver in materials to match our customers’ requirements for both ASME B16.5 and EN 1092-1.

Other designs and applications
As our customer collects experiences from using our products, other innovative sealing solutions based on the gas-tight DeltaV-Seal technology are constantly developed. We meet special requirements from all sorts of industries every week. It is a wide spectre of challenging processes and all sorts of liquids and gases, but they all share the same challenge - leaking joints and failing gaskets.
DeltaV-Seal™ ST HX
Shell & Tube Heat Exchangers
The DeltaV-Seal™ ST HX has been developed to address the sealing challenges which are often associated with large Shell & Tube Heat Exchangers. It is made of one piece of metal, creating a robust seal used in U-Tube and Straight tube heat exchangers.
DeltaV-Seal™ AC HX
Air-Cooled Heat Exchangers
Sealing large air-cooled heat exchangers can be challenging, and are often prone to a lot of corrosion problems. To overcome this challenge, the DeltaV-Seal™ AC HX has been developed.
PHX for Plate Heat Exchangers
Sealing ISO G-type union connections typically used on plate heat exchangers can be challenging. To overcome this challenge, the DeltaV-Seal™ PHX has been developed.
