Explore our patented metal-to-metal sealing technologies. Designed to deliver leak-free, reliable performance in the world's most demanding environments.
Both Taper-Lok® and CofferLok™ connector systems are custom-adapted to serve critical operational requirements across major industrial sectors.
Underwater pipeline, riser, and swivel systems engineered to handle extreme depths, high pressures, and dynamic loads without leakage.
Explore Subsea Applications
Zero Gap metal sealing connectors built for refinery reformers, hydrotreaters, LNG terminals, and high-pressure hydrogen service.
Explore Petrochemical
High-pressure tubesheet and channel cover joints that eliminate cracking welded diaphragms, saving significant maintenance downtime.
Explore Exchanger ClosuresThe industry standard for high-integrity bolted metal-to-metal sealing. Featuring self-energizing flanges that use a wide-area seal geometry—the connection actually tightens as internal pressure increases.
High-integrity compact flanges built to withstand severe process lines, reducing flange weight by up to 75% compared to standard ASME flanges.
Explore Compact Flanges
Features a rotating outer ring that enables fast alignment of bolt circles, ideal for subsea flowlines and restricted access headers.
Explore Swivel Flanges
Specialized spherical-nose flanges designed to accommodate up to 10 degrees of angular offset without pressure de-rating.
Explore Misalignment
High-integrity blind closures and nozzle end caps providing pressure-assisted, zero-leak containment for piping terminations.
Explore Blind Closures
Self-energized, wide-area metal-to-metal seal rings offering 20x the contact area of standard seals, engineered for repeated maintenance cycles.
Explore Seal RingsEngineered for applications where space and weight are at a premium. CofferLok clamp connectors offer the same zero-leak reliability but with a 4-bolt footprint and up to 80% weight savings over conventional flanges.
Our patented 4-bolt external clamp assembly designed to replace heavy multi-bolted flange connections with up to 80% weight reduction.
Explore Clamp Assemblies
Precision-forged weld neck hubs designed for butt-welding directly into piping spools, featuring self-centering pockets.
Explore Weld Hubs
High-pressure rapid-access closures designed to terminate piping lines or manifolds with quick-release 4-bolt clamp actions.
Explore Blind Closures
Fully reusable, pressure-energized taper sealing rings that provide gas-tight metal-to-metal joints, completely eliminating gasket relaxation.
Explore Seal Rings
Offshore topsides and hull piping connectors saving up to 80% weight over conventional ANSI/API flanges on FPSOs and platforms.
