Taper-Lok® Connectors

Bolted Compact Flanges

The industry-leading bolted connector utilizing self-energizing wide-area metal seal rings to eliminate emissions.

Why Choose Taper-Lok® Flanges

Standard ANSI flanges depend entirely on gasket compression, which relaxes over time due to thermal fluctuations and pipe vibration. Taper-Lok® uses a tapered contact surface where pressure actively pushes the seal ring tighter.

With an extremely compact face profile and a lower bolt count, Taper-Lok® reduces piping layouts and allows systems to be built closer, saving structural steel and engineering costs across process plants and marine manifolds.

Taper-Lok FAQ

Are Taper-Lok® flanges approved under ASME codes?
Yes. Taper-Lok® compact flanges are fully qualified and comply with ASME Section VIII Division 1 and 2 standards for pressure vessel components, and comply with international piping standards.
Does Taper-Lok® offer a leak-free guarantee?
Taper-Lok® compact flanges establish a gas-tight, zero-leak boundary. Because the metal-to-metal sealing ring has a massive contact surface area, it prevents fugitive emissions and keeps process lines leak-free.
What temperatures can Taper-Lok® connectors handle?
Taper-Lok® connectors are qualified to handle services ranging from cryogenic temperatures (LNG duty) all the way up to 1,500°F (815°C) in high-temperature petrochemical lines.
