The standard Taper-Lok® connection is a compact flange with wide area seal and is made up three components, the seal ring, a male and a female flange.  The design is made up of two converging angles based on the wedge principle.  The male nose is comprised of a 20° angle while the female contains a 10° pocket.  The Taper-Lok® seal ring, with comparable angles, sits in between the flange components and acts as a “door stop” by creating a wedge.  The Taper-Lok® flanges are self energized and require less bolt loads than standard connections. The seal ring is generally made of the same material as the flange and is reusable.

Standard Taper-Lok® connection sizes range from 1/2" to 83" with varying wall thicknesses, sealing pressures up to 40,000 psi, and temperatures ranging from -350º to 1600º F.  The standard connection is the driving premise for all other Taper-Lok® connections.
