The Swivel Assembly is comprised of a female weld neck flange, a seal ring, a male fitting, a swivel ring flange, and a complete set of studs and nuts. In swivel flanges greater than 12”, ball bearing races are included to greatly ease the rotation of the swivel ring during installation. This connection
encompasses all of the features of a weld neck assembly but gives the ability to align boltholes with a simple rotation of the swivel ring.

A common problem with bolting up two opposing pieces of equipment is flange-to-flange bolt-hole alignment.  To cure this problem we offer a male connector with a swivel flange.  This allows you to rotate the bolt holes in the male swivel flange to align with the bolt holes in the female flange.
