Pipe Swivels Appearance Pipe swivels are female adapters featuring a nut with a straight thread captured on a 30° cone tapered gland. A seal occurs between the taper in the male fitting and the 30° cone tapered gland. Pipe swivels are for use with male tapered pipe thread hose fittings with a 30° seat. Pipe Swivels do not seal on the thread like most pipe threads; they seal on the nose of the swivel and the seat of the male tapered pipe thread. This creates a metal-to-metal seal. Suggested Applications for Pipe Swivels As a hose adapter only. Other methods of connecting tubing, pipe, or joining components should be utilized in system design.
