A hose rotator includes a first coupling component and a second coupling component received in the first coupling component. The first coupling component is selectively rotatable with respect to the second coupling component. A release system is selectively disengaging a stationary rotational position of the first coupling component with respect to the second coupling component.

A pipe swivel assembly is provided including a body, an outer bearing, a stem, an inner bearing, and a locking collar, all annular about a central axis. The body includes a threaded socket and tapered throat. The stem includes a tapered nose and barrel section with a radial flange. The inner bearing is received in the socket and is trapped by the flange when the nose is at a predetermined distance from the throat. The outer bearing is trapped by the locking collar against the flange when the collar barrel is screwed into the threaded socket. A seal extends between an angled seat on the nose and an angled sealing surface of the throat. The stem can rotate around the central axis relative to the body without breaking the fluid tight seal between the stem and the body.
