For use on valve inlets, the new Swivel Joint (HSJ) will swivel UNDER PRESSURE! The primary application is on appliances that are placed on the ground, such as a manifold or ball valve. If the connecting large diameter hosed is twisted, there may be a tendency to flip the appliance over when water reaches it. The Swivel Joint will reduce or eliminate this possibility.
 
The HSJ can also be used on any valve or pump connection where the Swivel Under Pressure capability might be advantageous. It will swivel at any pressure up to the burst pressure of the hose.
