For use on valve inlets, the Harrington Full-Time Swivel (FTS) 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 hose is twisted, there may be a tendency to flip the appliance over when water reaches it. The Harrington Swivel Joint will reduce or eliminate this possibility. This product represents another example of our commitment to safety. The FTS 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. NOTE: To order the FTS on any part, add /FTS to part number. Call for pricing.
