MTM Hydro's Live 3/8" Stainless AG Swivel is a Premium Italian manufactured swivel. 'Live' refers to how this accessory will swivel while under pressure. The ability to do so is great when you are cleaning at distances greater than 25' and you need to spin the hose without rotating the entire gun assembly. The Live feature also allows you to uncoil your hose while under pressure and cleaning at the same time. With Higher GPM and PSI ratings, this Swivel was developed with professional contract cleaners in mind.
