Easywash 365+ Professional Wash Gun With RM Suttners Patented Low Trigger Force technology. The engineering team at RM Suttner are always looking to develop their products to make high pressure cleaning more effective and efficient. The low trigger force technology in the Easywash365+ guns makes handling of the gun very easy for the user. The range of Easywash365+ products have been designed specifically for the professional car wash bay. This wash gun also features a weep valve, the idea behind the weep valve is to allow a small amount of water to continue to pass through the gun even when the trigger is not actuated. This continuous movement of water through the piping, hose and spray device significantly reduces the liquids ability to freeze. This gun has a swivel inlet and outlet.
