This ACME-style connector from Fastest uses SlideMate technology to facilitate quick connections for motor fuel/forklift and bulk bobtail tank filling applications. FasFuel also features a full-flow design to ensure maximum flow rate while in operation. Upon disconnect, the connectorís internal shut-off valve minimizes the amount of propane venting into the atmosphere (less than 4cc). Stainless steel parts and components optimize connector performance in adverse weather conditions.
