Revolutionize your fill plant today! Our Push2Fill’s are in full operation at Butler Gas and according to them, it has reduced connection time on their fill rack from 10 minutes to 2 minutes. The Superior/Macro Technologies Push2Fill quick connectors are designed for fast, safe, and reliable connection of filling hoses to gas cylinders. The quick one push operation may reduce the possibility of carpal tunnel syndrome related to the twisting motion of hand-tight connections. The seal between the nipple o-ring and valve body is made by inserting the Push2Fill into the valve and locked into a pressure tight seal by simply pushing the locking sleeve forward. The Push2Fill lowers connection time and speeds the filling process. Can be converted to a “RPV” fixed pin version without having to buy a new Push2Fill.
