Resin Series push-to-connect fittings from ATP provide users with an easy method of connecting tubing. A secure connection is made by simply inserting the end of tubing into the fitting. TechniFit resin fittings have a working pressure of up to 150psi, and can be used with compressed air or inert gas. Push-to-connect fittings allow a quicker method of connection when compared to compression fitting or hose barb and clamp connections.
