About the AirTAC PM
The AirTAC PM is a straight union that passes through a panel, held by a lock nut and rubber washer. Push the tube in to connect; press the release button and pull to disconnect. It works from vacuum (-750 mmHg) up to 1.0 MPa at -20 to +70 °C with soft nylon or polyurethane tube.
Available for Ø4, Ø6, Ø8, Ø10, Ø12 mm, in gray or black (D). The body and lock nut are aluminum alloy with an NBR rubber washer; the release button and chuck are POM.
