Pusher Air Line is an Air Hose Assembly that you use on abrasive blasting equipment. The purpose of the Pusher Air Line is to supply compressed air to the abrasive metering valve. The Line uses reliable synthetic rubber. That synthetic rubber is suitable for both air and water (Wet Blasting). We carry the Air Line in many different lengths and widths. Also, we carry the Line in many different Inner and outer diameters. All Pusher Lines are rated at 200 PSI working Pressures. How is it made? We cut air supply hose to your specified length. Afterwards we add 2 swivel end inserts and 2 double bolt clamps to secure said inserts.
