Series 7138 is a flexible air conduit that connects the remote hand control to the dispenser control valves in abrasive material blasting systems. When the hand trigger is disengaged, the delivery system immediately shuts down, mininimizing uncontrolled high velocity discharge and spillage. Series 7138 hose lines are bonded to prevent separation and maximize flexibility, and the grayyellow color coding provides quick and easy identification. The hose features an EPDM tube that is resistant to compressor oil mist and an EPDM cover that is resistant to abrasion, heat and weathering.
