ATP Surethane NSF 51 polyurethane pressure tube suitable for compressed air and selected fluids and chemicals with higher working pressures while still retaining softness and flexibility. This product is a significant leap forward in tubing technology. The increased pressure rating has been achieved through advances in material technology. ATP Surethane NSF 51 polyurethane (PUR) Shore A 98 tubing is made from the highest quality raw materials available. It is ether-based to provide excellent hydrolysis, oil and cold resistance. ATP Surethane NSF 51 is strong and flexible and offers superior kink resistance compared to other tubing. It is 5 to 10 times more wear resistant and lighter in weight than any rubber hose. ATP Surethane NSF 51 tubing has an outside diameter made to extremely tight tolerances. It is ideal for use with push-to-connect fittings, as well as barb-type and compression fittings for simple installation. 180 psi working pressure at 70 degrees F. RoHS compliant. Applicable for pneumatic tools, pneumatic piping, vacuum, laboratories, robotics, motion control, instrumentation, agriculture, lube lines, painting systems, food and beverage.
