NT-MIL Flexible, rugged, modified elastomeric heat-shrinkable tubing NT-MIL modified elastomeric heat- NT-MIL tubing remains flexible at No special skills are required to install shrinkable tubing offers outstanding temperatures as low as -70C without NT-MIL tubing. Using standard resistance to abrasion and physical cracking. It also withstands heat heating tools, one operator can abuse while providing flexibility and shock at 200C without dripping, complete an installation in minutes, strain relief needed in many harness- flowing or cracking. substantially reducing labor costs. ing applications. NT-MIL tubing is widely used for insulation, strain relief NT-MIL tubing is resistant to common NT-MIL tubing is supplied in a wide and abrasion protection on cable fluids and solvents including aviation range of sizes. Because NT-MIL is harnesses and wire bundles in the and ground vehicle fuels, lubricating heat-shrinkable, each size can military and aerospace industries. It oil, and hydraulic fluids. It retains accommodate a variety of harness meets the stringent requirements of excellent physical and electrical sizes, minimizing inventory and AMS-DTL-23053/1, Classes 1 and 2. properties following exposure. related costs.
