NT-MIL

Flexible, rugged, modified elastomeric

heat-shrinkable tubing

NT-MIL modified elastomeric heat-

shrinkable tubing offers outstanding

resistance to abrasion and physical

abuse while providing flexibility and

strain relief needed in many harness-

ing applications. NT-MIL tubing is

widely used for insulation, strain relief

and abrasion protection on cable

harnesses and wire bundles in the

military and aerospace industries. It

meets the stringent requirements of

AMS-DTL-23053/1, Classes 1 and 2.

Temperature rating

Full recovery temperature:

Continuous operating temperature:

135°C

–70°C to 121°C

NT-MIL tubing remains flexible at

temperatures as low as -70°C without

cracking. It also withstands heat

shock at 200°C without dripping,

flowing or cracking.

NT-MIL tubing is resistant to common

fluids and solvents including aviation

and ground vehicle fuels, lubricating

oil, and hydraulic fluids. It retains

excellent physical and electrical

properties following exposure.

No special skills are required to install

NT-MIL tubing. Using standard

heating tools, one operator can

complete an installation in minutes,

substantially reducing labor costs.

NT-MIL tubing is supplied in a wide

range of sizes. Because NT-MIL is

heat-shrinkable, each size can

accommodate a variety of harness

sizes, minimizing inventory and

related costs.
