NST Tubing Modified Chlorinated Polyolefin (Neoprene ) Data Sheet Product Description Typical Applications Standard Color 3 M N S T Tubing provides superior cut- N S T Tubing is recommended for B l a c k . through and abrasion resistance and is applications requiring a tough, highly Standard Packaging u n a ffected by common fluids and flexible covering. It is particularly useful solvents. Resistance to oils is excellent. for fabrication and repair of flexible S p o o l s . The tubing maintains flexibility at low harnesses and wire bundles and for temperatures and can be readily marked covering hydraulic couplings.

When ordering NST Tu b i n g , please indicate the applicable Shrink Ratio specification required. N S T Tubing has a 2:1 shrink ratio. W h e n Example: NST, 3/16 , spools, black. freely recovered, the tubing will shrink to 50% of its as-supplied internal diameter. The recovered wall thickness is proportional to the degree of recovery.
