PSTH Tubing Elastomeric Polyester, Flexible Data Sheet Product Description TM 3M PSTH tubing is a high performance, rugged heat shrinkable tubing designed for harsh operating conditions. The tubing is made from flexible elastomeric polyester and has a continuous operating temperature range of -55C (-70F) to 150C (302f). PSTH is resistant to a wide range of solvents and chemicals including aviation fuel, diesel fuel, lubricating oils and hydraulic fluid. 3M PSTH tubing is specifically designed to pass the SC-X15111C military specification but also meets the functional requirements of MIL-DTL23053/16. Typical Applications Standard Color 3M PSTH tubing is primarily designed for wire harnessing applications on military ground vehicles. It was primarily developed for the M-1 tank program, but is well suited for any application where conditions call for a high performance heat shrink tubing, particularly where the tubing will be exposed to petroleum based fluids. PSTH is also an excellent choice for heavy duty equipment and offroad vehicles. Black. Shrink Ratio 3M PSTH tubing has a 2:1 shrink ratio. When 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. Standard Packaging Spools. Ordering Information Order PSTH Tubing by product name, size equivalent to the expanded inside diameter, package type and color. Always order the largest size that will shink snugly over the component to be covered. Example: PSTH, 3/8", black, spools.
