Raychem SCL Tubing 3:1

Raychem SCL is a Semi-Rigid 3:1 encapsulant-lined, heat-shrinkable tubing SCL is encapsulant-lined, heat-shrinkable tubing that provides moisture resistance, strain relief, and electrical insulation for electrical splices, terminations, breakouts, and mechanical connections. SCL is constructed as a dual-wall tubing. The outer wall is a semi-rigid, crosslinked polyolefin, while the inner wall is a meltable polyolefin that flows with the application of heat.
 
Heating SCL shrinks the outer jacket and melts the inner encapsulant wall to flow and fill surface irregularities. While hot, the tubing can be pinched and blocked to form a wire breakout. SCL provides a splash-resistant, moisture-resistant covering suitable for many applications. SCL also performs satisfactorily if briefly exposed to common solvents or chemicals. The installed tubing provides rugged protection against abrasion, vibration, and flexing. A wide range of applications can be accommodated with only a few sizes of SCL tubing.

The installed tubing provides rugged protection against abrasion, vibration, and flexing. A wide range of applications can be accommodated with only a few sizes of SCL tubing.

If any size of SCL is out of stock, Sumitomo W5DL can be used as an alternative. Both products share the same Mil-Spec, shrink ratio, and UL ratings.

 Looking for a great starter kit. Look no further than the SCL-KIT packed neatly in a durable plastic box loaded with all the commonly used sizes.

**Wall thickness will be less if tubing recovery is restricted during shrinkage.

We fold down 4ft sticks of tubing to keep shipping costs reasonable. However, during the hot weather months, there is a chance that the tubing will stick together in the folds.

If you would like the tubing shipping in a long box to avoid folding, please put a note on the order SHIP IN LONG BOX. We will add the additional shipping charges to the order.
