SCL Semirigid, encapsulant-lined, heat-shrinkable tubing SCL is encapsulant-lined, heat- Heating SCL shrinks the outer jacket The installed tubing provides rugged shrinkable tubing that provides and melts the inner encapsulant protection against abrasion, vibration, moisture resistance, strain relief, wall to flow and fill surface and flexing. A wide range of and electrical insulation for electrical irregularities. While still hot, the applications can be accommodated splices, terminations, breakouts, tubing can be pinched and blocked with only a few sizes of SCL tubing. and mechanical connections. to form a wire breakout. SCL provides a splash-resistant, SCL tubing is UL-recognized at SCL is constructed as a dual-wall moisture-resistant covering suitable 125C, 600 V, and meets the tubing. The outer wall is a semirigid, for many applications. SCL also requirements of AMS-DTL-23053/4, crosslinked polyolefin, while the inner performs satisfactorily if briefly Class 1. wall is a meltable polyolefin that flows exposed to common solvents with the application of heat. or chemicals.
