RS PRO Heat Shrink Tubing Polyolefin Black 12.7 mm Sleeve Diameter, 1.2 m Length, 2:1 Shrink Ratio 398-161

RS PRO 398-161 Heat Shrink Tubing is engineered to deliver high-quality cable protection and insulation in demanding industrial environments. Boasting a flexible Polyolefin composition, this tubing is black and features a 12.7 mm sleeve diameter in its expanded state, shrinking to just 6.4 mm when heated. With a total length of 1.2 meters per tube and an efficient 2:1 shrink ratio, it is ideal for covering, repairing, and protecting wire joints, terminals, components, and splices.

Built to meet robust standards including RoHS, UL 224 VW-1, IEC 60684-3-212, CSA C22.2 No. 198.1, and MIL SAE-AMS-DTL 23053/5 Class 1, the RS PRO tubing guarantees reliable safety and performance. It is flame retardant, offering additional protection against fire hazards in electrical and electronic installations. Although not halogen-free, its Polyolefin construction provides resilience to abrasions, fluids, solvents, and harsh chemicals commonly encountered in industrial settings.

Installation is straightforward: simply cut the desired length, slide the tubing over the joint or component, and heat to a minimum of 90°C. The tubing will radially shrink to half its diameter, tightly sealing and insulating the joint, providing strain relief and mechanical protection. The wide operating temperature range of -55°C to +135°C - with temporary exposure up to 200°C - makes it suitable for demanding applications such as automotive wiring, military installations, aerospace harnessing, and electronics manufacturing.

Applications include: electrical insulation for resistors, capacitors, and wiring; protection against environmental ingress (moisture, dust, chemicals); bundling and organizing harnesses and cables; strain relief at connector joints; and repairs of worn cable insulation. Color-coded black tubing assists in easy identification and neat cable management.

RS PRO Heat Shrink Tubing is frequently deployed across sectors such as industrial machinery, laboratory systems, HVAC, manufacturing plants, water treatment setups, automotive maintenance, and commercial electronics assemblies. Its proven durability and compliance with international standards ensure peace of mind for engineers and technicians.
