RS PRO Heat Shrink Tubing Yellow 38.1 mm Sleeve Diameter x 1.2m Length, Polyolefin, 2:1 Shrink Ratio, Flame Retardant 399-653

RS PRO 399-653 Heat Shrink Tubing is designed for demanding electrical and industrial applications, offering robust protection for wire joints and connections. The sleeve has a diameter of 38.1 mm and a length of 1.2 meters, making it ideal for covering larger cables. Constructed from flexible polyolefin material, this tubing is both flame retardant and durable, with a shrink ratio of 2:1, meaning it shrinks to half its expanded diameter when heat is applied.

This heat shrink tubing is highly versatile, used to insulate and seal cable joints, terminal connections, and splices. It protects against environmental hazards like moisture, dust, and chemicals, and helps prevent mechanical abrasion. The tubing is suitable for bundling and organizing harnesses, providing strain relief and enhancing safety in installations.

The yellow colour ensures clear and easy identification of cables and wires in complex setups, making it valuable for colour coding in maintenance and construction environments. With a minimum shrink temperature of 90°C, the tubing offers an operating range from -55°C to +135°C, and withstands up to 200°C for short intervals, accommodating diverse electrical installation requirements.

Key benefits include fast shrinking, high flexibility, excellent electrical insulation, and resistance to commonly encountered fluids and solvents. The tubing is compliant with UL, MIL, and ASTM standards, making it suitable for military, aerospace, automotive, industrial machinery, electronics, and construction applications. Typical uses include electrical insulation of resistors and capacitors, mechanical and environmental protection, and repair of worn or damaged cable insulation.

Industrial contexts include electrical distribution, manufacturing, control panels, maintenance, and facility upgrades. The tubing is a practical choice for technicians and engineers seeking reliability and versatility in wire management.
