RS PRO Heat Shrink Tubing Blue 4.8 mm Sleeve Diameter x 1.2 m Length Polyolefin Flame Retardant 2:1 Ratio 397-900

RS PRO 397-900 Heat Shrink Tubing is a high-quality blue polyolefin tubing with a 4.8 mm sleeve diameter and 1.2 m length, engineered for industrial and electronic cable insulation and protection. Featuring a 2:1 shrink ratio, this tubing reliably shrinks to half its original diameter when heat is applied, ensuring a tight, durable seal on wire joints and cable connections.

Made from flexible and flame retardant polyolefin, this tubing performs within an operating temperature range of -55 to +135°C, with short-term tolerance up to 200°C. It meets rigorous industrial standards including ASTM, MIL, and UL certifications, complying with SAE-AMS-DTL-23053/5 Class 1 requirements for demanding environments.

This heat shrink tubing is ideal for providing electrical insulation and environmental protection against moisture, dust, and chemicals. It also delivers mechanical abrasion resistance and strain relief, enhancing the durability and reliability of wiring harnesses and cable assemblies.

The versatile tubing finds application across aerospace, military, automotive, industrial machinery, electronics, and construction equipment, used for insulating resistors, capacitors, wires, and cable splices. Its flame retardant properties and resistance to common fluids and solvents make it suitable for harsh industrial settings.

Additional advantages include easy cutting to size, radial shrinkage to secure durable seals, and color-coded identification facilitating wire and component organization. This tubing is a dependable solution for cable repair, protection, and organization in technical and industrial use cases.
