The RS 399-912 Clear Heat Shrink Tubing is a premium-quality 2:1 heat shrink sleeve designed to provide reliable insulation, mechanical protection, and strain relief for electrical wires, cable joints, and terminals. Manufactured in Japan from high-quality transparent polyolefin, this flexible heat shrink tubing allows wire identification labels, marker tags, and cable markings to remain visible after shrinking, making it ideal for professional electrical installations.

With a 3.2 mm inside diameter and 1.2 m length, the tubing shrinks uniformly to half its original diameter when heated, creating a secure protective covering around wires and connectors. It provides excellent resistance to abrasion, moisture, chemicals, UV exposure, and environmental wear, making it suitable for marine, automotive, industrial, telecommunications, aerospace, and general electrical applications.

Approved to SAE-AMS-DTL-23053, this high-performance heat shrink tubing delivers dependable insulation and long-lasting protection in demanding environments.
