Heat-Shrink Tubing EPM model E-651-0155, 1.50/0.75 mm, blue

EPM heat-shrink tubing model E-651-0155 in blue provides a protective sleeve for small wires and cable assemblies with nominal dimensions of 1.50/0.75 mm. The tubing is designed to contract uniformly when exposed to heat, forming a tight insulating barrier around joints, terminals and exposed conductors. It is suitable for electrical insulation, strain relief and basic mechanical protection in both industrial and domestic environments.

Advantages

The tubing offers reliable electrical insulation and mechanical support after shrinking, reducing the risk of short circuits and improving durability of connections. Its small cross-section is tailored for fine wiring and compact assemblies, while the blue color allows simple visual identification. The material is flexible before and after shrinking, making it easy to route in confined spaces and compatible with soldered or crimped terminations.

Suitable for

• Insulating soldered or crimped wire joints in electronics repair
• Protecting individual conductors in wiring harnesses and cable looms
• Prototyping and small-scale DIY electrical projects
• Marking and color-coding small cables and connectors

Key specifications

• Nominal diameter before/after shrink: 1.50 mm / 0.75 mm
• Color: blue
• Intended function: electrical insulation, strain relief and mechanical protection
• Suitable wire size: small-gauge conductors and compact assemblies
• Material properties: flexible polymer designed to shrink when heated

How to use

Select a length of tubing that covers the joint with some overlap on both sides, slide it over the conductor before making the connection, and then make the solder or crimp termination. Apply heat evenly along the tubing using a heat gun, hot-air station, or controlled flame at a safe distance until the tubing contracts and forms a snug fit around the joint. Allow the assembly to cool before handling to ensure the sleeve sets and provides full insulation and mechanical support.

Usage recommendations

For best results, use a regulated heat gun or hot-air tool to avoid overheating adjacent components. Verify compatibility with the operating temperatures and chemicals present in your application and ensure the tubing covers exposed conductors fully. When color-coding, choose consistent color schemes to simplify later identification and maintenance.
