3M 7000133687 Heat Shrink Sleeve 0.5 in Polyolefin 2:1

Product Description

The 3M 7000133687 is a dual-wall polyolefin heat shrink sleeve designed for electrical insulation, bundling, and environmental protection of wires, connectors, and terminations. It ships at 0.5 inches inner diameter and shrinks to 0.25 inches ID at a 2:1 ratio when exposed to a minimum shrink temperature of 212 degrees F. At 6 inches in overall length, it is suited for individual wire splices, terminal insulation, and mechanical strain relief. Electricians and low-voltage technicians use this sleeve in panel wiring, field splices, and raceway terminations where a clean, durable finish is required.

This sleeve is applicable to residential and light commercial electrical work, including control wiring, panel terminations, and field-fabricated harnesses. Its operating temperature range of -67 degrees F to 275 degrees F makes it viable in both indoor mechanical rooms and outdoor enclosures. The black color aids UV identification and is common in equipment and industrial wiring applications. Each package contains 10 sleeves and a minimum order quantity of one package applies.

Key Features

• 2:1 shrink ratio reduces from 0.5 inches ID to 0.25 inches ID for a firm, form-fitting finish
• Polyolefin construction provides corrosion, fungus, solvent, and split resistance
• Fire-resistant material supports use in code-sensitive electrical installations
• Wide operating temperature range of -67 degrees F to 275 degrees F
• Wall thickness of 0.025 inches after shrinking for consistent mechanical protection
• Meets AMS3636, AMS3637, DTL-23053/5 Class 1 and Class 2, UL Recognized File E39100, CSA Certified, and ABS Type Approved standards

Compatibility

Designed as an OEM-style and general-use heat shrink sleeve suitable for wire and connector insulation in residential and commercial electrical installations where a 2:1 polyolefin sleeve in the 0.5 inch ID range is specified.

Installation Notes

Installation is performed by licensed electricians or qualified low-voltage technicians. Power down the circuit and verify zero voltage before applying the sleeve over any conductor or termination. Apply heat evenly using a heat gun set to an appropriate temperature, working from the center outward to prevent air pockets. Follow applicable NEC requirements for wire insulation and splicing methods in the jurisdiction where the work is performed.
