3M 7000133692 Heat Shrink Sleeve 6 in Polyolefin 2:1

Product Description

The 3M 7000133692 is a polyolefin heat shrink sleeve designed to protect wire splices, terminals, and electrical connections from moisture, corrosion, and mechanical damage. With a 2:1 shrink ratio and a post-shrink inside diameter of 0.093 inches, this sleeve delivers a tight, conforming fit over conductors and connectors. The material activates at 212 degrees F and operates reliably across a wide temperature range of -67 to 275 degrees F. Electricians and wire harness technicians use it where a durable, flame-retardant sleeve is required on small-gauge conductors and component leads.

This sleeve is suited for electrical and electronics applications in residential, commercial, and industrial settings. At 6 inches in overall length, it provides sufficient coverage for standard terminal and splice protection tasks. The black polyolefin construction resists corrosion, solvents, fungus, and splitting, making it a practical choice for both indoor panel work and exposed wiring environments. Each package contains 10 pieces, allowing multiple connections to be serviced from a single order.

Key Features

• 2:1 shrink ratio with 0.093 inch post-shrink inside diameter for a snug fit on small conductors
• Activates at 212 degrees F using a heat gun or similar heat source
• Wide operating range: -67 degrees F to 275 degrees F
• Wall thickness of 0.020 inches after shrinking for added insulation and protection
• Resistant to corrosion, solvents, fungus, splitting, and flame spread
• Meets multiple standards including UL Recognized (File E39100), CSA Certified, AMS3636, AMS3637, and DTL-23053/5 Class 1 and Class 2

Compatibility

Designed as an OEM-style heat shrink sleeve for use on small-gauge wire terminations, splices, and electrical components requiring polyolefin tubing with a 2:1 shrink ratio.

Installation Notes

Installation is performed by licensed electricians or qualified technicians following applicable NEC guidelines. De-energize all circuits before applying the sleeve over conductors or terminals. Use a calibrated heat gun to apply even heat around the sleeve until full shrinkage is achieved; avoid open flame tools that can scorch the material. Verify post-shrink fit before restoring power to the circuit.
