3M 36716 Flexible Polyolefin Heat Shrink Tubing 3/4 in

Product Description

The 3M 36716 is a flexible polyolefin heat shrink tubing supplied in 4-foot sticks and packaged 12 sticks per box. Designed for wire bundling, insulation, and strain relief applications, this tubing shrinks when heat is applied to form a tight, protective sleeve over conductors, terminals, and splices. The 3/4-inch diameter and black color make it well suited for electrical and low-voltage wiring harness work where a clean, finished appearance is required. Licensed electricians, HVAC technicians, and industrial maintenance crews reach for this type of tubing when protecting connections in conduit, control panels, or equipment wiring.

This tubing is appropriate for residential and light commercial electrical work, HVAC control wiring, pool and spa equipment wiring, and general-purpose wire management tasks. The flexible polyolefin material performs across a broad range of service environments, including applications where routing around bends or in tight enclosures is necessary. It installs without adhesives and requires only a heat gun or similar heat source to activate the shrink process.

Key Features

• Flexible polyolefin construction resists cracking and remains pliable after shrinking
• 3/4-inch nominal diameter accommodates common wire bundles and terminal sizes
• 4-foot stick length allows easy cutting to job-specific lengths
• Black color provides UV resistance and a clean finished look in exposed wiring runs
• 12 sticks per box for convenient stocking on service vehicles and in supply rooms

Compatibility

Designed as a general-purpose flexible polyolefin heat shrink tubing suitable for standard electrical insulation, bundling, and strain relief applications across trade disciplines.

Installation Notes

Installation is performed by licensed electricians or qualified technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink tubing to any wiring or terminal. Use a calibrated heat gun rather than an open flame to ensure even, controlled shrinkage without damaging the tubing or adjacent components. Cut sticks to the required length before positioning over the conductor or splice, as the tubing cannot be repositioned once heat is applied.
