3M 7100044548 Nst Heat Shrink Tubing 3/16 in Black 200 Ft

Product Description

The 3M 7100044548 is a modified polychloroprene (NST) heat shrink tubing designed for applications that demand a tough, highly flexible protective covering. Sold in a 200-foot spool, it is rated for continuous operation from -94 degrees F to 250 degrees F, making it suitable for extreme-temperature environments. When heated above 275 degrees F, the tubing rapidly shrinks to a skintight fit over the substrate. Licensed electricians, maintenance technicians, and industrial tradespeople use this tubing for wire bundling, insulation, and mechanical protection in demanding service conditions.

This tubing is well suited for electrical, industrial, and mechanical applications where exposure to oils, common fluids, and solvents is expected. The flexible nature of the material holds up in cold environments without becoming brittle, making it a reliable choice for both indoor and outdoor installations. It is available in black and measures 3/16 inch in diameter. The material accepts hot-stamp and print-wheel marking, which supports labeling and identification needs on wiring harnesses and cable assemblies.

Key Features

• Continuous operating range from -94 degrees F to 250 degrees F for extreme-environment use
• Shrinks to a skintight fit when heated above 275 degrees F
• Superior cut-through and abrasion resistance extends service life in high-wear applications
• Excellent resistance to oils, common fluids, and solvents
• Maintains flexibility at low temperatures — no cracking or stiffening in cold service
• Compatible with hot-stamp and print-wheel marking methods for cable identification

Compatibility

Designed as an OEM-style protective sleeving solution for electrical wiring, cable harnesses, and mechanical components requiring flexible, heat-shrinkable insulation and abrasion protection.

Installation Notes

Installation is typically performed by licensed electricians or qualified maintenance technicians. De-energize all circuits before applying heat shrink tubing to any wiring or components. Use a calibrated heat gun to apply even heat around the tubing circumference — avoid open flame sources, which can cause uneven shrink or material damage. Follow applicable NEC guidelines for insulation ratings and conductor protection requirements in the target installation environment.
