3M FP0.750BK48IN-S Heat Shrink Tubing 0.75 in 48 in Black

Product Description

The 3M FP0.750BK48IN-S is a thin-wall, flexible polyolefin heat shrink tubing from the FP-301 series, rated for 600 volts and designed for electrical insulation, bundling, and environmental protection of wire and cable assemblies. It features a 2:1 shrink ratio, transitioning from a minimum expanded diameter of 0.75 inches down to a maximum recovered diameter of 0.375 inches. The tubing activates at 212 degrees F and carries a continuous service temperature range of -55 to 135 degrees C. Wall thickness measures 0.03 inches in the recovered state. Electricians, maintenance technicians, and MRO professionals working in industrial and military-grade wiring applications install this tubing as a standard step in harness fabrication and repair work.

This tubing is well suited for residential and commercial electrical work, control panel wiring, wire splices, terminal insulation, and cable bundling where UL and CSA compliance is required. The FP-301 series is recognized for balancing electrical, physical, and chemical performance across a broad range of industrial and military applications. Its black color and 48-inch length make it practical for bench-cut or as-needed field use. Each case contains 12 pieces. The flexible polyolefin material maintains integrity across temperature extremes and resists common shop chemicals and fluids encountered during installation.

Key Features

• 2:1 shrink ratio — 0.75 inch expanded diameter recovers to 0.375 inch maximum
• Rated 600 volts for use in standard low-voltage wiring and harness applications
• Activates at 212 degrees F with an operating range of -55 to 135 degrees C
• Thin-wall flexible polyolefin construction — 0.03 inch recovered wall thickness
• Tensile strength of 2,400 psi for durable mechanical and electrical protection
• UL and CSA approved; RoHS compliant
• Black, 48-inch length — 12 pieces per case

Compatibility

Designed as an OEM-style replacement and standard-stock heat shrink tubing for use on wire, cable, and terminal assemblies requiring a 0.75 inch expanded diameter thin-wall sleeve with 600-volt insulation rating in industrial or commercial electrical applications.

Installation Notes

Installation is performed by licensed electricians or qualified wiring technicians. De-energize all circuits before applying heat shrink to live conductors or splice points. Apply heat evenly using a heat gun along the length of the tubing, working from the center outward to avoid trapping air bubbles. Follow NEC guidelines for insulation requirements and conductor sizing when using heat shrink as primary or secondary insulation in panel or harness work.
