3M FP0.375BK100FT-S Heat Shrink Tubing 0.375 in 600V Black

Product Description

The 3M FP0.375BK100FT-S is a thin-wall, general-purpose heat shrink tubing from the FP-301 series, designed for electrical insulation, strain relief, and mechanical protection across a wide range of industrial and military wiring applications. Made from flexible polyolefin, this tubing features a 2:1 shrink ratio, a minimum expanded diameter of 0.375 inches, and a recovered diameter of 0.187 inches. It carries a 600-volt rating and maintains reliable performance across a temperature range of -55 to 135 degrees C. Licensed electricians and industrial maintenance technicians are the primary installers.

This tubing is suited for wire bundling, connector backshells, solder joint protection, and general-purpose insulation in both residential and commercial electrical work. Its flexible polyolefin construction resists moisture, mild chemicals, and abrasion, making it appropriate for panel wiring, automotive harnesses, and demanding industrial environments. The 100-foot spool format supports high-volume jobs where consistent, cut-to-length application is required. UL and CSA approvals make it acceptable for use in code-compliant electrical installations in the United States and Canada.

Key Features

• 2:1 shrink ratio with 0.375-inch expanded diameter and 0.187-inch recovered diameter
• 600-volt voltage rating suitable for low-voltage wiring and control circuits
• Flexible polyolefin material resists moisture, chemicals, and abrasion
• Shrinks at 212 degrees F with a continuous service range of -55 to 135 degrees C
• 2,400 psi tensile strength for durable mechanical protection
• UL and CSA approved; RoHS compliant
• 100-foot spool in black for easy cut-to-length field use

Compatibility

Designed as a general-purpose, OEM-style thin-wall heat shrink tubing suitable for standard electrical, industrial, and military wiring applications requiring a 0.375-inch expanded diameter and 600-volt insulation rating.

Installation Notes

Installation is typically performed by licensed electricians or qualified industrial maintenance technicians. De-energize all circuits and confirm lockout/tagout procedures are in place before applying heat shrink tubing to any conductor or connection. Use a calibrated heat gun rather than an open flame to ensure even shrinkage and avoid damaging the tubing or surrounding insulation. Follow applicable NEC requirements for insulation ratings and conductor protection in the specific application.
