3M FP0.188BK250FT-L FP-301 Heat Shrink Tubing 250 Ft

Product Description

The 3M FP0.188BK250FT-L is a thin-wall, flexible polyolefin heat shrink tubing supplied on a 250-foot spool. It carries a 2:1 shrink ratio, meaning a minimum expanded diameter of 0.187 inches recovers to a maximum of 0.093 inches when heat is applied at 212 degrees F. The tubing is rated for 600 volts and operates across a temperature range of -55 to 135 degrees C, making it suitable for demanding electrical insulation, bundling, and environmental sealing tasks in both industrial and military-grade wiring work. Wall thickness is 0.02 inches. Electricians, MRO technicians, and panel builders reach for this tubing when they need a dependable, UL- and CSA-listed thin-wall solution with consistent recovery characteristics.

This tubing is well suited for insulating wire splices, terminations, and connector backshells in control panels, industrial equipment, and harness assemblies. The flexible polyolefin construction resists moisture, mild chemicals, and abrasion without adding significant bulk to finished wire runs. The 250-foot spool length makes it practical for production and service environments where multiple sizes and lengths are cut to order. It performs reliably in both residential electrical work and heavier commercial or industrial applications where UL and CSA listing is required by specification.

Key Features

• 2:1 shrink ratio with 0.187 inch expanded diameter recovering to 0.093 inches
• 600-volt rating meets common insulation requirements for low-voltage wiring
• Operating range of -55 to 135 degrees C suits harsh or wide-temperature environments
• Flexible polyolefin material provides moisture resistance and chemical resistance
• Tensile strength of 2400 psi for durable, long-lasting insulation coverage
• UL and CSA listed; RoHS compliant for regulated applications
• 250-foot spool format reduces waste and speeds high-volume termination work

Compatibility

Designed as a general-purpose thin-wall heat shrink tubing for electrical insulation and wire bundling applications across industrial, commercial, and military wiring assemblies. Suitable for use wherever a UL- and CSA-listed flexible polyolefin 2:1 shrink tubing at the 3/16-inch nominal size is specified.

Installation Notes

Installation is typically performed by licensed electricians or trained wire harness technicians. Power down and de-energize all circuits before applying heat shrink over live conductors or terminations. Use a heat gun calibrated for the required shrink temperature; open flame sources risk uneven recovery and material damage. Follow applicable NEC requirements for insulation rating and conductor sizing when selecting tubing for a specific application.
