3M 7100020161 FP-301 Heat Shrink Tubing 1/8 in Clear 500 Ft

Product Description

The 3M 7100020161 is a thin-wall polyolefin heat shrink tubing supplied on a 500-foot bulk spool. Sold under the FP-301 product line, it features a 2:1 shrink ratio and is designed to provide electrical insulation, strain relief, and environmental protection for wire, cable, and component terminations. The 1/8-inch expanded diameter suits small-gauge conductors and connector bodies. Electricians, panel builders, and MRO technicians working in industrial or military-specification environments select this tubing for its consistent wall thickness and clean shrink performance.

FP-301 thin-wall heat shrink tubing is used across a broad range of applications including wire harnessing, splices, solder joint protection, and bundling in industrial control panels, aerospace assemblies, and field service work. The clear color allows visual inspection of the underlying conductor or label after shrinking. The 500-foot spool format is suited for shops and service operations that consume tubing in volume and require a consistent, ready supply at the workbench.

Key Features

• 1/8-inch expanded inner diameter accommodates small-gauge conductors and component leads
• Thin-wall construction allows fast, even heat shrink with a standard heat gun
• Clear tubing permits visual inspection of connections and printed labels after installation
• 500-foot bulk spool minimizes changeover time in high-volume wiring operations
• Suitable for industrial and military-specification wiring applications

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve for use on small-gauge wire, cable terminations, and component leads in industrial and military wiring assemblies.

Installation Notes

Installation is performed by licensed electricians or trained wire harness technicians. De-energize all circuits and verify zero voltage before applying heat shrink over any live termination point. Use a calibrated heat gun rather than an open flame to ensure uniform shrinkage and avoid damage to the tubing or adjacent insulation. Follow applicable NEC or customer-specified wiring standards for minimum insulation requirements at each termination.
