3M 7100020273 FP-301 3/8 Inch Clear Heat Shrink Tubing

Product Description

The 3M 7100020273 is a thin-wall heat shrink tubing sold under the FP-301 product line, supplied on a 200-foot bulk spool. FP-301 is a polyolefin-based tubing rated for electrical insulation, mechanical protection, and moisture resistance across a wide range of industrial and military-grade applications. The 3/8-inch nominal diameter sizing fits standard wire bundles, terminals, and splice connections encountered in electrical, HVAC control wiring, and equipment harness work. The clear jacket allows visual inspection of the underlying conductor or connection after shrink without removing the tubing.

FP-301 thin-wall heat shrink tubing is used in residential and commercial electrical installations, OEM equipment manufacturing, panel wiring, and field service repairs. The 200-foot spool format suits high-volume shops and contractors who cut to length on the bench rather than working from short pre-cut pieces. The clear color is commonly specified where identification markings on the wire must remain readable through the tubing after installation.

Key Features

• Thin-wall construction for low-profile insulation over conductors and terminals
• Clear jacket allows visual inspection of connections without removal
• 200-foot bulk spool reduces per-foot cost for high-volume applications
• Polyolefin material provides electrical insulation and resistance to moisture and common chemicals
• 3/8-inch nominal diameter suits a wide range of wire gauges and terminal sizes

Compatibility

Designed as a general-purpose thin-wall heat shrink tubing for industrial and military electrical applications where 3/8-inch nominal diameter polyolefin sleeving is specified.

Installation Notes

Heat shrink tubing is installed by licensed electricians and qualified technicians using a heat gun or similar controlled heat source. De-energize all circuits completely before applying tubing over any conductor or terminal. Apply heat evenly along the length of the tubing to achieve uniform shrink and avoid scorching. Do not use an open flame as the heat source, as uneven heat can damage the tubing or the underlying insulation.
