3M 7100022418 Heat Shrink Thin-wall Tubing 1/4 in Black

Product Description

The 3M 7100022418 is a thin-wall heat shrink tubing supplied on a 100-foot spool, sized at 1/4 inch diameter and finished in black. Manufactured from flexible polyolefin, this tubing shrinks down over conductors, splices, terminals, and wire bundles when heat is applied, providing insulation, strain relief, and environmental protection. It is lightweight and designed for use in electrical, HVAC control wiring, and general-purpose wiring applications where a clean, durable sleeve is needed without the added wall thickness of dual-wall or adhesive-lined products.

This tubing is suited for residential and commercial electrical and HVAC wiring tasks where low-voltage or line-voltage conductors require insulation or bundling after splicing or termination. Electricians, HVAC technicians, and control wiring specialists commonly use FP-301 series thin-wall tubing when working on control panels, wire harnesses, and field-installed connections. The 100-foot spool length supports multiple installations from a single package, reducing material handling on larger jobs.

Key Features

• Flexible polyolefin construction provides consistent shrink performance and electrical insulation
• 1/4 inch nominal diameter fits a wide range of conductor and terminal sizes
• Thin-wall profile keeps finished bundle diameter compact after shrinking
• Black color aids in UV resistance and blends with standard wire management practices
• 100-foot spool length supports high-volume or multi-connection installations

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve compatible with standard wire, terminal, and splice insulation applications requiring a 1/4 inch nominal shrink tubing diameter.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians following applicable NEC guidelines. Slide the tubing over the conductor or splice before making the final connection, then apply uniform heat using a heat gun, working along the tubing length to achieve an even shrink. Avoid using an open flame, which can scorch the tubing or damage adjacent components. Ensure the work area is de-energized and locked out before applying tubing to any live circuit.
