3M 7010305758 Heat Shrink Tubing 1/4 in 48 in White

Product Description

The 3M 7010305758 is a semi-rigid, heat shrinkable polyolefin tubing designed for demanding electrical and wire-termination applications. Manufactured using a co-extrusion process with selective cross-linking, it features a 2.5:1 shrink ratio and an integral meltable inner wall that flows when heated to create a sealed, moisture-resistant bond around the substrate. Each stick measures 48 inches in length with a 1/4-inch diameter and is supplied in white. Electricians, panel builders, and wire harness technicians use this tubing where a dual-wall construction provides both mechanical protection and environmental sealing in a single step.

This tubing is suited for residential and commercial electrical installations, industrial control panels, marine and automotive wiring, and anywhere a sealed, durable insulation sleeve is required over wire splices, terminals, or connector backshells. The semi-rigid wall construction maintains shape during installation, making it easier to handle on individual conductors or multi-conductor bundles. It is sold by the piece, with a minimum order quantity of 200 pieces per case.

Key Features

• 2.5:1 shrink ratio provides reliable, tight coverage over a range of substrate diameters
• Co-extruded dual-wall construction with a meltable inner adhesive layer for moisture sealing
• Semi-rigid polyolefin outer wall resists abrasion and mechanical stress after recovery
• 48-inch stick length allows field cutting to required lengths with minimal waste
• White color supports visual identification and cable organization in panel work

Compatibility

Designed as an OEM-style replacement or new-install heat shrink sleeve for use on wire splices, ring terminals, butt connectors, and similar electrical terminations requiring a sealed dual-wall tubing solution.

Installation Notes

Installation is performed by licensed electricians or qualified wire harness technicians working under applicable NEC guidelines. Power down and de-energize all circuits before applying heat shrink tubing to live wiring assemblies. Apply uniform heat using a calibrated heat gun, working from the center outward to prevent air pockets and ensure full adhesive flow from the inner wall. Do not use an open flame, as direct fire can cause uneven shrinkage and damage the tubing.
