3M 7000133581 Heat Shrink Tubing EPS300 1/4 in 48 in

Product Description

The 3M 7000133581 is a thin-wall heat shrink tubing from the EPS-300 series, designed for environmental protection and electrical insulation in demanding trade applications. Supplied in 48-inch sticks, this tubing shrinks down to form a tight seal over wire splices, terminals, and cable ends, protecting connections from moisture, abrasion, and contaminants. It suits the installation requirements of licensed electricians and low-voltage technicians who need a reliable, field-cut insulation sleeve. The EPS-300 construction delivers consistent performance in residential, commercial, and light industrial wiring applications.

This tubing is used wherever wire and cable connections require durable environmental protection. Typical applications include protecting spliced conductors, insulating terminal ends, and sealing cable entries in HVAC control wiring, electrical panels, and equipment hookups. Each stick measures 48 inches, allowing the installer to cut to length as needed on the job. The minimum order quantity is 12 pieces per case, making it practical for stocking service vans and shop inventory.

Key Features

• Thin-wall heat shrink construction provides a low-profile insulating sleeve after recovery
• 48-inch stick length allows field cutting to any required size
• 1/4-inch nominal diameter suits small-gauge wire terminations and splices
• EPS-300 series formulation offers environmental protection against moisture and abrasion
• Lightweight at 0.07 pounds per stick, minimizing added bulk at connection points

Compatibility

Designed as an OEM-style replacement and general-purpose heat shrink sleeve suitable for use in residential, commercial, and light industrial electrical and low-voltage wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified low-voltage technicians following applicable NEC guidelines. De-energize all circuits before applying heat shrink tubing to any live wiring assembly. Use a heat gun set to the appropriate recovery temperature and apply heat evenly along the length of the tubing to achieve full shrinkage without scorching. Do not use an open flame, as uneven heat can damage the tubing or underlying conductors.
