3M 7000133578 Heat Shrink Polyolefin Tubing 1.5x48 in

Product Description

The 3M 7000133578 is a flexible polyolefin heat shrink tubing designed to protect electronic components, insulate wire splices, and bundle wiring in demanding electrical and mechanical applications. Sold as a single 48-inch length with a 1.5-inch diameter, this tubing shrinks uniformly when heat is applied, conforming tightly to the underlying components. The EPS200 series construction uses a dual-wall polyolefin material that delivers reliable electrical insulation and mechanical abrasion resistance. Licensed electricians, HVAC technicians, and electronic assembly professionals commonly specify this tubing for field service and panel work.

This tubing is appropriate for residential and light commercial applications where wire splices, terminal connections, and component leads require environmental and mechanical protection. It is suited for use in electrical enclosures, control panels, low-voltage wiring harnesses, and HVAC equipment wiring. The 48-inch stick length accommodates longer runs or can be cut to shorter segments as the job requires. It is sold individually, with a minimum order quantity of 5 units.

Key Features

• Flexible polyolefin construction provides consistent shrink performance and durable insulation
• 48-inch length allows full-length coverage or field-cut segments
• 1.5-inch diameter fits a wide range of wire bundles and component bodies
• Protects wire splices, electronic components, and bundled conductors from abrasion and moisture
• Lightweight at 0.37 pounds per unit, reducing harness weight in finished assemblies

Compatibility

Designed as an OEM-style replacement and general-use heat shrink tubing suitable for electrical wiring, wire splice protection, and component insulation across residential and commercial electrical and HVAC applications.

Installation Notes

Installation is typically performed by licensed electricians or qualified HVAC technicians in accordance with NEC requirements for insulation and splice protection. Power down all circuits and verify zero voltage before applying tubing to live splices or terminations. Apply heat evenly using a heat gun, working from the center of the tubing outward to prevent trapped air bubbles or uneven shrinkage. Do not use an open flame as a heat source, as uncontrolled heat can damage the tubing or underlying conductors.
