3M 7100083140 FP301 Heat Shrink Tubing 3/8 in 48 in White

Product Description

The 3M 7100083140 is a thin-wall heat shrink tubing from the FP-301 series, designed to provide reliable insulation and mechanical protection for electrical wiring and connections. Constructed for a wide range of industrial and military applications, this tubing delivers a balanced combination of electrical insulation, physical durability, and chemical resistance. At 3/8 inch diameter and 48 inches in length, it is well suited for medium-gauge wire bundles and terminal insulation tasks encountered in HVAC, electrical, and other trade service work. Each piece weighs approximately 0.05 pounds, keeping it lightweight and easy to handle on the job.

This heat shrink tubing is used wherever wiring connections require durable insulation and environmental protection. Common applications include wire splicing, terminal insulation, bundling, and strain relief in both residential and commercial electrical installations. The FP-301 series is a standard choice among electricians and HVAC technicians who need consistent, repeatable results when protecting low-voltage and line-voltage connections in panel work, equipment wiring, and field repairs.

Key Features

• Thin-wall construction for a low-profile fit over standard wire gauges and terminals
• Balanced electrical, physical, and chemical properties suited for industrial and military-grade applications
• 48-inch length provides flexibility for cutting to required segment sizes on the job
• White color allows for easy visual identification and labeling of wire runs
• Lightweight at 0.05 pounds per piece, minimizing added bulk in tight enclosures

Compatibility

Designed as a standard thin-wall heat shrink sleeve for general electrical insulation and wire protection tasks across industrial and commercial wiring applications.

Installation Notes

Installation is typically performed by licensed electricians or HVAC technicians. De-energize all circuits before applying heat shrink tubing to any wiring or connections. A heat gun set to the appropriate shrink temperature should be used; open flame sources are not recommended as they can cause uneven shrinkage or damage to the tubing. Follow applicable NEC guidelines for wire insulation and termination practices in the jurisdiction where the work is performed.
