3M 7100019689 Heat Shrink Tubing FP-301 1 in Blue

Product Description

The 3M 7100019689 is a thin-wall heat shrink tubing sold under the FP-301 product line, designed to provide reliable insulation, strain relief, and environmental protection across a broad range of electrical and industrial applications. FP-301 tubing delivers a balanced combination of electrical insulating properties, physical durability, and resistance to common chemicals. This spool supplies 100 feet of 1-inch diameter blue tubing, making it well suited for bundling wire harnesses, protecting splices, and color-coding conductors in panel wiring, control systems, and field service work.

FP-301 thin-wall heat shrink tubing is used in industrial wiring, military-specification applications, and commercial electrical installations where a clean, durable insulating sleeve is required. Electricians and instrumentation technicians commonly use this tubing during panel builds, wire management projects, and field repairs where consistent shrink performance and color identification are priorities. The blue color supports conductor identification and organization in multi-wire assemblies.

Key Features

• Thin-wall construction for low-profile insulation and strain relief on wire and cable terminations
• Balanced electrical, physical, and chemical resistance properties suitable for industrial and military applications
• Blue color for conductor identification and circuit organization
• Bulk 100-foot spool format reduces waste and supports high-volume field or shop use
• 1-inch diameter accommodates larger wire bundles and cable groups

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeving compatible with standard heat guns used in electrical, industrial, and military wiring applications where FP-301 series tubing is specified.

Installation Notes

Installation is typically performed by licensed electricians or qualified technicians using a calibrated heat gun. De-energize and lock out all circuits before applying heat shrink sleeving to any conductors or terminations. Apply heat evenly along the length of the tubing to achieve uniform shrinkage without scorching. Follow applicable NEC requirements and any governing military or industrial specifications for the installation environment.
