3M FP0.750BK48IN-L Heat Shrink Tubing 0.75 in 48 in

Product Description

The 3M FP0.750BK48IN-L is a thin-wall, flexible polyolefin heat shrink tubing from the FP-301 series, rated for 600 volts and designed for wire insulation, bundling, strain relief, and environmental sealing in industrial and electrical applications. It features a 2:1 shrink ratio with a minimum expanded diameter of 0.75 inches and a maximum recovered diameter of 0.375 inches, at a length of 48 inches per piece. The tubing shrinks at 212 degrees F and carries a continuous service temperature range of -55 to 135 degrees C. It is installed by electricians, maintenance technicians, and military/industrial assembly personnel who require reliable, UL- and CSA-listed tubing with consistent wall thickness and chemical resistance.

This tubing is suited for residential, commercial, and industrial electrical installations where a low-profile, flexible sleeve is needed over wire terminations, splices, connector barrels, and bus bars. The FP-301 series is commonly used in panel wiring, control cabinets, harness assembly, and field repair work. Each piece ships at 48 inches, allowing field trimming to length. The black color aids heat absorption during shrink and provides UV resistance in exposed installations. Cases contain 50 pieces for shop stocking or job-lot use.

Key Features

• 2:1 shrink ratio — expands to 0.75 inches, recovers to 0.375 inches maximum
• 600-volt rating suitable for standard low- and medium-voltage wiring applications
• Thin-wall flexible polyolefin construction with 0.03-inch wall thickness
• Activation temperature of 212 degrees F using a heat gun or oven
• Tensile strength of 2400 psi for durable mechanical protection
• UL and CSA listed; RoHS compliant for use in regulated and export applications

Compatibility

Designed as an OEM-style thin-wall heat shrink sleeve compatible with standard wire gauges and connector barrels that fall within the 0.75-inch maximum expanded diameter range. No specific wire gauge or connector model compatibility was provided in the product data.

Installation Notes

Installation is performed by electricians or assembly technicians using a calibrated heat gun, heat oven, or infrared source; open flame is not recommended as it risks uneven shrink and material damage. Power down and de-energize all circuits before sleeving wire terminations or splices. Slide tubing over the conductor before making the final connection, then apply heat evenly along the length from one end to the other to prevent air pockets. Follow NEC and applicable local electrical codes for insulation and strain-relief requirements.
