3M 7000133688 Heat Shrink Tubing 1/4 in 6 in Black 10 Pack

Product Description

The 3M 7000133688 is a thin-wall heat shrink tubing sold in a 10-piece pack, based on the FP301 series. Each piece measures 6 inches in length with a 1/4 inch nominal diameter before shrinking. This tubing is designed to provide electrical insulation, moisture resistance, and mechanical protection for wire splices, terminals, and harness breakouts. It is black in color and suitable for use in electrical, HVAC control wiring, and general wiring applications where a clean, reliable insulating sleeve is needed. Electricians, HVAC technicians, and control wiring specialists regularly use this product during installation and service work.

This tubing is appropriate for residential and light commercial electrical and low-voltage control wiring applications. It fits over wire terminations, connector bodies, and exposed conductor ends where a snug insulating layer is required after heat application. The FP301 thin-wall construction keeps overall bundle diameter low, making it well suited for tight wire routing in panels, junction boxes, and equipment harnesses.

Key Features

• Thin-wall construction minimizes added bulk over terminated connections
• 1/4 inch nominal diameter accommodates a range of wire gauges and small terminals
• 6 inch piece length provides manageable, cut-to-use segments
• Black color supports polarity or circuit identification by color convention
• Pack of 10 pieces allows efficient stocking for recurring service calls
• FP301 series construction offers reliable insulation and moisture resistance after shrinking

Compatibility

Designed as a general-purpose thin-wall heat shrink sleeve compatible with standard wire and cable termination applications requiring a 1/4 inch nominal diameter insulating sleeve.

Installation Notes

Installation is performed by electricians and HVAC technicians following applicable NEC guidelines for insulation and wire protection. De-energize all circuits before applying heat shrink tubing to any termination or splice. Use a heat gun set to an appropriate low heat shrink temperature and apply heat evenly around the tubing to achieve a uniform, wrinkle-free seal. Do not use an open flame to shrink the tubing, as uneven heat can damage the material or the underlying conductor insulation.
