2.5mm Heat Shrink Tubing Black (1 Meter)

2.5mm Heat Shrink Tubing Black (1 Meter) is a high-quality, durable, and flexible insulation solution designed to protect and reinforce electrical connections, wires, solder joints, and electronic components. Whether you are a hobbyist, technician, engineer, or DIY enthusiast, this heat shrink tube offers a professional-grade finish with excellent electrical insulation and mechanical strength. Its uniform shrinkage, flame-retardant material, and long-lasting build make it ideal for a wide range of applications in electronics, automotive wiring, aerospace, and industrial equipment.

With a 2.5mm inner diameter before shrinking, this tubing is perfect for thin wires, sensor cables, jumper wires, and delicate soldered joints. Once exposed to heat—using a heat gun or similar tool—the tubing shrinks tightly around the wire, ensuring strong strain relief and protection against wear, abrasion, and environmental exposure. The black color provides a clean and professional appearance, making it suitable for cable management, repairing damaged insulation, or marking specific types of wiring.

Designed for ease of use, this tubing is made from high-quality polyolefin material known for its durability, flexibility, and high temperature resistance. Whether you need to insulate individual wires or bundle small groups of cables, the 2.5mm heat shrink tube ensures efficient and reliable performance every time.
