Gardner Bender Hst-asta Heat Shrink Tubing, 1/4 To 1/8 In., 4 In. L

Gardner Bender heat shrink tubing is a flame-retardant polyolefin solution designed to insulate and protect electrical wire splices, connections, and damaged appliance cords. The tubing resists common fluids, solvents, and moisture, making it suitable for reliable electrical applications where safety and durability matter.

With a 2:1 shrink ratio, the tubing contracts from 1/4 inch expanded diameter to 1/8 inch recovered diameter, allowing it to fit snugly over wires and connectors. Its excellent dielectric strength of 600 volts per mil provides superior voltage resistance for secure insulation. Whether you're repairing power cords, protecting wire splices in tight spaces, or covering tool handles, this tubing delivers reliable performance and long-term protection.

Features and Benefits

• Flame-Retardant Construction: Polyolefin material resists flames and provides exceptional abrasion and moisture resistance.
• Extreme Temperature Range: Operates continuously from -55°C to 135°C (-67°F to 275°F), and shrinks efficiently at temperatures between 120°C and 250°C (250°F and 480°F).
• High Dielectric Strength: Rated at 600 volts per mil for secure electrical insulation and voltage resistance.
• 2:1 Shrink Ratio: Contracts precisely from 1/4 inch to 1/8 inch diameter for a tight, protective fit over wires and splices.
• Chemical and Moisture Resistant: Withstands exposure to common fluids, solvents, and moisture for reliable performance.
• Compact Size: 4-inch length is convenient for various splicing and repair applications.
