Gardner Bender HST-500 Heat Shrink Tubing 0.5x4 in

Product Description

The GARDNER BENDER HST-500 is a heat shrink tubing designed for electrical insulation and repair work across a wide range of applications. At 0.5 inches in diameter and 4 inches in length, this tubing delivers a 2-to-1 shrink ratio, collapsing down to form a smooth, tight-fitting sleeve over conductors, terminals, and grip surfaces. The result is a flexible insulating layer that protects against abrasion, moisture ingress, and incidental contact. Electricians and maintenance professionals reach for this tubing when restoring damaged cord jackets, insulating splice points, or rebuilding handle grips on hand tools. UL listed and CSA approved, the HST-500 meets recognized standards for electrical insulation applications.

The HST-500 suits residential and light commercial electrical work, tool and appliance repair, and general-purpose wire management tasks. Common use cases include repairing frayed cords on power tools and appliances, covering crimped terminals, and adding protective sleeves to hand tool handles. The 4-inch cut length is practical for single-conductor repairs and short-run insulation jobs without requiring the installer to cut down from bulk stock. The tubing is sold in packs with a minimum order quantity of 6 units, making it a cost-effective stocking item for service vans and shop benches.

Key Features

• 2-to-1 shrink ratio creates a smooth, tight fit over most conductor and terminal profiles
• High flexibility after shrink maintains serviceability in dynamic or vibrating installations
• 0.5-inch pre-shrink diameter accommodates a broad range of cord and terminal sizes
• 4-inch length suits single-splice and short-run insulation tasks without trimming
• UL listed and CSA approved for recognized electrical insulation service
• Apply heat below 200 degrees F to activate shrink without damaging adjacent components

Compatibility

Designed as a general-purpose heat shrink insulation sleeve suitable for electrical cord repair, terminal insulation, and handle grip restoration on hand tools and appliances where a 0.5-inch pre-shrink diameter and 2-to-1 shrink ratio provide adequate coverage.

Installation Notes

Installation is typically performed by electricians or qualified maintenance technicians. Always de-energize and lock out the circuit before applying heat shrink tubing to any conductor or terminal. Use a heat gun or similar controlled heat source and keep the applied temperature below 200 degrees F to achieve full shrink without scorching the tubing or adjacent materials. Do not use an open flame, as uncontrolled heat can damage the tubing and surrounding insulation.
