Gardner Bender HST-250 Heat Shrink Tubing 0.25x4 in

Product Description

The GARDNER BENDER HST-250 is a polyolefin heat shrink tubing designed for insulating, protecting, and repairing electrical connections, cord repairs, and tool handle grips. Cut to a 4-inch length and sized at 0.25 inch inner diameter, it features a 2-to-1 shrink ratio that collapses the tubing into a smooth, tight-fitting sleeve over the workpiece. The result is a flexible, durable insulation layer suitable for most electrical repair tasks encountered in the field or shop. Licensed electricians and skilled tradespeople typically apply this tubing wherever a clean, code-acceptable insulation sleeve is needed on conductors, splices, or mechanical grips.

This tubing is suited for residential and light commercial electrical repair work, including restoring damaged insulation on tool cords and appliance leads, building up handle grips on hand tools, and bundling or protecting wire harnesses. Its flexibility after shrinking makes it practical in tight spaces where rigid sleeving would be difficult to route. The 2-to-1 shrink ratio accommodates a range of conductor and connector sizes within the 0.25 inch diameter range, reducing the need to stock multiple sizes for common repair jobs.

Key Features

• 2-to-1 shrink ratio forms a smooth, tight insulation sleeve over conductors and connectors
• 0.25 inch inner diameter fits a range of wire gauges and small connector bodies
• 4-inch length provides enough material for most standard splice and cord repair applications
• High flexibility after shrinking allows routing in confined spaces
• UL listed and CSA approved for use in electrical insulation applications
• Activates at temperatures below 200 degrees F, compatible with a standard heat gun

Compatibility

Designed as a general-purpose heat shrink sleeve for electrical cord repair, splice insulation, and handle grip applications on hand tools and small appliances. Suitable for use wherever a 0.25 inch diameter, 2-to-1 shrink ratio tubing meets project requirements.

Installation Notes

Installation is performed by licensed electricians or qualified tradespeople in accordance with applicable NEC requirements. Before applying, de-energize and lock out the circuit being serviced. Slide the tubing over the conductor or splice before making the final connection, then position it over the area to be covered. Apply heat evenly using a heat gun set below 200 degrees F, working around the circumference of the tubing until it shrinks uniformly — avoid using an open flame, as uneven or excessive heat can damage the tubing or underlying insulation.
