Gardner Bender HST-AST Heat Shrink Tubing 4 in

Product Description

The GARDNER BENDER HST-AST is a 4-inch heat shrink tubing designed for electrical insulation and protection tasks in the field. With a 2-to-1 shrink ratio, it forms a smooth, tight-fitting sleeve over the work surface, providing a high degree of flexibility once set. Heat is applied below 200 degrees F to activate the shrink. Licensed electricians and maintenance technicians reach for this tubing when repairing damaged insulation, building strain relief, or restoring cord integrity on tools and appliances.

This tubing suits a wide range of residential and commercial applications. Common uses include repairing electrical cords on power tools and appliances, adding or restoring handle grips on hand tools, bundling wire runs, and providing abrasion protection on wire harnesses. Its flexibility after shrinking makes it appropriate for installations where the finished assembly must flex during normal use. The 2-to-1 ratio accommodates most standard wire and small-diameter rod or tubing sizes encountered in typical electrical service work.

Key Features

• 2-to-1 full shrink ratio forms a smooth, tight-fitting insulation layer
• High flexibility after shrinking suits dynamic and flexing applications
• Activates with heat applied below 200 degrees F using a heat gun or similar tool
• 4-inch length provides a workable segment for cord repair and grip applications
• UL listed and CSA approved for use in listed electrical applications

Compatibility

Designed as a general-purpose heat shrink tubing suitable for electrical cord repair, hand tool grip restoration, and wire insulation on standard-diameter conductors and assemblies encountered in residential and commercial electrical work.

Installation Notes

Installation is performed by electricians and maintenance technicians working to NEC guidelines for insulation and conductor protection. De-energize and disconnect any circuit or tool before applying heat shrink tubing. Use a heat gun or similar controlled-heat tool and apply heat evenly around the tubing, keeping the heat source moving to avoid scorching. Do not exceed 200 degrees F during application.
