Ecm Industries Llc HST-AST Assorted Heat Shrink Tubing 8 Pk

Product Description

The ECM INDUSTRIES LLC HST-AST is an 8-piece assorted heat shrink tubing kit designed for electrical insulation, wire bundling, and connection protection in HVAC, electrical, and plumbing service work. The kit includes four pieces at 1/8 inch diameter, two pieces at 3/16 inch diameter, and two pieces at 1/4 inch diameter, covering the most common wire gauge ranges encountered in field repairs. Each piece shrinks when heat is applied, forming a tight, insulating sleeve over splices, terminals, and bare conductors. The total package weight is 0.5 pounds, and the carded format keeps pieces organized and ready for job-site use.

This assorted kit suits residential and light commercial service calls where multiple wire sizes may be encountered in a single visit. Electricians, HVAC technicians, and plumbers reach for heat shrink tubing when terminating low-voltage wiring, repairing damaged insulation, or securing splice connections inside panels, junction boxes, and equipment enclosures. The three included diameters reduce the need to carry multiple single-size rolls on the truck.

Installation Notes

Heat shrink tubing should be installed by a qualified electrician or licensed trade professional in accordance with applicable NEC requirements. Always de-energize and lockout the circuit before working on any conductors or terminals. Apply a heat gun evenly along the length of the tubing to achieve a uniform shrink without scorching the insulation. Do not use an open flame as a heat source, as this can damage the tubing and adjacent components.
