Ecm Industries Llc HST-187 Heat Shrink Tubing 3/16 in 8 Pack

Product Description

The ECM INDUSTRIES LLC HST-187 is a heat shrink tubing pack designed for insulating, bundling, and protecting wire splices and electrical connections. Each pack contains 8 pieces of tubing with a pre-shrink diameter of 3/16 inches and a post-shrink diameter of 3/32 inches, providing a 2:1 shrink ratio. This tubing is UL and CSA approved, making it suitable for use in professional electrical, HVAC, and low-voltage wiring applications. Licensed electricians, HVAC technicians, and other trade professionals use heat shrink tubing as a standard method for sealing and protecting terminations and repairs.

This product is used in residential and light commercial wiring work where insulated, durable wire protection is required. Common applications include protecting wire splices, covering butt connector ends, insulating terminal connections, and organizing wire bundles. The 3/16-inch diameter fits a range of wire gauges typically encountered in control wiring, thermostat circuits, and general electrical repair work. The carded packaging keeps pieces organized and ready for field use.

Installation Notes

Heat shrink tubing is installed by licensed electricians and HVAC technicians as part of standard wiring and termination procedures. Always de-energize the circuit before applying heat shrink tubing to any connection. Use a heat gun set to an appropriate temperature and apply heat evenly around the tubing, moving the gun continuously to avoid scorching. Follow applicable NEC guidelines for insulation and conductor protection requirements.
