Nsi Industries HWHS20-750-9 Heat Shrink Connector 3pk

Product Description

The NSI INDUSTRIES HWHS20-750-9 is a heat shrink wire connector sold in a box of 3. Heat shrink connectors combine a crimp splice with an adhesive-lined polyolefin sleeve that shrinks down over the joint when heat is applied, creating a weatherproof, strain-relieved connection. These connectors are used by electricians, HVAC technicians, and marine or automotive service professionals wherever a sealed, corrosion-resistant wire splice is required. The adhesive lining flows when heated, bonding to the wire insulation and blocking moisture ingress. Each connector in the box provides the same reliable crimp-and-seal performance.

Heat shrink wire connectors of this type are suited for residential, commercial, and light industrial wiring applications where exposed or outdoor splices need protection from moisture, vibration, and contamination. They are commonly installed in HVAC equipment wiring harnesses, outdoor lighting circuits, irrigation control wiring, and marine electrical systems. The HWHS20-750-9 is packaged in a box of 3, making it practical for service calls requiring a small quantity of high-quality splice connectors.

Key Features

• Adhesive-lined polyolefin heat shrink sleeve seals against moisture and corrosion
• Integrated crimp barrel provides a secure mechanical and electrical connection
• Heat activation causes adhesive to flow and bond to wire insulation for a watertight seal
• Packaged in a box of 3 for convenient single-job or service-call quantities
• Suitable for outdoor, marine, and moisture-prone indoor wiring environments

Compatibility

Designed as an OEM-style replacement and general-use heat shrink splice connector suitable for standard stranded or solid copper wire in applicable gauge ranges for this connector series.

Installation Notes

Installation should be performed by a qualified electrician or trained technician in accordance with NEC requirements. De-energize and lock out the circuit before making any splice connection. Strip wire ends to the appropriate length, insert fully into the crimp barrel, and crimp securely before applying heat evenly with a heat gun until the sleeve shrinks uniformly and adhesive is visible at both ends. Do not use an open flame to activate the heat shrink sleeve.
