Boshart HS-4 4-Wire Heavy Duty Heat Shrink Splice Kit, #14-10 AWG, Black

Boshart HS-4 4-Wire Heavy Duty Heat Shrink Splice Kit, #14-10 AWG, Black

The Boshart HS-4 is a 4-wire heavy duty heat shrink splice kit built for contractors and installers who need a reliable, waterproof wire splice for pump, well, and general wiring connections. Each kit is made from flexible cross-linked polyolefin heat shrinkable tubing rated for use up to 600 volts, sized for #14-10 AWG wire, and finished in black for easy field identification. Designed for use with a heat gun or torch, the tubing shrinks down over the splice to create a tight, environmentally sealed barrier against moisture, dirt, and corrosion at the connection point.

Key Features

• Wire Range: Sized for #14-10 AWG wire, matching common pump, well, and control wiring gauges.
• 4-Wire Configuration: Kit is configured to splice and seal four conductors per kit for multi-wire drop cable and control circuits.
• Voltage Rating: Tubing is suitable for applications up to 600 volts, providing excellent waterproof insulating and environmental sealing protection for splices, connections, and jacket repairs.
• Heavy Wall Construction: High impact and abrasion resistant heavy wall tubing delivers a high level of mechanical durability for buried, submerged, or exposed splice locations.
• 3:1 Shrink Ratio: When heated above 120°C (250°F), the tubing shrinks at a 3:1 ratio to conform tightly around the wire splice and connectors.
• Color: Black finish for straightforward visual identification of completed splices in the field.
