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

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

The Boshart HSC-4 is a 4-wire clear heavy duty heat shrink splice kit designed for wire connections in the #14-10 AWG range. Built from flexible cross-linked polyolefin heat shrinkable tubing, this kit is rated for applications up to 600 volts and is engineered to deliver waterproof insulating protection and environmental sealing at splices, connections, and jacket repairs. The heavy wall tubing construction gives the kit high impact and abrasion resistance, making it a durable choice for demanding installation environments where mechanical protection matters as much as electrical insulation. Each kit is packaged 50 ea and manufactured in Canada, giving installers a ready supply of splice protection material for rough-in and repair work.

Key Features

• Wire Range: Sized for #14-10 AWG wire, matching common branch-circuit and control wiring gauges.
• 4-Wire Configuration: Kit is configured to splice and protect four wires per assembly.
• Durable Construction: Flexible cross-linked polyolefin heat shrinkable tubing provides high impact and abrasion resistance for long-term mechanical durability.
• Voltage Rating: Suitable for applications up to 600 volts.
• Waterproof Sealing: Provides excellent waterproof insulating and environmental sealing protection for splices, connections, and jacket repairs.
• Shrink Ratio: When heated above 120°C (250°F), the tubing shrinks at a 3:1 ratio to conform tightly around the splice.
• Clear Tubing: Clear construction allows installers to visually verify the splice connection beneath the shrunk tubing.
