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.

Boshart HSC-4 – Frequently Asked Questions

1) Will the Boshart HS-4 splice kit work on 12 AWG submersible pump drop cable?
Yes. The HS-4 heat shrink splice kit is sized for #14 through #10 AWG wire, so 12 AWG falls in range. It's a 4-wire kit, so it covers a three-conductor-plus-ground drop cable in a single kit.
2) Can this heat shrink splice kit be buried or submerged in a well?
That's what it's built for. The cross-linked polyolefin tubing is heavy wall, impact and abrasion resistant, and shrinks down to form an environmentally sealed barrier against moisture, dirt and corrosion. Listed applications include submersible pump and well wire splicing, underground and buried connections, and wet or damp location splices.
3) What is the difference between Boshart HS-4 and HSC-4?
Color only. HS-4 is the black tubing, HSC-4 is clear. Both are the 4-wire heavy duty kit for #14-10 AWG. Black is easier to spot as a finished splice in a pit or trench; clear lets you see the connector and whether the sealant has flowed at the ends.
4) What voltage can a Boshart HS-4 heat shrink splice be used on?
Up to 600 volts. That covers standard 120V, 240V and 480V pump and control circuits.
5) Do I need a heat gun, or will a torch work on these splice kits?
Either. The tubing is intended for use with a heat gun or a torch, and it starts to shrink above 120 C (250 F), closing at a 3:1 ratio over the splice and connectors. Keep the flame moving if you use a torch so the wall shrinks evenly rather than scorching in one spot.
6) Does the 3:1 shrink ratio matter when I'm splicing over butt connectors?
It does. A 3:1 ratio means the tubing recovers to a third of its supplied diameter, so it goes on loose over a crimped butt connector and still pulls down tight on the smaller bare conductor either side of it. That's the step that gets you a continuous seal rather than a gap at the shoulder of the connector.
7) Can I use this kit to repair a nicked jacket on an existing cable run instead of a full splice?
Yes, jacket repair on existing cable runs is one of the stated uses. The heavy wall polyolefin seals over the damaged section the same way it seals a splice, giving back the moisture barrier and adding abrasion resistance at that point.
8) How many splice kits come in a box of Boshart HS-4?
Packaged 50 each, which is why pump installers and well contractors tend to stock it as a truck item rather than buying singles per job.
9) Where are Boshart heat shrink splice kits made?
Canada. Relevant if you're bidding public or institutional work with country-of-origin reporting on submittals.
