HydroSplice marine cable splice kits were developed to provide a fast, consistent, and reliable method of splicing underwater electrical cable.


Ordering Information
SubSplice kits may be ordered for the following cables (use the part number shown):
| Conductors | Part Number |
|---|---|
| 2-4 conductor | HS-04-U1 |
| 6 conductor | HS-06-U1 |
| 8 conductor | HS-08-U1 |
| 9-12 conductor | HS-12-U1 |
| 13-16 conductor | HS-16-U1 |
Background
A number of recent technical advances in elastomeric shrink-tube technology have enabled us to put together a new type of marine splice kit.
Advantages
The HydroSplice marine cable splice kit has three advantages over traditional methods of splicing:
- Speed — these splice kits can be installed very quickly, an advantage when working offshore.
- Consistency — installable by anyone with consistent results; there’s very little skill development curve compared to tape splices.
- Reliability — the advanced materials used, and the fact that the shrink tubes are vulcanized in their “recovered” dimensions, mean they retain their grip for many years — long relative to Teflon, which has poor cold-flow characteristics over time.
Components
HydroSplice kits contain everything necessary, including:
- Soldering tubes, clear (1 per conductor)
- Conductor overtubes, clear (1 per conductor)
- Jacket overtube, black (10″–12″)
- Sealing tape
- Solvent cleaning wipe
- Drying wipe
Availability
Splice kits are available for all HydroVolt connectors (2–16 conductor, 18 & 16 AWG). We also offer kits for most other connectors, including coax, twisted shielded pair, and more. Call the factory with your cable specs and we’ll suggest the appropriate kit.
All tubes are sized for both 18 and 16 AWG conductors. The jacket overtube is sized according to the number of conductors. For other wire sizes, coax, shields, or other conductor counts, please call.
Disclaimer
HydroSplice splice kits are intended for professional applications, installed by trained technicians. This is not a consumer product. The advantage of HydroSplice is getting back to work quickly after a cable breakage where time is critical, such as offshore. The splice technician will need a cable holding fixture, a professional heat gun, and — for crimp-type splice kits — a special-purpose crimp tool available from us.
For consumer applications, where time isn’t critical, we recommend either 3M or Raychem kits designed for that use. These take longer since they require cure time, but are better suited for most consumer applications and don’t require special tools.
Even for professionals: if you only need a single splice, we don’t recommend this kit. It takes a number of practice splices to gain proficiency, and the special tools required make a single splice uneconomical.
