The WetLink Penetrator (WLP) is our patent-pending, next-generation solution for low-cost, high pressure, high reliability sealing of electrical cables as they pass into enclosures or other devices. It’s rated to a depth of 950 meters (3,116 feet) and compared to subsea connectors or penetrators, the WetLink Penetrator is a fraction of the cost while offering validated reliability that you can count on.

The WetLink Penetrator can be installed in seconds and doesn’t require any adhesives, potting compounds, or rubber molding. It’s the easiest to use solution out there!

The concept behind the WetLink Penetrator is simple: a cable and rubber seal are installed into a bulkhead and then compressed such that a high-pressure seal is formed. That pressure also holds the cable in place and strain relieves it against it being tugged or pulled out.

Despite the simplicity of the concept, we’ve put a lot of attention into the details to ensure absolute reliability. The WetLink Penetrator was put through a rigorous testing and validation process in which we tested thousands of samples through extreme conditions: high pressure, hot and cold temperatures, high electrical current, accelerated aging, and mechanical strain. Our results demonstrate reliability that you can count on in your application.

The WetLink Penetrator can be used on a variety of cables, but the design has been officially tested and validated on specific cables. Our official specifications only apply when used on tested and validated cables, which you can see in the Technical Details tab.

The WetLink Penetrator can be assembled with typical hand tools, but we recommend the WLP Wrench and WLP Assembly Block to ease with assembly, especially if you’ll be putting together more than a few!
