The WetLink Penetrator is a compression gland cable penetrator to seal electrical cables as they pass into a device or enclosure. Each set includes a bulkhead, seal, plug, O-ring, and nut. It’s rated to 950 meter (3,116 feet) water depth when used with tested cables! We recommend the WetLink Plug Wrench and WetLink Assembly Block to ease with assembly!

Some cable diameters have multiple bulkhead sizes available—make sure to select the correct size for your application! M10 bulkheads fit into the pre-made holes in most of our enclosure end caps, while M6 bulkheads use smaller holes, and M14 bulkheads use larger ones.

Product Description

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. Be sure to refer to our “How to Choose a WetLink Penetrator” guide for a in-depth guide on how to select the right WetLink Penetrator for your cable.

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

WetLink Penetrator Assembly Guide
The WetLink Penetrator (WLP) is our next-generation solution for low-cost, high pressure, high reliability sealing of electrical cables. This guide will show you how to assemble a WetLink Penetrator using our WLP assembly tools or common hand tools.
How to Choose a WetLink Penetrator
Learn how to choose the right WLP size for your cable.
Cable Stripping
Learn how to properly strip cables for use with WetLink Penetrators!

The bulkhead and plug can be re-used reliably up to 3 times. The seal must be replaced each time the penetrator is reinstalled, and the penetrator should be installed on a previously uncompressed section of the cable jacket. Please refer to our WetLink Assembly guide.
