Submersible NEMA 6, NEMA6P & IP67 / IP68 Enclosures for Marine Environments
Whether it’s surface, underwater or onshore infrastructure SLAYSON® has it covered. Our NEMA 6, NEMA 6P and IP67 / IP68 Enclosures are the perfect choice for marine environments, providing protection of vital hardware from the effects of corrosion and water ingress. SLAYSON®’s NAV-6P Enclosures are widely used in communication, surveillance, weapon and control systems. Our enclosures protect critical equipment against unique threats such as mechanical vibrations, electromagnetic interference from radars and communication antennas as well as external threats such as underwater explosions and corrosion.
SLAYSON® has an extensive range of Metallic and Non-Metallic enclosures to suit most onshore and offshore naval applications, while our NAV-6P enclosures have been engineered specifically for the Defense industry with EMC protection as standard. Our NEMA 6, NEMA 6P and IP67 / IP68 enclosure ranges are ready for immediate installation or modification. Can’t find what you need? SLAYSON® will design and manufacture an enclosure to meet your exact specifications!
Why Naval Engineers Specify SLAYSON®
Electrical enclosures on naval vessels are simultaneously exposed to saltwater and electromagnetic interference. We engineered the NAV-6P Marine Submersible Enclosure to address both threats in a single unit, with EMC/RFI shielding integrated into a submersible housing as a standard feature.
- Dual Gasket EMC Shielding: EMC Dual Gasket Technology (EDGT) using Beryllium Copper provides 360° shielding to MIL-STD-285, keeping interference from reaching sensitive components when radar arrays and communication antennas operate adjacent to sealed electronics.
- Submersible Housing: The NEMA 6P / IP68 housing maintains seal integrity during prolonged saltwater submersion to 15 ft/5 m.
- Combined Protection: Both shielding and submersion ratings are built into the same enclosure rather than requiring separate solutions for each threat.
- COTS Availability: Our naval electrical enclosures are commercially available off the shelf, removing the requirement for facility-specific ISO certifications during vendor qualification.
- Simplified Procurement: For programs on fixed procurement schedules, the COTS designation removes a layer of vendor qualification from the sourcing process.
Naval Electrical Enclosure Applications
Our naval electrical enclosures are specified across surface, onshore, and underwater naval programs.
Surface Vessels
We manufacture the NAV-6P series in 316 stainless steel with EMC shielding. They serve as the standard for surface vessel installations to support combat systems and power distribution in systems that generate continuous electromagnetic interference across adjacent compartments.
Onshore Naval Infrastructure
Our NEMA 6P enclosures are designed for shore-based communications and dockside power systems. They feature the same 316 stainless steel used on vessel-mounted units, which simplifies logistics for bases maintaining both shipboard and shore-side installations.
Support and Auxiliary Vessels
Our enclosures for auxiliary and support vessels are commercially available off-the-shelf. Engineers can specify directly from our standard catalog without a custom design cycle or additional vendor qualification. The protection ratings remain the same as a custom-built unit: NEMA 6P / IP68, MIL-STD-810, and MIL-STD-285.
Submarine and Underwater Systems
Our Subsea series serves applications requiring submersion beyond 15ft, rated to depths of 328ft/100m. These units support battery systems and instrumentation on underwater platforms.
Naval Enclosure Materials and Construction
The environments described above place specific demands on enclosure materials and construction.
Steel and Finish
Our naval enclosures are manufactured in Type 316 stainless steel, 14 gauge (2.00mm), with a #4 polished finish as standard. Alternative finishes include Navy Grey, White, Black, and Anodized Black to meet vessel-specific requirements.
Corrosion Resistance
All seams are continuously welded and ground smooth, eliminating gaps and crevices where saltwater can pool and start corroding the metal from the inside out. The 316 alloy contains molybdenum, which resists pitting and the type of corrosion caused by chloride exposure in marine environments. Every unit is salt-spray-tested to ASTM B117 before it ships. This construction results in fewer corroded units to replace and less downtime for maintenance over the life of the installation.
EMC Shielding
EMC shielding is achieved through our Dual Gasket system. A single-piece Neoprene gasket provides the environmental seal. In contrast, a secondary Beryllium Copper gasket provides 360° electromagnetic shielding around the enclosure perimeter. Both gaskets seat within a single closure mechanism.
Impact and Certification
Impact protection is rated to IK10, equivalent to a 5kg mass dropped from 400mm. All units are tested and certified to IEC 60529 (ingress protection), MIL-STD-810 (environmental endurance), and MIL-STD-285 (EMC shielding performance).

Frequently Asked Questions About Naval Enclosures
Yes. SLAYSON can modify standard enclosure platforms to meet project-specific requirements, including dimensions, mounting configurations, cable entry points, materials, shielding, and other application requirements.
Submersible enclosures are useful for naval equipment installed in locations where wave surge, seawater exposure, or underwater deployment is possible. SLAYSON offers NEMA 6P and IP68 solutions for prolonged submersion, as well as deeper-rated SUBSEA enclosures for underwater applications.
The appropriate NEMA rating depends on the environmental conditions and protection requirements of the application. NEMA 6 and NEMA 6P enclosures provide protection for applications involving water exposure and submersion, with NEMA 6P designed for applications involving prolonged submersion.
SLAYSON enclosures can protect critical electrical and electronic equipment used in naval communication, surveillance, control, combat, power distribution, and other shipboard and shore-based systems. Solutions are available for surface vessels, naval infrastructure, support vessels, and underwater applications.
