Sparton Technology NEMA 6P Amphibian Enclosures


Our amphibian enclosures meet the harsh NEMA 6P standards required to withstand prolonged submersion in floodwaters. Each enclosure is fully tested under positive air pressure at 5 PSI for 24 hours.

When a situation calls for the need to keep sensitive components safe from water and moisture intrusion, our amphibian enclosures are uniquely suited to the task.

Standard NEMA 6P Enclosure Characteristics

Sparton Technology Corporation's proprietary NEMA 6P enclosures house and protect your sensitive components from water and moisture in a variety of environments. These enclosures can be used in commercial or industrial settings and may be deployed for use in water treatment plants, nuclear plants, flood zones and industries including energy, agriculture, marine and oil and gas. These amphibian enclosures may be used indoors or outdoors.

  • Provides protection in a prolonged submersion, at a limited depth.
  • Protection the external formation of ice.
  • Made from water corrosion resistant materials.


Sparton's Enclosure Designs

Sparton offers two basic standard external flange designs.

  • Mini-Amphibian series enclosures for smaller enclosures
  • Amphibian series enclosures for larger enclosures.

We also offer custom designed internal flange and torpedo style enclosures. By far, our most popular enclosures are the Mini-Amphibian and Amphibian Series. View the Model Specs.

Common to all submersible, amphibian enclosures is our utilization of a series of bolts applying a specific pressure to seamless gaskets.

Standard Ports Available on NEMA 6P Enclosures

These are half couplings welded onto the enclosure faces. The standard method configuration is to put all of these on one end face of the enclosure. These are also called hubs, and they are used to make sealed connections into the enclosure, using rigid conduit with NPT threads and sealing paste.
