SURVIVE HOSTILE CONTROLS ENVIRONMENTS
Unsealed electromechanical switches and circuit breakers offer limited environmental protection against harsh contamination penetration. The switches and breakers might be on oil platforms in the Gulf of Mexico, the Permian Basin, the Bakken Shale, petrochemical plants, refineries in Louisiana, in the Arctic or in the Antarctic. No matter the location, care must be taken with this sensitive equipment...

SELF-SEALING FASTENING WITHOUT CHEMISTRY
Wherever secure sealing under pressure (as well as fastening) has been required, dry, embedded 0-ring sealing fastener technology (with optional thread locking) versus wet, liquid adhesive thread locking have been the choices for pump manufacturers and users for more than half a century...

EMBEDDED O-RING SELF-SEALING FASTENERS vs. THE OLD STANDBYS
When gas or liquid are under pressure, system fasteners should be sealed to prevent leakage. This is true even for fasteners that are not under pressure, but where hostile environments such as water, gas, dust, lubricants, cleaning solvents, etc. are present and could penetrate past threads and leak onto the internal mechanism/operating area creating havoc. Fastener users have a number of sealing options to effectively block these contaminants and to contain fluids under pressure (internal/external) ...

SWITCHES & CIRCUIT BREAKERS:
TO HERMETICALLY SEAL OR NOT

Not every unsealed or sealed panel switch, potentiometer, or circuit breaker needs environmental exposure protection from adverse conditions on the ground, in the air, or on or under the water. But for those controls that must operate where dust, dirt, moisture, water, lubricants, fungus, snow, ice and extreme temperatures prevail ...
