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 ...
