METAL O-RING
SEALS ( EVERGO BRAND ) PROVIDES A HIGH SEALING LEVEL UNDER THE MOST
EXTREME WORKING CONDITIONS WHETHER THE MEDIUM IS GAS OR LIQUID.
-
DESCRIPTION AND APPLICATIONS OF METALLIC "O" RING SEALS
THE EVERGO O-RING SEALS ARE USED WHEN ELASTOMERS AND
OTHER NON-METALLIC SEALS WILL NOT SEAL PROPERLY OR DO
NOT OFFER THE REQUIRED RELIABILITY FOR THE APPLICATION,
USUALLY AS A RESULT OF TEMPERATURES, PRESSURES, OR THE
ENVIRONMENT. EVERGO O-RING SEALS ARE LONG LASTING SEALS
AND UNLIKE NON-METALLIC SEALS, THEY ARE NOT SUBJECT TO
FAILURE DUE TO INCOMPATIBILITY WITH THE ENVIRONMENT, OUT
GASSING OR FROM DETERIORATION DUE TO AGE.
-
EVERGO O-RING SEALS ARE
GENERALLY FABRICATED FROM TUBING CONSISTING OF STAINLESS
STEEL SUS321 OR HIGH TEMPERATURE ALLOYS SUCH AS INCONEL,
OR OTHER MATERIAL AS REQUIREMENT. THESE MATERIALS ARE
FREQUENTLY USED BECAUSE THEY OFFER RESILIENT PROPERTIES
THAT ENABLE THE SEAL TO "SPRING-BACK".
-
WE WELCOME THE OPPORTUNITY TO DESIGN A SEAL TO FIT YOUR
APPLICATION. WHETHER YOU ARE SEALING GASES OR LIQUID -250OC TO 9800C,
10-10
PA TO 300MPA. WE HAVE THE CAPABILITY TO PRODUCE A
SUITABLE SEAL FROM AVAILABLE MATERIAL.

PLATING AND COATINGS
PLATING OR COATING OF THE O-RING SEAL PROVIDES A SOFT
MALLEABLE SURFACE THAT WILL SMEAR INTO SMALL
IMPERFECTIONS IN THE MATING HARDWARE, ENHANCING SEAL
PERFORMANCE.
-
SHAPED SEALS
METALLIC O-RING SEALS CAN BE PRODUCED IN VARIOUS SHAPES.
THE AVAILABILITY OF SHAPED O-RING PERMITS THE DESIGN
ENGINEER TO SELECT THE SHAPES. HOWEVER, WE RECOMMEND
CONTACTING OUR TECHNICAL SERVICE STAFF FOR DESIGN
ASSISTANCE OF SEAL AND GROOVE.

-
APPLICATION CHARACTERISTICS
THE TYPICAL APPLICATION PLACES A METALLIC O-RING SEAL IN
AN AXIAL COMPRESSION BETWEEN TWO PARALLEL SURFACES,
WHICH ARE SQUARE TO THE FLUID PASSAGE OR VESSEL AXIS.
THE SEAL IS USUALLY LOCATED IN AN OPEN OR CLOSED GROOVE
IN ONE OF THE SURFACES. THE SEAL CAN ALSO BE LOCATED IN
A RETAINER, WHICH ELIMINATES THE NEED FOR MACHINING A
GROOVE. THE MATING HARDWARE WHEN BOLTED, TORQUE, CLAMPED
OR FASTENED TIGHTLY TO THE SURFACE ENCLOSING THE RING,
COMPRESSES THE SEAL, FORMING A POSITIVE JOINT
