• Reduce fugitive emissions of the flange vs. use of metal gasket connection based on patent-pending pressure energized seal design
• Re-usability (condition dependent) of sealring
• No modification to ASME or ANSI flanges needed, sealring fits standard RX or BX groove
• Low sealring setting force (circa 5% of bolt pre-tension) reduces likelihood of seal groove damage during makeup

• Pressure rated up to 15,000 psi

• Temperatures range from –50°C to 250°C (contact FO&GT about higher or lower temperatures)

Example: For a BX 152 Gasket please request an EcoSeal™-BX 152 FO&GT SEALRING

What Can We Do About It?

• FO&GT saw an opportunity to develop and test a sealring that could fit into an existing API flange and would reduce fugitive emissions through petter sealing
• We compared leak rates between standard API 6A and ASME flange connector and sealring with the FO&GT Techlok® and Flangelok® connectors with our proprietary EcoSeal™-BX sealring
• Due to the high volume of connectors at a facility, the cost to replace just the sealring with an FO&GT sealring is more cost effective than replacing the complete connector
• Testing proved our proprietary design is an API qualified metal-to-metal seal that prevents both internal and external leakage of fluids and gases

Based on our test results, if a theoretical quantity of industry standard flanges produced 1,000Kg of CO₂, emissions could be reduced to 0.15Kg using our EcoSeal™ sealring.

Under the test conditions used and the product chosen for comparison, the leak rates for FO&GT metal sealrings are significantly lower than international standards for industrial valves and spiral wound gaskets.
