Metal Face Seal Fitting Field Study

Multi Mate-Demate Record This report details a Multi mate/demate field study at Lawrence Livermore National Laboratory.  Over six years in service, this fitting was mate/demated 1557 times and was still working effectively when decommissioned. This evaluation shows the direct cost savings by avoiding the replacement of fittings that no longer passed leak check in this […]

ITRS – 22 Nanometer Mode

These findings are in regard to 22 nm circuitry, which is currently in design for 2011-2012.  For this circuitry we will be concerned with all particles >10nm.  There are some new issues that may reveal a need for cleaner, torque elimination metal face seal fittings.  One new challenge is that with these extremely small geometries, […]

Total Fitting Cost in an Assembly

This graph shows the installed cost of an Omnisafe vs the legacy metal face seal fitting. For either fitting, the purchase price is based on quantity. The additional labor cost of legacy fittings occur while trying to keep the components in alignment, undamaged, and leak tight during gas system assembly. Cost avoidance due to torque […]

The Mechanics of Metal Seal Formation

Tribology is the study of friction, lubrication, and wear. Formally defined, it is the science and technology of interacting surfaces in relative motion. A face seal fitting that transfers torque to the sealing surfaces during the compression that creates the seal, has a fundamental flaw. A tribological study of metal seals shows that this rotation […]
