Thorium Energy Alliance Talk – Multi-Mate / De-Mate Fittings with Torque Elimination

Omnisafe works better than any other fitting for semiconductor applications and has been flight qualified and selected for the following aerospace programs. MSL Mars Rover – launch 2011, for the liquid Freon heat rejection system, Omnisafe 3/8” fittings   JPL DAWN –  Xenon Ion Propulsion,  Asteroid Belt, Oct 2007, Omnisafe 1/8” fittings NASA Evolutionary Xenon…

This is the cross sectional view of the Omnisafe fitting at finger tight (click to enlarge). The gap between the torque eliminators is the same as the gasket thickness (.028”). If the gasket is missing, the torque eliminators bottom out into a “fail safe” mode. This prevents torroid to torroid contact and destruction. The fitting…

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…

Metal gaskets under compression, along a torroidal interface, exhibit plastic and elastic deformation. The elastic deformation is the “spring back” in the gasket indentation that occurs when the fitting is demated. The plastic deformation is remaining the indentation left in the gasket. The elastic deformation is directly proportional to the plastic indention, (i.e. 10%). As…

This is the equipment and procedure used to determine the quantity and size of the particles shed into the process stream, due to galling, as a legacy metal face seal fitting is tightened. Objectives Compare standard metal face seal fitting with the OmniSafe torque suppression fitting over the following criteria: Examine the sealing surfaces of…

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…
