O-ring mounting for an ultra-high vacuum application. [11] Pressure distribution within the cross-section of the O-ring. The orange lines are hard surfaces, which apply high pressure. The fluid in the seams has lower pressure. The soft O-ring bridges the pressure over the seams. O-rings are available in various metric and inch standard sizes.
The O-ring groove for sealing the 232 and 300 bar DIN outlet connector to the valve is specified by ISO 12209 standard as having an inside diameter of 12 mm and outside diameter of 17 mm, originally with groove depth of 1.9 mm, increased to 2.0 mm in 2003. The O-ring specification is inside diameter 11.2mm with section diameter 2.65mm.
The ISO large flange standard is known as LF, LFB, MF or sometimes just ISO flange. As in KF flanges, the flanges are joined by a centering ring and an elastomeric o-ring. An extra spring-loaded circular clamp is often used around the large-diameter o-rings to prevent them from rolling off from the centering ring during mounting.
Obturating rings are common in artillery, where the steel or cast-iron casing of the shell is too hard to practically deform to provide a tight seal for the propellant gases. An obturating ring which is called driving band made of a softer material is the standard solution for that problem.
An o-ring boss seal is a technique for joining two fluid-carrying pipes, hoses, or tubing. In an o-ring boss (abbreviated ORB) system, a male-threaded part is inserted into a female-threaded part, providing a mechanical seal. This system differs from others in that a nut is tightened over an o-ring in a chamfered area, creating a fluid-tight ...
The O-ring cavity was not designed properly which let to the pressure concentrated to a small section of the O-ring. —Preceding unsigned comment added by Ginnidorka (talk • contribs) 19:16, 23 April 2009 (UTC) I think the failure was due to grubby, corrupt, pork barrel politicians. Having O rings was unneccesary, an inferior design.
