Typical O-ring and application. An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
In the DIN screw thread connectors, the regulator screws into the cylinder valve, trapping the O-ring securely between the sealing face of the valve and the O-ring groove in the regulator. These are more reliable than A-clamps because the O-ring is well protected and the assembly is considerably more rigid, and has a lower profile, making O ...

Both the seal ring and mating must accommodate secondary sealing elements. In some designs, various retainers, sleeves and other components may also include secondary sealing elements. Whereas a simple O-ring might require only a groove for fitting, some secondary sealing elements (for example, packing) might require mechanical compression.
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.
A1: This varies widely by O-ring material and joint design, and also depends (as you might expect) on the lifespan during which you need the O-ring to seal. For common O-ring elastomers, max temps may be expected to be between 100 and 200 degC, with max pressures between 500 and 5000 kPa. Unclben 23:53, 29 October 2006 (UTC)
This canal may receive a circlip, an o-ring, or a gasket. A depression on the entire circumference of a cast or machined wheel, a pulley or sheave. This depression may receive a cable, a rope or a belt. A longitudinal channel formed in a hot rolled rail profile such as a grooved rail. This groove is for the flange on a train wheel.
The movement of the ring packing (RTJ) can be described as an irregular flow in the groove of the deformed sealing flange due to the axial compressive load. Colored seal (RTJ seal) has a small load area, which leads to a large surface pressure between the sealing surface and the groove, the maintenance properties are poor and not suitable for ...
