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 ...
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.
The recessed region is bounded by a deep choke trench (or ditch or groove) cut into the face of the flange. Choke flanges are only used with rectangular waveguide, and are invariably pressurizable, having a gasket groove encircling [3] the choke ditch. The presence of these two concentric circular grooves makes choke flanges easily recognizable.
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.

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.
A gasket (orange) used as a face seal to prevent flow from escaping from a pipe flange joint. In mechanical engineering, a face seal is a seal in which the sealing surfaces are normal to the axis of the seal.
