O-rings are available in various metric and inch standard sizes. Sizes are specified by the inside diameter and the cross section diameter (thickness). In the US the most common standard inch sizes are per SAE AS568C specification (e.g. AS568-214). ISO 3601-1:2012 contains the most commonly used standard sizes, both inch and metric, worldwide.
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. This is ...
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.
Non-metallic gaskets are used with flat- or raised-face flanges. Spiral-wound gaskets are used with raised-face flanges, and ring-joint gaskets are used with ring-type joint (RTJ) flanges. Stress develops between an RTJ gasket and the flange groove when the gasket is bolted to a flange, leading to plastic deformation of the gasket. [4]
Standard sizes are indicated by the nominal inner diameter in millimeters for flanges 10 through 50 mm in diameter. [2] Sizes 10, 20 and 32 are less common sizes (see Renard numbers ). Some sizes share their flange dimensions with their respective larger neighbor and use the same clamp size.
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.
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.
M18x1.5 parallel thread, which is sealed by an O-ring, and torqued to 100 to 130 N⋅m (74 to 96 lbf⋅ft) on steel cylinders, and 85 to 100 N⋅m (63 to 74 lbf⋅ft) on aluminum cylinders; [22] 3/4"x14 BSP parallel thread, [ 23 ] which has a 55° Whitworth thread form, a pitch diameter of 25.279 millimetres (0.9952 in) and a pitch of 14 ...
