source
6 Factors influencing the quality of sealing
6.1 Surface roughness
6.2 Corner and edge radii
6.3 Lead-in chamfers
6.4 Groove run-out tolerance
6.5 Housing diameter tolerances
6.6 Housing width and depth
6.6.1 Housing width (b)
6.6.2 Housing depth (h or t)
6.7 Stretch and compression o-ring
6.7.1 Radial sealing
6.7.2 Axial sealing
7 Method of calculating housing dimensions
7.1 Radial application - Piston housing
7.2 Radial application - Rod housing
7.3 Axial application - Internal pressure
7.4 Axial application - External pressure
8 Design criteria
8.1 O-ring stretch or compression
8.1.1 Rod housing
8.1.2 Bore housing
8.1.3 Axial housing
8.2 Cross-section reduction
8.3 O-ring squeeze (e)
8.4 O-ring swell
8.5 Housing widths
Gives the design criteria recommended for the housing definition for o-rings as defined in ISO 3601-1, and a calculation method to formulate dimensions of the housing for which the near environment influences parameters in consequence of the definition (seal stretch, squeeze, reduced seal cross-section, swell).
