WebA sealing application in which there is no movement is termed a static seal. Examples include the face seal in an end cap, seals in a split connector, and enclosure cover seals. A sealing application in which there is linear motion (reciprocation) or relatively slow rotation or oscillation, is termed a dynamic seal. WebMar 15, 2024 · Dynamic.

WebDynamic O-Ring Sealing . Dynamic O-ring sealing applications are considerably more involved than static applications due to the implied motion against the O-ring seal interface. Resistance to fluids must be more carefully scrutinized than in conventional static seal designs since a volumetric increase in the O-ring in excess of approximately 20% may … WebIn the case of dynamic seals, the material should not abrade the o-ring during movement as it will cause the o-ring to tear. However, in static seals where the o-ring doesn’t move, …
WebMar 16, 2024 · D-Ring seals. D-ring seals (or D-rings) are another style of homogeneous radial seals consisting of flat bases and a rounded sealing surface, creating a cross sectional geometry similar to a capital “D” (Figure 5.b.). These seals are used in very similar applications to the double chamfer seals, mostly in static and reciprocating applications. WebThe seal contact pressure vs fluid pressure chart clearly shows that the maximum operating fluid pressure of 1500 psi is less than the contact pressure for all O-rings. So leakage will not be an issue. Notice, the static O-ring seal # 2 has larger contact pressure compared to the two dynamic seals due to a larger squeeze in static O-rings.
