High pressure o rings Hydraulic O Rings
O Rings used in hydraulic systems, pumps, and other high-pressure applications are often designed to withstand high pressure.
These hydraulic O-rings are made of materials that resist deformation and damage caused by high pressure, ensuring that the sealing system remains leak-free
Hydraulic O Rings Materials:
1.Polyurethane (AU)
2.PTFE
3.Specialty Products4.Buna-N（NBR）-90 shore A
5.HNBR -90 shore A
6.Aflas?
7.EPDM-90 shore A
The system operating pressure is always a consideration as it effects the choice of seal materials in several ways.
Hardness (Durometer)
First is hardness, as may be required to resist extrusion in dynamic designs or where there is a large gap between sealed members in static applications. At very low pressures, proper sealing may be more easily obtained with lower durometer hardness (50-60 shore A). With higher pressures, the combination of pressure and material shore hardness determine the maximum clearance that may safely be tolerated.Second is at-rest vs operating conditions and requirements for “leakless” at rest conditions which would suggest due consideration be given to the long-term compression set properties of a given material.
