Oring seals are described in this section under "Scope of ORing Use" Orings are also used as lightduty, mechanical drive belts More information, including design criteria on Oring drive belts and their application will be found in ORing Applications, Section III 12 What is an ORing Seal?Designing the parts of an application where orings will be applied is termed "oring groove design" In order to seal properly, the oring has to deform in the application by being compressed and stretched in any number of waysNow, follow the steps below to design your own oring seal and oring groove Step 1 Choose your rubber properties by going to our Oring Material Guide section Step 2 Make sure that the material you choose will withstand the temperature of your system by going to this rubber temperature range chart Step 3
Machining Specifications ORing Design Guide ORing Gland Types Orings are primarily used to prevent the loss of a fluid or gas However, Orings can be used as dust seals, drive belts or on rotating shafts Most Oring seals can be classified into one of the three arrangements shown below ORing CrossSection Advantages of Smaller CrossOring reuse reusing an oring in an assembly after some time in service is generally not recommended Is the oring deformed, cracked, harder than when new, discolored, or less than clean?Preliminary Oring Design Considerations An oring is a simple and versatile ring shaped packing or sealing device Having a circular cross section that functions as a seal, in both static and dynamic applications, by being compressed between the mating surfaces comprising the walls of the gland, in which it is installed
'O' Ring Guide High Performance Sealing Technology The comprehensive guide to 'O' ring sealing systems including • 'O' ring selection • General & high performance materials • Housing design & tolerances • Cords, kits & lubricants Issue 7When designing oring glands, by far the two best resources out there are put out by Parker and Apple Rubber For standard design applications you cannot beat the Parker Oring Handbook, that goes into extreme depth on dimensions and applicationsFor applications that you cannot get the standard gland dimensions on, or that you do not need 5,000 psi of sealing reliability use theThe groove design allows the Oring to be retained in the face seal during assembly and maintenance This is beneficial for special applications where the Oring has to be fixed by the groove eg a lid which opens regularly Bosstail The Oring is used for sealing straight thread tube fittings in a boss
