Designing the parts of an application where orings will be applied is broadly 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 waysThe most common design of mechanical face seals is the oring design This design consists of two symmetrically tapered seal rings and two orings The oring style has two versions, the 7690H which has a ground profile, and the 7697 which has an ascast profile In general, both versions are completely interchangeable At installation, the orings are compressed between the Seal & Design can help with expert staff and a broad wide variety of gasketing products and gasket solutions We fabricate hundreds of materials in different material styles Capabilities include Die cut, Waterjet cut, Beaded Gaskets, Pressure Sensitive Adhesive (PSA) laminated parts, Prototyping, Kiss Cut, custom packaging and kitting, and engineering assistance

In static seal operating conditions one must not overlook the fact that important variations of pressure and temperature can cause relative movements between the ORing and the surfaces with which it is in contact, and therefore problems of wear and superficial damage that can compromise the seal For this reason it is a good idea to accurately design the ORing's housing seats andORing Handbook Parker Hannifin ORing Diision Europe ORing Handbook Parker Hannifin ORing Diision Europe Preamble Sealing technology by ParkerPrädifa The Engineered Materials Group of the Parker Hannifin Corporation is the worldwide leader in the field of designing, developing and manufacturing sealing systems, vibration dampers, EMI shielding systems and heatThe face seal design chart below explains the hardware dimensions to use for an Oring seal when the groove is cut into a flat surface For designing systems which contain internal pressure, like the example below, the groove's outside diameter (OD) is primary, and the groove's width then determines the inside diameter Conversely, when designing systems which seal equipment from

Static and dynamic Oring seal design differs in a few key ways A static Oring is any oring designed to contact with two or more surfaces that do not move relative to one another, whereas a dynamic Oring is one that helps form a seal between moving parts On the whole, static orings are created from less robust and hardwearing materials than their dynamic equivalents It's alsoDesign Chart 42 For Industrial ORing Static Seal Glands 1/2 E Male Gland B1 Dia (B1 Min = A Max 2 L Max) C Dia A Dia Female Gland 1/2 E B Dia D Dia A1 Dia (A1 Max = B Min 2 L Max) Refer to Design Chart 42 (below) and DesignTable 42 for dimensions Finishes are RMS values (e) 0° to 5° (Typ) 6 3 63 R 32 G 1/2 E FL Gland Detail Break CornersDynamic seal design and oring failure modes It also provides an overview of international sizes and standards, and compatibility data for fl uids, gases and solids Engineers in every industry choose orings made by Parker Hannifi n to keep their equipment running safely and reliably That's because Parker's ORing Division, a developer, manufacturer and supplier of precision

Orings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements They have been tested to seal up to 5000 psi (35 megapascals) of pressure The maximum recommended pressure of an Oring seal depends on the seal hardness and gland clearance Manufacturing Orings can be produced byThe oring gland design is very simple for face seals Simply cut out a circular groove into one of the plates and leave the other plate completely flat, the groove will have a square/trapezoidal cross section and the dimensions are conveniently already calculated and laid out in tables in the Parker Oring Handbook10 ORING SEALS – THEORY AND DESIGN PRACTICES Theory An oring seal consists of an oring and a properly designed gland which applies a predictable deformation to the oring The gland is basically a groove dimensioned to a certain height "H" and width "W" (Figure 1) to allow a fixed compression of the oring when the gland flanges make metal to metal contact It is also

The tendency of an Oring to return to its original shape when the cross section is deflected is the basic reason why Orings make excellent seals The squeeze or rate of compression is a major consideration in Oring seal design Elastomers may take up the stackup of tolerances of the unit and its memory maintains a sealed condition Orings with smaller cross sections are squeezed Face seals are actually really tricky to get right, because squeezing the Oring requires a great deal of pressure This first lid design is far too thin, and in the middle, there is virtually no squeeze on the Oring, and hence no sealing We can fix this design by adding a lip around the perimeter A third type of design is a boss seal You1 Male or Plug the Oring groove is located on a plug which is inserted into the housing or cylinder (fig 123) 2 Female or Tube the Oring groove is located in the housing or cylinder and a tube is installed through the Oring lD (fig 124) Male or Plug Seal design is based on the following factors (refer to fig 123) Bore Diameter (A)
