Our oring groove design guides list default oring groove dimensions for the most basic applications and are intended to be used with the following oring groove design considerations to engineer on oring gland to optimize specific application performance The wrong size groove makes even the best oring underperformThe Oring may be housed in a groove (rod seal) in the cylinder wall instead of a groove in the piston surface (piston seal) without any change in design limitations or seal performance Oscillating A valve spindle is an example of an oscillating applicationTested in face type Oring seals using grooves that provided 15%, 30% and 50% compression For vertical Oring applications (as a chamber), it is desirable to use an undercut groove similar to that shown in Figure 1 The Oring is held firmly in place and has no tendency to drop out of the groove when the chamber is open Figure 1
The oring gland design is more complex for radial seals and requires both the piston and the bore to have precise geometry The bore and the piston have to be concentric to one another One of the faces will be completely smooth and one will have an oring groove cut into it;AS568B STANDARD ORING GROOVE DESIGN Contact Us For Assistance Or Samples Click Here and contact us today to receive a quote or if you have any questions regarding sizing × Dismiss alert The three main types of standard groove designs are Industrial Static also called Radial, Industrial Reciprocating also called Dynamic, and Face Seals alsoStatic Radial ORing Gland Design In a static radial seal application the oring is squeezed between the inner ID and the outer OD surfaces of the oring, with no relative motion between parts of the gland that come in contact with the oring The table below lists recommended dimensions for static radial seal glands by AS568A oring dash
To compress an Oring of 533 mm thickness by %, approx 5 N per mm of sealing length is required for a hardness of 70 Shore A resp 7 N/mm for 80 Shore A To facilitate assembly, the diameter of the Oring groove is usually selected somewhat larger than the diameter of the Oring This keeps the Oring in the groove during assemblyGeneral Engineering Menu ORings Suppliers Molded ORings Services ORings Design Guidelines, Specifications, Materials An Oring , also known as a packing , is a flexible gasket in the shape of a loop;Now, 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

The groove is in the 'ceiling' of the application, so I want that the oring is compressed into the groove to prevent it from falling out when the seal is opened The inside circumference needs to be sufficiently small to provide space for the oring to be squeezedClick here for more information on face seal groove design Note the ORing inside diameter for the next step Calculate the Seal Stretch Using Equation 1, calculate the installed seal stretch If the installed seal stretch is greater than about 3%, you may have to select the next larger ORing or require a custom ORing for your applicationThe ERIKS Oring design calculator features the calculation of • oring dimensions for the use in a specific groove • groove dimensions for the use of a specific oring • evaluation of both, any combination of oring and groove for axial seals with inner or outer pressure, piston seals and rod seals

When designing such a seal to receive a standard Oring, the inside corner radii of the groove should be at least three times (ideally six times) the crosssection diameter of the Oring to avoid overstressing the ring or causing corner creases that would potentially leakORing 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, EMIDesign dimensions for oring installation Orings are normally used as seals in several ways, and dimensions of the groove or gland will also vary with the cross section of the ring, the type of
