But some sacrifice must be made in the pressure limitations of the seal and also in the life of the sealFor a bore (piston) seal QuadRing® Brand Groove Diameter = Max Bore Diameter – (2 X Recommended Gland Depth) For a face seal QuadRing® Brand Groove Depth = Recommended Gland Depth – Application Clearance With a face seal, if the two surfaces to be sealed are in direct contact (such as with a cover), the seal groove depth is simply theOring seal The tables at the right and the diagram below provide the recommended gland design parameters In addition, the gland surfaces must be free from all machining irregularities, and the gland edges should be smooth and true and free of nicks, scratches, and burrs A perfectly designed Oring seal is of little use if the Oring

Static oring face seals, used for a wide variety of applications, come in many shapes and forms Whether you need bolted flanges or removable lids, this oring face seal groove design guide will help you choose the right oring for your application ORing Size Charts Oring, xring and square ring size chartsThe 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 sealsOring and gland — constitute the classic Oring seal assembly Groove Bore
Be it dynamic or static operation, radial or axial loading, vacuum or high pressureGland Design Utilizing Kalrez® ORing Compression Experience with Kalrez® seals has shown that an installed compression (ambient temperature) of 12–18% is suggested for maximum seal life Excessive compression on the Oring seal may result in cracking or splitting of the Oring especially if the Oring is exposed to high temperatures whereAs shown in above figure, an Oring also gets compressed axially in a dovetail groove The groove design allows the Oring to be retained in the axial/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
Parker's SealLok ORing Face Seal offers a leakfree seal fitting design and a rugged construction to make it optimal for use in situations with highpressure, vibration and impulse environments WARNING This product can expose you to chemicals including Lead and Lead Compounds which is known to the State of California to cause cancer andIf you are designing a face seal, select the ORing with an inside diameter which will position the ORing on the side of the groove opposite the pressure Click here for more information on face seal groove design Note the ORing inside diameter for the next step Calculate the Seal StretchWARNING Gland Depth x Groove Width (area of the gland) must be larger than the cross section area of the oring (Pi x R^2)Otherwise many bad things will happen to your design Make sure the squeeze % is sufficiently high enough to seal, but low enough to allow dynamic movements

Seal assembly consists of an elastomer Oring and a gland An Oring is a circular crosssection ring molded from rubber (Figure 11) The gland — usually cut into metal or another rigid material — contains and supports the Oring (Figures 12 and 13) The combination of these two elements;Gland Design for Static Application for Orings with Axial Squeeze Surface Finish X groove top and bottom for liquids X = 32 micro inches (08 μm Ra) • Gland Dimensions Static ApplicationFace Seal GlandsMetric W Oring Cross Section E Gland Depth FOring Groove Design in 3 easy steps Step 1 Choose whether you are working with existing hardware or designing new hardware Select the type of Oring groove piston, rod, face seal or trapped seal If the Oring size required is known, simply select the AS, BS or ISO standard (such as AS568) and enter the dash size reference

Reciprocating seals may be designed so as to permit or prevent rolling of the ring within the groove When the ring is allowed to roll within the groove, the breakaway force necessary to move the piston is usually lower;QUALITY SEALS GROOVE DIMENSIONS AND MACHINING CONSIDERATIONS 3 Grooves for Static vs Dynamic Seals A Static seal grooves are normally designed to have Between 15%25% squeeze on the ORing Static seals can tolerate higher volume swell of the O Ring than dynamic sealsDesigning Oring seals for low pressures, therefore, is not simply a matter of reducing the amount of squeeze it involves a delicate balancing of material hardness, dimensional tolerances, stress relaxation, and friction characteristics Material Hardness The initial phase of designing a lowpressure Oring seal is the same

One general guideline for good Oring application and design is to maintain a range of % sqeeze on the Oring (~1040% for static and no more than 30% for dynamic) No less than 75% of the seal crosssection should be contained within the groove to ensure the seal does not "roll" or extrude out of the grooveThe three main types of standard groove designs are Industrial Static also called Radial, Industrial Reciprocating also called Dynamic, and Face Seals also called Axial or Flange Radial and Dynamic seals require the presence of a diametrical clearance gap for installation1 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)

Dovetail grooves are used to hold the Oring in place during installation or maintenance This groove design is relatively uncommon as it is expensive to machine and should not be used unless absolutely required The dovetail groove construction is only recommended for Orings with cross sections of 139 inch (3,53 mm) and largerRubber Seals, Sealing Devices & ORing Seal Design AppleThe 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 Handbook
