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 5,000 psi (34 MPa) of pressure The maximum recommended pressure of an Oring seal depends on the seal hardness and gland clearanceThe Different Between O'Ring Boss and O'Ring Face Sealing SAE FittingsRG Group650 North State StreetYork, PA https//wwwrggroupcom/Boss ORings for All Applications Ace Seal can provide Oring boss seals in the size, profile, material, durometer, and color you need However, please note that not every combination of these factors is possible—for example, certain materials are not available in certain durometers, certain durometers are not available in certain colors, etc
O-ring boss seal design
O-ring boss seal design-Oring Boss ports (ORB) provide a seal by trapping the fitting's Oring inside a port cavity When a fitting is installed into the port, the Oring is trapped between the fitting body hex or washer and port cavity Straight fittings include a hex, and sometimes an additional cylindrical shoulder below the hex and above the threads, to trapOring and Seal Design Theory The use of an oring as a seal is mainly to prevent the transfer of fluid (liquid, solid or gas) between two or more regions The components of the seal are the oring itself and the contact surfaces The elastomeric oring relies on a compressive force acting on the oring to prevent the transfer of fluid between
About the Seal Glossary;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 Oring is used for sealing straight thread tube fittings in a boss A boss is a cylindrical projection on a casting or forging The end of that projection is machined to provide a flat, smooth surface for sealing Straight threads used with an Oring provide a better seal than tapered threads used alone
The housing dimensions for static radial sealing Orings are listed in the size lists Housing groove edges All housing groove edges should be smoothed and rounded off ( fig 1 , fig 2 ) to r = 0,1 to 0,2 mm (0004 to 0,008 in)A perfectly designed Oring seal is of little use if the Oring is damaged during installation To prevent installation damage for pistontype and rodtype seals, we recommend a 15°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
Boss, Face, and Flange ORings Overview Used commonly in hydraulic settings, Boss orings, ORing Face Seals, and Flange orings are relied on to provide an efficient, secure seal in highpressure applications All three types have their own specific set ofORing Seal Design AppleGland Design, Oring and Other Elastomeric Seals, Static Applications AS5857 This SAE Aerospace Standard (AS) provides standardized gland (groove) design criteria and dimensions for elastomeric seal glands for static applications The glands have been specifically designed for applications using SAE AS568 size Orings at pressures exceeding
