O Ring Groove Design Global O Ring And Seal
Design Guidelines for Axial Seals.
. O-Ring design for axial seals is similar to that for radial seals with the important points summarized below. Crush seal Flange Seal Axial Seal In flange seal glands the two flanges are assembled with metal to metal contact. While it is an effective seal the O-ring is permanently de-.
Also be sure to stretch it uniformly. ID Inside Diameter OD Outside Diameter CS Cross Section 070 103 139 210 275. Designing the parts of an application where o-rings will be applied is broadly termed o-ring groove design.
O-ring volume is usually 90-95. For more than 40 years Marco Rubber and Plastics has been offering custom and standard o-rings and other sealing solutions for multiple industries. Inside diameters range from 0029 to 25940 inches.
Compact need very little space - light weight. A number of common seal types T-Seals U-Cups V-Packing and other devices have been and are still used for both dynamic and static seals. Click here for more information on face seal groove design.
US Japanese JIS British BS and Common Metric o-ring size charts. Static Crush Seal Grooves Triangular Grooves. Review the general o-ring groove design considerations before moving onto the specific o-ring gland design type.
Choose your rubber properties by going to our O-ring Material Guide section. To fit a traditional rectangular O-ring groove into existing space limitations. Crush seals are the third type of o-ring seal and are.
Now follow the steps below to design your own o-ring seal and o-ring groove. An O-ring seal is used to prevent the loss of a fl uid or gas. If you are designing a face seal select the O-Ring with an inside diameter which will position the O-Ring on the side of the groove opposite the pressure.
O-Ring Compatibility O-ring compatibility information for. Flange seal Radial seal Dovetail seal Boss seal. As an aid in assessing the relative merits of an O-ring the.
Before installation make sure to lightly coat the o-ring with a lubricant that is compatible with the o-ring being installed as well as compatible with system chemicals. The O-Ring inner diameter is typically chosen to be close to the grooves. This use of an O-ring is a variation of the static seal.
Note the O-Ring inside diameter for the next step. O-Ring Installation Design and Specification Static Flange Application. There are 369 standard sizes.
With millions of products produced and shipped annually we are the experts your organization needs to seal the success of your application. Is not recommended because it can lead to a loss of seal compression. In some cases an O-ring may even be asked to seal two leak paths between mating parts.
In order to seal properly the o-ring has to deform. The O-ring is crushed into a space having a cross-section differ- ent from that of a standard gland for example triangular. The engineering design guide provided by Ace Seal will help you navigate the wide range of static O-ring applications used for sealing including.
The maximum volume of the o-ring should never surpass the minimum volume of the gland. In order to seal properly the o-ring has to deform in the application by being compressed and stretched in any number of ways. Please contact the local ERIKS repre-sentative if an application does not clearly fall into these design parameters.
For a static crush seal application it is recommended that the o-ring volume does not exceed 95 of the gland void. In these applications a triangular-shaped O-ring groove may be the solution to the design dilemma. A static triangular crush seal groove is a.
Can be used for static and dynamic applications. Design guidelines for O-Rings. Speak with an engineer today at 603-468-3600.
The O-ring is crushed into a space having a cross-section different from that of a standard gland for example triangular. Be it dynamic or static operation radial or axial loading vacuum or high pressure. In piston applications avoid stretching the o-ring more than 100 during installation stretch should not exceed 5 in the application.
A stretch greater than 5 on the O-ring ID. Here is an interactive chart for standard. Flange seal radial seal dovetail seal boss seal and crush seal.
Make sure that the material you choose will withstand the temperature of your system by going to this rubber temperature range chart. As important as the oring seal itself is the groove that the oring seats into. Static Applications There are five types of static O-ring applications.
For these applications a triangular-shaped O-ring groove may be the solution to the customers design dilemma. Using Equation 1 calculate the installed seal stretch. Nibbling and premature wear and seal failure will result.
Calculate the Seal Stretch. In other cases an O-ring may be asked to seal two leak paths between mating parts. Now follow the steps below to design your own o-ring seal and o-ring groove.
The groove must be designed to accommodate not just the oring size but also its intended usage. Contact Ace Seal regarding our static O-rings engineering guide today. Parkers O-Ring Selector is an engineering tool which offers O-ring material and.
For reciprocating seals passing o-rings over ports is not recommended. Crush Installation 179 Crush Installation This use of an O-ring is a variation of the static seal. The O-Ring must be compressed by a predetermined amount and this compression determines the O-Ring cross-section diameter.
Whether you need bolted flanges or removable lids this o-ring face seal groove design guide will help you choose the right o-ring for your application. O-ring volume is usually 90-95 gland volume Figure 1-13. Easy to incorporate into design.
O-ring groove into the existing space limitations. Cross-sectional diameters range from 0040 to 0275 inch. Once your design is complete easily order o-rings online from the worlds largest o-ring inventory network.
Gland Design For Dynamic O-ring Seals. When compared with an O-ring these other seal types may show one or more design disadvantages which might be overcome by use of an O-ring. 859 269-2351 Fax.
Engineering support services are available for a fee for expert help optimizing critical applications. Do not require high accuracy. Design of O-Ring Seals.
O-Ring Installation Design and Specification For Dynamic Applications. Commonly called a crush seal design triangular groove designs have established a proven track record of. The standard sizes are also used for most military specifications.
O-ring Gland Design Dovetail seal Also here there is a metal to metal contact as long as the con-struction will not deform under system pressure. Commonly called a crush seal design triangular groove designs. While it is an effective seal the O-ring is permanently deformed and therefore generally considered non-reusable.
O-Ring Leak Rate Equation and Calculator. O-Ring Size Charts O-ring x-ring and square ring size charts. O-ring Gland Design The following pages contain basic O-ring gland design information.
So in fact there is no remarkable gap and no.
