O ring design guide metric

The info is based on 70 Shore A Durometer hardness only. Featuring dimensions for metric cylinders and face seal flange grooves. This can allow more streamlined maintenance and shorter downtime with less effort required to secure the seal during installation. Especially handy if the face seal is assembled upside-down.

O-Rings are solid-rubber , doughnut-shaped seals used to block the passage of a gas or liquid when pressed between two mating surfaces. They are amongst the most widely utilized seal designs in the world. Due to the number of ways they can be utilized, there are essentially an endless number of O-Ring sizes. This creates a boundary to keep fluids in and contaminants out. The wide ranges of ID dimensions of O-Rings are developed around standard inch fractional sizes.

Global O-Ring and Seal has developed o-ring groove design and gland dimension guidelines. The o-ring cross-section in your design will determine all your subsequent dimensions and specifications. Standard o-rings are available in various cross-sections and inside dimensions ID. Below, is a list of advantages in the selection of smaller and larger cross-section o-rings. The ID or OD of the o-ring should be sized to create some interference, per the guidelines below:. Below, four standard application groove design guidance tables are presented along with dimensional reference drawings. The first table is for industrial face or flange seals. The second table is for static industrial radial applications. The third table is for dynamic industrial reciprocating applications. Lastly, the fourth table is for dovetail groove design. These o-ring groove design guides offer default dimensional guidance for basic o-ring groove design applications. A flange or face seal is static and will not have a gap between surfaces, eliminating any design issues associated with extrusion.

An O-ring groove is a circular cross-sectioned recess in a housing or mechanical device designed to hold an O-ring seal. The O-ring sits in the groove and is compressed during assembly, creating a seal between two surfaces. O-ring groove design is critical to the performance of the O-ring seal. When designing an O-ring groove, it is essential to consider all these factors to ensure an effective seal. O-rings are available in various materials, sizes, and cross sections to meet the needs of most applications. O-ring compression ratios can vary depending on the application. At Allied Metrics , we can assist with O-ring groove design and O-ring selection to ensure a successful application.

Secondly, the o-ring is at its smallest cross-section tolerance limit and the gland is at its largest size tolerance limit. Share on Twitter. Especially handy if the face seal is assembled upside-down. O-ring material selection guide. However there is very little void space and volume swell can easily lead to extrusion failure. Metric O-Rings are manufactured using various materials, such as synthetic rubbers, thermosets, and elastomers, each chosen based on factors like chemical compatibility, temperature range, sealing pressure, lubrication requirements, durometer, size, and cost. Backup rings are designed to eliminate the extrusion gap in high-pressure sealing applications. O-Ring Groove Design Guides Expert Application Engineering Assistance O-ring groove design guides offer default dimensional guidance on the most basic o-ring groove design applications. Custom o-rings are available upon request and can typically be produced within a few weeks with no tooling fees. Responsive expert service. However, The O-Ring Store, LLC makes no warranty, expressed or implied, that parts supplied in this material will perform satisfactorily in specific applications.

O-ring groove design guides offer default dimensional guidance on the most basic o-ring groove design applications. The best o-rings are useless without the right groove design which becomes increasingly important the more demanding the application environment.

Metric O-Rings are manufactured using various materials, such as synthetic rubbers, thermosets, and elastomers, each chosen based on factors like chemical compatibility, temperature range, sealing pressure, lubrication requirements, durometer, size, and cost.

We offer the largest inventory of specialty and standard sealing solutions backed by best-in-class technology, service and support. January O-ring material recommendations. Finding the Right O-Ring Cross-Section The o-ring cross-section in your design will determine all your subsequent dimensions and specifications. Next Gaskets for Damping Vibration. Another alternative is to use backup rings which are anti-extrusion elements. For non-standard o-ring sizes, check out the Parker 5-Dash Series on our website. O-Ring Extrusion Extrusion is a concern for radial seals where a designed gap exists between moving components: Either the piston and bore, or the rod and bore. To ensure the proper amount of squeeze needed for an adequate seal, the O-Ring cross section needs to be larger than the height of the gland. Backup Ring Layouts Backup rings are designed to eliminate the extrusion gap in high-pressure sealing applications.
