O ring design guide metric

Metric O-Rings are a type of mechanical gasket used for sealing applications.

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.

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. Review the general o-ring groove design considerations before moving onto the specific o-ring gland design type. Engineering support services are available for a fee for expert help optimizing critical applications. X-Ring Seals and high performance O-Ring material groove design follows the same principals as basic O-Ring applications, although require even more attention to design adjustments for specific application environments for optimal sealing performance and life.

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. Types of O-ring Grove Design Standard O-ring groove The Standard O-ring groove is typically used in applications where there is a need for a static seal, such as in hydraulic systems. Dynamic sealing applications use this groove, such as in pneumatic systems.

O-Rings are solid-rubber , doughnut-shaped seals used to block the passage of a gas or liquid when pressed between two mating surfaces. The info is based on 70 Shore A Durometer hardness only. Half Dovetail Groove. They are employed in both static and dynamic applications, such as fluid or gas sealing in pumps, hydraulic systems, automotive components, machinery, and more. However there is very little void space and volume swell can easily lead to extrusion failure. Due to the number of ways they can be utilized, there are essentially an endless number of O-Ring sizes. The overall design of the sealing system must take into consideration this design gap. This metric o-ring groove design reference guide will help you find the right radius, back-up, pressure and other o-ring dimensions for basic applications. Another factor related to O-Ring size is cross section. Below, is an extrusion chart providing the pressure limits by gap and durometer of o-ring. Send us a Message About Your Project. Proper cross section design depends on the size of the gland. In the calculation above, we used the nominal or stated dimensions. Search Close this search box. There will always be a gap between the two surfaces.

As your value-added partner, ERIKS offers the technical expertise to provide customized solutions to your sealing requirements. This manual can be downloaded per section using the below table of contents of completely in the documentation section.

Sorry, no results found. If the pressure is from a single direction, only one backup ring is necessary. Responsive expert service. Backup Ring Layouts Backup rings are designed to eliminate the extrusion gap in high-pressure sealing applications. Some of the most common materials used for metric O-Rings include:. Reset Filters. Surface Finish Generally surface finish for sealing surfaces are as follows… 63RMS maximum: For non-critical sealing surfaces such as groove sides 32RMS maximum: For static sealing on critical sealing surfaces such as groove base and top. Standard o-rings are available in various cross-sections and inside dimensions ID. Non-Standard Size O-ring Sizes We have millions of o-rings in stock or they con be made to order in a few weeks without tooling fees. We offer a selection of specialty formulated o-rings for peak performance in high temperature applications. These o-ring groove design guides offer default dimensional guidance for basic o-ring groove design applications. They are commonly used in applications requiring resistance to high and low temperatures, as well as in medical and food-grade applications. The addition of backup rings should be incorporated in the fill calculation for determining the groove width.
