O-ring groove design guides offer default dimensional guidance on the most basic o-ring groove design applications. O ring design guide metric 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.

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. However, due diligence is required when designing a dovetail groove due to limited void space compared to a conventional square groove. This problem can be aggravated by volume swell.

Metric O-Rings are a type of mechanical gasket used for sealing applications. They are a specific variation of O-Rings, which are mechanical seals in the shape of a torus with a round cross-section. Metric O-Rings are designed with standardized dimensions based on the International Organization for Standardization or ISO , making them suitable for applications that follow metric specifications. 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. Some of the most common materials used for metric O-Rings include:. They are known for their low gas permeability, resistance to aging and ozone, and self-extinguishing properties. FKM materials have varying compositions and fluorine content, providing improved chemical or temperature resistance in specific applications. Special formulations of EPDM are suitable for use with glycol-based brake fluids. They are commonly used in applications requiring resistance to high and low temperatures, as well as in medical and food-grade applications. These are just a few examples of the materials used for metric O-Rings, and there are other options available depending on specific application requirements. Metric O-Rings find widespread use in various industries and applications where sealing is necessary. They are employed in both static and dynamic applications, such as fluid or gas sealing in pumps, hydraulic systems, automotive components, machinery, and more. The use of metric dimensions allows for compatibility with international standards, making them suitable for applications worldwide.

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:.

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.

First, the o-ring is at its upper tolerance limit and the gland height is at its lower tolerance limit. They are commonly used in applications requiring resistance to high and low temperatures, as well as in medical and food-grade applications. The best o-rings are useless without the right groove design which becomes increasingly important the more demanding the application environment. Latest Blog Posts. These will produce the highest compression and lowest compression percentages. These o-ring groove design guides offer default dimensional guidance for basic o-ring groove design applications.

However there is very little void space and volume swell can easily lead to extrusion failure.

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.

This accommodates standard industrial hardware shaft and bore sizes. Thousands of common metric o-rings and non-standard o-rings in metric sizes are available in stock. Copyright Marco Rubber and Plastics. 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 second table is for static industrial radial applications. First, the o-ring is at its upper tolerance limit and the gland height is at its lower tolerance limit. O-Ring Tolerances Molded Tolerances Standard o-ring tolerance charts, x-ring tolerances, molded rubber tolerances, extruded tolerances and rubber sheet tolerances. Website by Highland Creative.
