O ring design guide metric

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.

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.

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. Therefore dovetail grooves are not recommended unless end use conditions and their effects upon the seal are thoroughly taken into consideration. Note: Top radius R is a critical dimension; too small a radius can damage the seal during installation, while excess radius can lead to extrusion failure. It achieves the same sealing efficiency with either internal or external pressure. However there is very little void space and volume swell can easily lead to extrusion failure.

Metric o-ring groove designs vary greatly and choosing the right one for your application is important for maximum o-ring performance. Another option is increasing the durometer hardness of the compound, which increases the allowable pressure for a defined gap. O-Ring Groove Design.

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. Consultations with our engineering department is highly recommended for critical applications.

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.
