O ring design guide metric

Metric O-Rings are a type of mechanical gasket used for sealing applications. They are a specific variation of O-Rings, o ring design guide metric, 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 ISOmaking them suitable for applications that follow metric specifications.

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.

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. 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. A dovetail O-ring groove is a type of O-ring groove design that incorporates a dovetail-shaped cross-section.

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.

Since , our solutions have delivered reliable, long-lasting success for customers worldwide. The second table is for static industrial radial applications. 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. This is the gap used when designing for extrusion. Request a Quote. Try our new Online O-ring Store. Website by Highland Creative. Search Close this search box. Speak with a Product Expert. Levels of Inner Diameter stretch for O-Rings are application dependent.

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

In the sealing design, unless the bore and piston or rod are ensured to remain concentric by bearings, it must be assumed that all the gap possible can shift to one side. Share on Twitter. Download the AS Guide. This is the most straightforward of groove designs. Request Quote. 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. The issue is that at higher pressures from one direction, the o-ring can be forced into the small gap and get damaged. Static Cylinder Grooves.
