O-ring Selection Guide
Your advantages
Today, the O-Ring is the most widely used seal because of its inexpensive production methods and its ease of use. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.
The perfect O-Ring for each purpose
Our O-Rings are both cost-effective and perform highly in almost every environment. No matter if you need metric or inch, standard or custom-made O-Rings – any size of O-Ring seals is available. We offer EPDM O-rings, FKM O-rings, NBR O-rings, HNBR, as well as our proprietary FFKM, VMQ Silicone O-rings, FVMQ. Special products apart from rubber O-Rings such as O-Rings in PTFE based O-rings and metal O-Rings are also available.
What are O-rings made of and how does this affect their performance?
O-rings are typically made from various materials, including EPDM, which is known for its excellent resistance to heat, aging, and weather conditions. The material composition significantly influences the O-ring's performance, particularly in terms of chemical resistance, temperature tolerance, and compression set. For specific applications, it is crucial to select the appropriate type; for instance, O-rings EPDM provide a good balance of elasticity and durability.
How do I determine the correct size of an O-ring for my application?
To select the correct size of an O-ring, you need to measure both the inner diameter (ID) and the cross-sectional thickness. It's important to account for tolerances and compression in the application. Using a standard sizing chart can also help, and for specific requirements, consider products like O-rings EPDM - 70 Shore A or O-rings EPDM - 80 Shore A to ensure compatibility within your system.
What is the significance of Shore A hardness in O-rings?
The Shore A hardness scale is a measure of a material's hardness, which directly impacts its compression resistance and flexibility. O-rings with different Shore A ratings, such as O-rings EPDM - 70 Shore A - Peroxide Cured or O-rings EPDM - 60 Shore A - Peroxide Cured, will perform differently under pressure and temperature. Selecting the right hardness is essential for ensuring a proper seal and preventing leaks in various applications.
