Frequently Asked Questions (FAQs)
#
What materials can custom molded O-rings be made from?
Custom molded O-rings can be made from a variety of materials, including Nitrile (Buna-N), Viton® (FKM), EPDM, Silicone, and specialized elastomers like Kalrez® (FFKM) and Santoprene TPV. Each material is chosen based on the specific application requirements such as temperature, chemical exposure, and pressure.
#
Why might I need backup O-rings for my application?
You might need backup O-rings to protect your primary O-ring seal from high pressure and temperature. Backup O-rings limit the extrusion gap, preventing the primary O-ring from being squeezed out of its groove, thus enhancing the seal’s durability and performance.
#
How do I determine the correct size for my custom O-ring?
To determine the correct size, consider the diameter and width of the mating surface’s groove, as well as the material’s flexibility. Ensure the O-ring’s diameter is slightly smaller than the installation groove to achieve a secure seal.
#
What are the differences between compression molded and continuously molded O-rings?
Compression molded O-rings are ideal for high volumes of small to medium-sized O-rings and require tooling. Continuously molded O-rings are better for large, non-standard sizes and smaller volumes, with no tooling cost involved. Both methods are suitable for static and dynamic applications.
#
Can custom O-rings be coated for additional protection?
Yes, custom O-rings can be coated to increase their chemical, weather, and abrasion resistance. Coatings can also reduce friction and prevent the O-ring from sticking or breaking. Various colors and types of coatings are available to enhance durability and productivity.
