The same O-ring size can perform very differently depending on the fluid, temperature, pressure, movement, and environment. Explore the material families below and compare the options that best fit your service conditions.
What fluid or media will the O-ring touch? What is the normal operating temperature and what are the short-term peaks? Is the seal static or dynamic?
Will the application see ozone, weather, UV, steam, or cleaning chemicals? Is there any approval requirement such as FDA-grade, NSF, or detectable compounds?
Explore the material options below, including temperature range, best uses, compatibility guidance, and typical applications.
