Helpful FAQs

What is a cross section?
A cross section is what you'd get if you took a finished part, cut it in half, and looked at the ends. The cross section can tell you a lot about how the seal functions. For example, the cross section of a u-cup can give you a better understanding of how the lips function while the system is pressurized. Cross sections are often used to gather information on why a seal may have failed and to assess the locations where wear may be occurring.
Do you stock metric seals?
Yes, R.E. Purvis & Associates, Inc. stocks metric o-rings and seals in a variety of configurations and compounds.
What is a dynamic application?
A dynamic application is used to describe situations where the seal is located between two components that are moving relative to each other. An example of a dynamic application would be a piston seal or rotary shaft seal.
How do I determine what compound to use to best service my application needs?
The material that is selected for a specific application depends on several factors. The fluid it will come in contact with, the temperature it will deal with, the pressure the part is exposed to, the length of time the part must last, and how much the customer is wiling to pay are all contributing factors. Your best solution to finding the right compound for your application is to contact us. The trained staff of R.E. Purvis & Associates, Inc. will be able to isolate the compound that will best suit your application's needs.
