Before purchasing metal seals, we recommend that you evaluate your working environment by the following questions:

• • What is the operating temperature range?
• • What is the operating pressure range?
• • Is the metal seal going to be subjected to vacuum or corrosive chemicals?
• • What are the expected leakage rates?
