When selecting metals for sealing gases and fluids, several factors such as temperature, pressure, and chemical properties must be considered. The metals listed may provide suitable sealing solutions, but further investigation using the Chemical NACE book is recommended to ensure compatibility with your specific needs.
SECO SEALS manufactures 24-degree, 37-degree, and 45-degree tube fitting gaskets, which may be appropriate for your application.
Disclaimer: This is a general guideline. Verify the suitability of these metals for your specific application by consulting the Chemical Resistance Guide for Metals and Alloys II by Compass Publications and/or a materials expert.
