Question about Plast-O-Matic miniature air-operated PTFE diaphragm valves (X1365-M vs X1365-AGM)

Hi all,

I’m currently working on a small process setup that uses Plast-O-Matic miniature air-operated PTFE diaphragm valves, and I came across two models: X1365-M and X1365-AGM.

I’m trying to figure out:

• What’s the main difference between these two models?
• Are they interchangeable or designed for different service conditions?

If anyone has experience with these or has worked with similar PTFE air-operated valves, I’d really appreciate your input.

Thanks in advance!
