We use extensively metric tubing for pneumatic aplications. The DIN pipe fittings are very compatible with NPT threads so one can use them directly into a female NPT thread but is officially not recommended. The tubing becomes an even metric size (4,6, .. mm). The supplier I use for pneumatics is FESTO. I don't know about copper or SS fittings but I will find out and let you know. -----Original Message----- From: Steve Johnson [mailto:[EMAIL PROTECTED]] Sent: Friday, 03 November, 2000 10:19 To: U.S. Metric Association Subject: [USMA:8976] Tube fittings We currently use significant numbers of NPT compression fittings in an assembly. What options are available in Metric. Is the ISO fitting becoming standard worldwide or is there significant variation from country to country? Metric tubing appears to be available. What is the most common Metric Fitting? Where can I source them? _________________________ Steven RS Johnson Senior Manufacturing Engineer IDATECH Phone: (541) 383-3390 mailto:[EMAIL PROTECTED]
