These Ridgid Gold Dies 1/2″ to 3/4″ are high speed for stainless steel pipe.
These Dies are a universal fit for most Die Heads.
Die Heads the Gold Dies fit are 811A, 815A,816, 817,856,911,913, and 504A.
If you can manage to have each set of Dies in it’s own head, this would save a lot of time on site.
