How to Determine the Revision number of your Equilibar regulator

1. Look at the part number listed on the regulator’s label
2. In general, the number right before the first “dash” is the revision number
3. For all models EXCEPT the GS Series, follow this table:
   • Box 1 – model name (LF, H6P, FDO, etc)
   • Box 2 – inlet/outlet port size
   • Box 3 – body material
     
   • Box 4 – inlet/outlet port thread type
   • Box 5 – body “trim”
   • Box 6 – Revision number (may be a single number or a number/letter combination)
4. To find the revision number of the GS model, follow the table below. Boxes 1-4 serve the same purpose as above.
   • Box 5 - has the body “trim” and the revision number. The trim is a letter. Revision number may be a single number or a number/letter combination.
