Atomic First Stage Environmental Seal

Atomic First Stage Environmental Seal Kit   This is the environmental seal for Atomic First stages.  If you have a non sealed version replace it with this one.    You will still need to fill the piston assembly with Tribolube this is required and very easy to do.      Quick Tip on filling the balancing chamber:   The easiest way to fill the chamber is during rebuild. All you do is place the spring on the piston and fill the entire center section full of Tribolube.  Then fill the spaces between the spring. Assemble the reg and then fill any reamaining space through the balancing chamber ports. Then pop the cap on. You might find some squirt out once the reg is pressurized this is common and considered normal.
