How to change the exhaust T on Atomic reg?

And the same for the diaphragm/purge covers, too?

Not necessarily. While the size and thread pitch is the same, the purge cover is mated to its retaining ring. So a purge cover has to have a matching retaining ring and these vary between T/Z, B and M models, and in some cases depending upon year manufactured.

With the exception of M1, the 1 series and ti2 purge covers all use the same retaining ring. The 2 series all use the same retaining ring. Similar to 3 series they use same retaining ring as the 2 series. Just with some bling. The M1 has its own specific retaining ring (the std and cave version).

As for the exhausts only M1 exhaust is wider. The newer exhausts are similar, they look bigger cause of the colored trim. But they are about the same size as the original exhausts.

like other said, M1 has the widest tee, then B2/z2, older B1/Ti1/Ti2 has the narrowest tee. They all fit on each other. My experience is M1 tee isn’t they much more better then B2 Tee. I probably won’t bother if function is what I am after. M1 wide tee does look more “aggressive” of you like the look

The thing I notice, M1 also has a longer adjustment knob to accommodate the wider tee. If you just put M1 tee on B2, the knob is a bit harder to grab onto.

As for retaining ring, yes 1 series is different than 2 series. But the same color kit will fit on both. I have B2 purge cover and B1 retaining ring on one self put together AA 2nd stage. Being using it for a long time. I am still alive
