first stage

I know the DIN vs Yoke conversation is something that has already been beat to death on this forum. I’m not looking to start another conversation on which is better. I am however interested in gathering some empirical data regarding how far the regulator sticks out from the tank, and thus how...

Hi all, I just received back my Apeks XTX200 regulator after sending it for servicing for the first time. I notice that the colour on the faceplate of my first stage (Apeks FSR) was stripped off. The technician said that this is normal due to the age of the regulator combined with the cleaning...

Hey guys, These were in a parts drawer at my LDS. I initially thought they were for a Mistral or Aqua Master, but upon inspection it appears they are different. There is one Aqua Master seat in the mix, the third seat from the left. Any idea what regulators these seats belong to? Thanks, Erik

It may take a while to collect enough data on this given the generally low failure rate, however, it would be great to have some insight into when people here experience regulator failure. We will see the regulator set as a whole, that is, not differentiate between first or second stage...

Hello, I just got an European first stage (300 bar) that I want to use in the US (230 bar). Is there any adapter in the market to convert a first stage 300 bar to 230 bar? Thanks DJ
