My regulator has an ideal needle valve and until now, a drop checker mounted to that. It worked great for years, but in the last 6 months I've had the plastic cylinder on that drop checker break twice.. it appears thats the only one available for that configuration too! So I'm thinking of switching to attaching the hose directly to the regulator and doing an inline bubble counter. I'm having a lot of trouble finding the brass part necessary to make this happen. Is there a standard part somewhere I can order for this? I feel like I'm spinning my wheels on this so any direction would be great. TIA!
