ANS PRO II regulator adapter replacement for SG CO2 setups

This adapter is the connection piece between your ANS PRO II regulator and the CO2 cylinder, and it is exactly the sort of small part that fails first or gets lost during a refill swap. Keeping a spare on hand means a worn or leaking adapter never forces you to shut down injection for days while you wait. A clean, properly seated connection is what stops the slow gas creep that drains a cylinder between top-ups.

Because CO2 fittings vary by cylinder type, confirm your thread before ordering: locally refilled cylinders and converted fire-extinguisher setups don’t all share the same connection. A fresh adapter with a good seal also reduces the risk of a leak going unnoticed, which is worth checking with soapy water whenever you reconnect after a refill at a local gas supplier.
