Is the thread on the Poseidon Extreme the same as on other regulators?
The thread is interchangable with the Jetstream, but this is for the LP hose. I can't comment on other Poseidon products. I have both versions, and have interchanged the Extreme with the Jetstream and vice-versa. However, the LP hoses are specifically sized for their own products, and are not interchangeable with most other regulators that I am familar with. Having said that, I have enjoyed both products as they are simple, but robust...)
OC only!
Hope this helps!
