Body- PVC. Spool- Derlin. Faceplate- brass. Screws- stainless. ( Most frequent use- Great Lakes = less galvanic issues.) Diaphragm, it’s cover, & exhaust valve salvaged from a Zeagle Octo+ (the integral exhaust valve makes clearing easier). 2nd stage internals from cold water rated Sherwood octo. Mushroom valves & holders from Divematics. Mouthbite- Poseidon. Only one O ring- Viton. Nametag- stuck on in jest.

Been in service 4 ½ years w/ zero problems.
