Poseidon Cyklon HP Port Adapter

On older Poseidon Cyklon 1st stage SCUBA regulators, the standard thread size of all ports were 1/8. Today, all LP ports are 3/8 and all HP ports are 7/16 sized.

If you have an older style 1st stage, this adapter can be used to attach a standard High Pressure Hose.
