Poseidon Sweden Scuba Diving Regulator Set w/ U.S. Divers 4000 PSI Gauge

Condition: Used – Untested / Sold As-Is

Vintage Poseidon Sweden scuba diving regulator setup with hoses, second-stage regulator/mouthpiece, and U.S. Divers pressure gauge.

The first-stage regulator is marked Poseidon Sweden and 2300 PSI. The U.S. Divers pressure gauge reads up to 4000 PSI. Hoses are marked U.S. Divers / pressure tested.

Pre-owned with visible cosmetic wear, scratches, scuffs, discoloration, and age-related wear from previous use and storage. Please review all photos carefully for condition and exactly what is included.

Includes only the regulator assembly, hoses, gauge, and components shown in the photos. No tank or additional accessories included.

CONDITION AND TESTING

We are not divers and do not have a scuba cylinder, pressure-testing equipment or the technical knowledge required to evaluate this equipment. The entire set is untested.

It has not been:

• Connected to a scuba cylinder by us

• Pressurized

• Leak-tested

• Bench-tested

• Internally inspected

• Serviced by us

• Tested for breathing performance

• Verified for safe underwater use

The service history is unknown.

The hoses are vintage. Although they appear clean externally, age-related internal deterioration cannot be ruled out. Replacement may be required.

The pressure gauge is untested and should not be assumed to be operational or accurate based solely upon their visible needle positions.

POSEIDON-SPECIFIC SAFETY NOTICE

Older Poseidon systems may require a particular low-pressure regulator hose or separate overpressure-relief arrangement, depending on the exact first-stage and hose configuration. We have not verified the internal setup, intermediate pressure, overpressure protection, hose specifications or compatibility of every component. The entire assembly must be inspected by a qualified scuba-regulator technician familiar with vintage Poseidon equipment before connection to a pressurized cylinder or any attempt at use for diving.

This is vintage scuba life-support equipment. It must not be used for diving unless the complete assembly has first been inspected, serviced, pressure-tested, and approved by a qualified Poseidon regulator technician. No claim is made that any regulator, hose, gauge, or other component is currently operational, accurate, correctly adjusted, or safe for underwater use.

Please review all photographs carefully. The photographs show the exact equipment included and form part of the description.
