The Oceanic SP5 1st Stage Regulator is a first-stage-only piston regulator built around a non-balanced flow-by piston fail-safe design, offered in both DIN and Yoke connection types, with marine-grade chromed brass construction for saltwater service. It is a simple, dependable air source for divers and dive operations that want straightforward performance and easy maintenance.
Who it is for
The SP5 suits recreational divers who want an uncomplicated, serviceable first stage, and it is widely used in rental fleets and resort operations where regulators are assembled, inspected and rebuilt on a regular cycle. Because it is sold as a first stage only, it is also a practical choice if you are building a regulator set around second stages you already own, or replacing the first stage in an existing configuration. The DIN and Yoke options let a shop or traveling diver match the tank valves in use locally.
Key details
- Design: non-balanced flow-by piston, fail-safe
- Material: marine-grade chromed brass
- Standards: exceeds US Navy Class A and European CE standards
- Configuration: first stage only, no second stage included
- Connection: choose DIN (SKU 40.7531) or Yoke (SKU 40.7530)
Compatibility and sizing
Choose the Yoke (A-clamp) version for the clamp-style tank valves common across much of the recreational world, or the DIN version for valves that accept a threaded regulator, which is standard across much of Europe and in technical diving. Since this is a first stage only, confirm that your second stages, hoses and gauges use fittings that match the ports on this first stage before you order.
