OCEANIC SPX REGULATOR 1ST STAGE ONLY YOKE OR DIN

The Oceanic SPX Regulator First Stage Only (SKU: 40-3781 / 40-3780) is a lightweight, reliable, high-performing piston first stage regulator designed for entry-level to advanced recreational divers.

Known for its compact architecture, low maintenance requirements, and effortless breathing performance, the SPX first stage provides consistent intermediate pressure and smooth air delivery across a wide range of dive depths and operating conditions.

Its pneumatically balanced second stage dramatically reduces resistance, resulting in truly effortless breathing.

A great value regulator with no compromises on capability.

The lightweight and compact Alpha 10 was designed to be easy to use, easy to service, and like all our gear, it was built to last.

It comes with a lifetime warranty and free parts for life.

Oceanic introduces its new sPX Regulator. Simple, dependable, and economical. What else would you expect from a design as refined and perfected as the Alpha? Effortless breathing in a compact design that is extremely tough yet easy to maintain and service. The Oceanic Alpha 10 + sPX Yoke First Stage Regulator is a non-balanced flow-by piston-designed regulator. This simple yet fail-safe design will deliver air even if there is a first stage failure. Made of triple-chromed marine-grade brass for durability and long life, the first stage has 4 LP ports and 2 HP ports with 3/8" and 7/16" threads. The LP ports are angled for optimum hose routing. The regulator can be used with air or nitrox mixtures up to 40 percent right out of the box.

Unbalanced Piston Mechanism: Designed with a simple, robust unbalanced piston design that provides exceptional reliability, long service intervals, and consistent performance in warm and temperate waters.

Compact & Lightweight Architecture: Streamlined, low-profile body reduces overall gear weight and drag underwater, making it an ideal choice for travel divers and lightweight rig configurations.

Chrome-Plated Marine Brass: Precision-machined from high-tensile, marine-grade forged brass with a heavy-duty chrome finish to protect against saltwater corrosion, impact, and wear.

Optimized Port Layout: Strategic placement of high-pressure and low-pressure ports ensures clean, angled hose routing for primary regulators, octopuses, BCD inflators, and console/transmitter units.

Nitrox Compatible: Factory prepped and safe for use with Enriched Air Nitrox (EANx) mixtures up to 40% O₂ directly out of the box without requiring additional oxygen cleaning.

Dual Connection Options: Available in standard Yoke (SKU: 40-3780, rated to 3,000 PSI / 232 BAR) or DIN configuration (SKU: 40-3781, rated to 4,350 PSI / 300 BAR).
