Sherwood SR2 Scuba Regulator

The Legacy Continues

Building on the legacy of the SR1, the Sherwood SR2 regulator combines advanced engineering, compact design, and innovative materials to deliver consistent breathing performance at depth.

The SR2 stands out as the only environmentally sealed, internally dry flow-through piston regulator featuring a depth-compensation mechanism. Sherwood’s patented Three Pin Link (3PL) transfers environmental pressure to the piston, helping maintain consistent intermediate pressure and reliable airflow as depth changes.

Designed for divers who value performance, durability, and precision engineering, the SR2 brings together sophisticated first-stage technology and a pneumatically balanced second stage in one compact regulator system.

First Stage Features

• Environmentally Sealed and Internally Dry: Helps protect the first-stage mechanism from external contaminants and water intrusion.

• Five Low-Pressure Ports: Mounted on a 360° swivel for flexible hose routing and improved configuration options.

• Two High-Pressure Ports: Allow connection of a submersible pressure gauge and compatible high-pressure accessories.

• Two-Piece Piston Design: Provides precise balancing and intermediate-pressure control.

• Three Pin Link (3PL): Transfers environmental pressure to the piston to support consistent regulator performance at varying depths.

THREE PIN LINK
In the mid-2000s, Sherwood Scuba created an ingenious depth compensation concept. Using the combination of a flat flexible membrane, a metal plate, and an internal solid mechanical link to transfer external pressure, the SR2 became the first ever flow-through piston regulator that resolved all the issues from its predecessors. With the addition of the 3PL, Sherwood Scuba’s SR2 is unique; it is a flow-through piston system that is both Sealed & Dry, AND it is not messy to work on.

Second Stage Features

• Seat Saving Floating Crown (SSFC): Helps extend valve-seat service life when the regulator is not in use.

• One-Touch Performance Adjustment: Allows convenient adjustment of breathing performance.

• Pneumatically Balanced Second Stage: Designed to provide smooth, consistent breathing performance.

• Super-Flex Hose: Offers enhanced flexibility for comfortable hose routing and diver movement.

• SMART Demand Lever: Reduces loading on the valve seat during storage, helping extend seat life.

• Improved Flexible Purge Cover: Provides convenient purging with a flexible, user-friendly design.

SEAT SAVING FLOATING CROWN
The SSFC is another brilliant engineering solution that prevents premature wear over the LP seat when the sharp edge of a crown pushes in. Sherwood’s exclusive SSFC design does not 
exert constant pressure over the LP seat when the regulator gets depressurized and is not in use. Other regulators on the market use a threadable crown or orifice that seats in one position permanently causing a constant force over the LP seat, sometimes marking it to the point it is no longer effective.

Sherwood SR2: Precision Engineering for Reliable Breathing

With its environmentally sealed piston first stage, depth-compensation technology, versatile port configuration, and pneumatically balanced second stage, the Sherwood SR2 is engineered for divers seeking a high-performance scuba regulator with thoughtful design and advanced functionality.
