The Mares XR 25X 1st Stage is a 1st stage with single sided ports for sidemount stages with optimum hose routing. Ports on one side of the 1st stage allow you to route all of your hoses downwards for a DIR setup. Extremely reliable the balanced diaphragm design is machined from a single piece of nickle-plated marine brass with an ACT Valve for enhanced lifespan.
The port configuration also works perfectly with deco stages so all the hoses route straight down the cylinder to reduce snagging or damaging hoses whilst leaving the valves clutter free for access.
