Here is the description from the manufacturer:
First Stage:
With the bulletproof design of the Hollis HP5 non-balanced flow-by piston first stage the H-O2 Tech Regulator is certified for up to 100% oxygen service thanks to highly specialized component materials and manufacturing processes. Cleaned and assembled in a clean room environment with specially designed materials, halocarbon based lubricants and color-coded for easy identification. The H-O2 First Stage Regulator comes with a 300 BAR/4500 PSI DIN connection. The DIN hand-wheel connector comes in oxygen green for easy identification for oxygen use only. The H-O2 is manufactured from durable and corrosion resistant marine grade chrome plated brass, has 4 LP 3/8" threaded ports and 1 HP 7/16" threaded port.
The flow-by piston design is the only true fail-safe first stage design on the market. The piston will automatically move downstream from the high-pressure air coming from the Scuba cylinder if there is an unexpected malfunction of the high-pressure seat. This feature guarantees a constant gas-flow to the second-stage regulator. The regulator first stage weighs 8.3 oz. (235.3 g).
