Hollis Brass Pressure Gauge
The Hollis brass SPG combines a luminous dial with a tempered-glass lens and chrome-plated housing. Its separate-gauge format suits divers who want a simple pressure instrument that can be positioned on a hose to suit their rig.
Features and benefits
- Low-light readability. The luminous display helps you identify the reading after appropriate light exposure.
- Protected viewing surface. The scratch-resistant tempered glass window protects the dial while keeping the reading visible.
- Metal gauge housing. The brass-based housing provides a robust body for a separate pressure instrument.
Setup and compatibility
Match the gauge, high-pressure hose and fittings to your regulator setup. A dial’s maximum marking is separate from the equipment’s permitted working pressure. Gas compatibility: Factory oxygen-clean; maintain oxygen cleanliness throughout the connected system.
What’s included
Air spool and Viton O-rings.
