Gentec 197M Medical Gas Regulator

The Gentec 197M is a high-quality brass medical gas regulator with a matte chrome body, adjustable yoke system, and self-sealing outlet — designed for clinical environments where flowmeters are connected and disconnected frequently. The self-sealing outlet ensures no oxygen flows until the flowmeter is properly connected, reducing waste and preventing accidental discharge into the room.

Key Features

• High-quality brass with matte chrome body — durable, professional finish.
• Adjustable yoke system — fits a range of cylinder valve types.
• Easy-to-read pressure gauge.
• Self-sealing outlet — no oxygen flows until flowmeter is connected.

Specifications

• Body: High-quality brass with matte chrome
• Yoke: Adjustable
• Outlet: Self-sealing (oxygen flow gated by flowmeter connection)
• Gauge: Pressure indication

Why the self-sealing outlet matters

In clinical environments where one regulator may serve multiple flowmeters across rotating shifts and patients, a self-sealing outlet prevents oxygen waste between flowmeter changeovers. It also reduces the risk of accidental high-flow oxygen discharge into the patient room — an oxygen-enrichment fire hazard that conventional regulators don't protect against.

Frequently Asked Questions

197M vs 286 — which?
197M for clinical wards with frequent flowmeter changeovers (the self-sealing outlet adds value here). 286 for ambulance and field use where the piston design and sintered filter offer more rugged performance.

What does "adjustable yoke" mean?
The yoke is the connection between the regulator and the cylinder valve. An adjustable yoke can fit a wider range of cylinder valve geometries — useful when your supply cylinders may come from multiple sources.

Is this oxygen-service certified?
Yes — designed and certified for medical oxygen use. As with any oxygen equipment, never apply oils, lubricants, or solvents to the regulator.
