Gas Saver for Acetylene and Oxygen

The Miller-Smith Equipment WDW101 shuts off gas flow when the torch is not in use. It suits welders who want to reduce waste during intermittent work. The unit fits standard acetylene and oxygen supply lines.

CGA-023 Connections with 9/16 Inch UNF Threads

Both inlet and outlet use a 9/16 In. -18 UNF connection matched to CGA-023. This threading lets the saver join existing hose fittings without adapters. The connection type is identical on both sides for straightforward inline installation.

Brass Body Built for Workshop Conditions

The brass construction resists corrosion from gas exposure and daily handling. Internal valves close automatically when pressure drops at the torch. The compact form sits inline without adding bulk to the hose run.

Questions about this item

Does the WDW101 gas saver need periodic replacement of internal seals or O-rings?

The gas saver uses standard 9/16 in.-18 UNF connections; seals at those fittings should be inspected and replaced during routine torch maintenance.

What is the first limit reached when the gas saver runs continuously on a heavy cutting job?

The CGA-023 rating defines the maximum flow capacity; exceeding that flow will be the first limitation encountered.

Does the WDW101 generate noticeable heat or noise during all-day operation?

As a passive mechanical valve with no moving actuators, it produces no operational noise and negligible heat.
