Aerox Retrofit Assembly - PB1 (Puritan 750) Fitting Overview:

Aerox Retrofit Assembly with Needle Valve, Flowmeter, and PB1 (Puritan 750) Fitting

This Aerox retrofit assembly combines a needle valve and flowmeter in one compact setup for convenient oxygen flow adjustment in flight. It includes a PB1 fitting, also known as a Puritan 750 fitting, for compatibility with systems that use that connection style.

Because the needle valve is integrated with the flowmeter, pilots can set and monitor oxygen flow from a single assembly instead of working with separate components. That makes this a practical option for replacing worn parts or updating an existing oxygen setup.

• Retrofit assembly for aviation oxygen systems
• Includes integrated needle valve and flowmeter
• Supplied with PB1 (Puritan 750) fitting
• Allows convenient in-flight oxygen flow adjustment
• Combines flow setting and flow indication in one assembly

For pilots shopping for oxygen system parts, the key detail is the fitting type. This assembly is intended for setups that use the PB1 / Puritan 750 connection, so matching your existing oxygen equipment is important before ordering.  Also available with other fittings.
