VIAIR 92839 Valve for .25 Inch Air Lines

The VIAIR 92839 is a brass inflation valve fitting designed for .25 inch air lines. It suits automotive air suspension systems needing a reliable one-way inflation point. The all-brass construction provides durability in mobile pneumatic applications. It is sold individually for single-point installation.

Check Thread Compatibility and System Voltage

Verify that your air line uses a .25 inch connection matching this fitting. Confirm your compressor system operates on 12 or 24 volt power as typical for VIAIR components. Ensure the mounting location allows access for inflation. The one-way valve design prevents backflow during operation.

Brass Construction Handles Harsh Environments

Natural brass resists corrosion in extreme temperatures from arctic cold to desert heat. The metal body dissipates heat without active cooling or added noise. Power draw depends entirely on the connected compressor unit. No moving parts mean silent operation during inflation cycles.

Questions about this item

What does the VIAIR 92839 valve kit include and what extra parts are needed?

The valve is sold individually with all-brass construction and a natural finish. It fits .25" air line via a compression fitting, so no separate fittings are required for that hose size.

How do I choose between the 12-volt and 24-volt versions of this valve?

This inflation valve is a passive brass fitting with a one-way design; it does not operate on voltage. The 12- and 24-volt figures refer to the VIAIR compressors it connects to, not the valve itself.

What does the one-way brass design mean when the valve is installed in my air ride system?

The one-way mechanism allows air to enter the suspension when inflating and seals automatically to hold pressure. The all-brass body resists corrosion in harsh environments from arctic cold to desert heat.
