Viair 92824 Check Valve 1/8 NPT

This Viair 92824 check valve connects 1/8 inch male NPT threads to 1/8 inch female NPT threads with a 16 mm outer diameter. It permits airflow in one direction while preventing reverse flow in compressed air systems. The component is supplied new and intended for pneumatic line installations.

Suits 1/8 NPT pneumatic lines needing backflow

Installers working with 1/8 inch NPT fittings can use this valve to protect compressors and downstream equipment from reverse pressure. Systems requiring a different thread size, a larger flow capacity, or a non-NPT thread standard will need an alternative component.

1/8 inch male to female NPT thread specification

The defining specification is the 1/8 inch male NPT inlet and 1/8 inch female NPT outlet. Matching these exact thread forms and the 16 mm outer diameter to the existing plumbing determines whether this valve fits the application.

Questions about this item

How does the 1/8" NPT check valve affect airflow direction in a real air system?

The valve allows air to flow only from the male 1/8" NPT side toward the female 1/8" NPT side, preventing backflow when the compressor unloads.

What does the NPT thread standard cap in practice for this 1/8" fitting?

NPT threads seal by taper interference, so the 1/8" connection relies on thread engagement and sealant rather than a separate gasket.

What clearance does the 16 mm outer diameter need to fit or mount?

The 16 mm OD requires a straight 16 mm bore or wrench flat, plus enough length for the NPT thread engagement on both ends.
