Purpose and fit
The Viair 92825 is a 1/8 inch female to 1/8 inch male NPT check valve with a 16 mm outer diameter. It allows air flow in one direction while preventing backflow in compressed air systems. Automotive technicians and workshop operators use it to protect compressors and maintain line pressure.
Interface limits
The valve uses standard 1/8 inch NPT threads on both ends, so it fits only ports cut to that taper specification. The 16 mm outer diameter sets the space needed for a wrench during installation. California Proposition 65 notices indicate the product contains chemicals linked to cancer and reproductive harm, which may affect use in regulated environments.
Pre-order checks
Verify that your air system uses 1/8 inch NPT ports and that the 16 mm body clears surrounding fittings or brackets. Confirm the flow direction arrow matches your intended plumbing layout. Ensure local regulations allow components carrying the Proposition 65 warning for your application.

Questions about this item
Is the 92825 the only check-valve size VIAIR offers?
VIAIR produces several check-valve models; the 92825 is the 1/8 inch NPT version with a 16 mm outside diameter.
How does the 1/8 inch NPT thread affect flow in my air system?
The 1/8 inch NPT port limits maximum flow to what that thread size can pass; the valve itself opens at low pressure drop and closes instantly on back-flow.
Will the NPT threads seal directly into my 1/8 inch ports?
Yes, the male and female 1/8 inch NPT threads mate with standard NPT ports; use thread sealant for a leak-free joint.
