VIAIR 92789 20 ft PTFE Leader Hose
This new VIAIR 92789 leader hose uses stainless-steel braided PTFE construction with an integrated check valve. It connects an air compressor to tools or tanks in automotive and workshop settings.

20 ft length with check valve decides fit
The twenty-foot length and built-in check valve determine whether this hose matches your compressor layout and prevents back-flow. Verify the required reach and valve requirement before ordering. No other dimensions or pressure ratings are provided in the data.

Questions about this item
What compressor fitting does the 1/4-inch end of the 92789 leader hose need to thread onto?
The 1/4-inch NPT end of the VIAIR 92789 hose threads directly onto a compressor outlet or regulator port with matching 1/4-inch NPT threads.
Will the stainless-steel braided PTFE hose handle the same pressure as my older rubber leader hose?
The PTFE core and stainless-steel braid are rated for high-pressure air service and typically exceed the burst rating of standard rubber leader hoses.
How can I verify the built-in check valve is sealing correctly after installation?
Pressurise the system, then shut off the compressor; the hose should hold pressure without bleeding back, confirming the check valve is functioning.
