What this hose is
The Velvac 142518 is a stainless steel air compressor hose built as a coupled assembly with brass FNPSM fittings on both ends. It is designed for compressed-air systems that require a flexible, high-temperature line between the compressor and the tool or distribution point.
The specification that decides fit
Each end uses a 7/8 in FNPSM brass fitting, so the hose only connects to ports with the matching straight mechanical thread. The 1/2 in bore and 18 in overall length fix the flow path and reach, while the PTFE tube and stainless cover handle a range from -100 to 450 degrees F under SAE J517.
Who should choose it and who should not
Shops needing a short, heat-resistant jumper with standard brass ends will find it suitable. Buyers who need a longer run, a different thread type, or a non-metallic cover should look at other options.

Questions about this item
What does the 18 in length mean once the hose is installed on a compressor?
The hose provides an 18 in reach between the compressor outlet and the tool connection, giving a fixed working distance of 18 in.
How does the SAE J517 standard affect the pressure rating and fitting compatibility of this hose?
SAE J517 defines the construction and test requirements for the hose, ensuring the PTFE tube and brass FNPSM fittings meet the standard's pressure and dimensional criteria.
What clearance and thread size are needed to mount the 7/8 in FNPSM brass fittings on this hose?
Each end has a 7/8 in FNPSM brass fitting that threads onto a matching MNPSM port; allow enough space for the 5/8 in outside diameter hose and the fitting nut to engage fully.
