This is the 30 foot extension Air hose for the VIAIR air compressors. This works with the VIAIR model 300, 400, and 450. The hose is a female to male and can handle up to 200 PSI. This is a great add on to the VIAIR 300 model that only comes with 30 feet of air hose. You can also have this hose on stand by if you have the 400 or 450 model, just in case you get in a situation that you need more hose length.
This hose is internally braided and comes with a storage bag. THis hose is as high quality as the VIAIR air compressors are.
