Using Viair 88P to Blow Out Water Lines

dcolden · August 2023

For those using a Viair 88P or other compressor with a screw on air chuck, what do you use to adapt the chuck to a regular air hose?

Was looking at these adapters, but not sure of the valve stem is needed.

I want to make sure I get all the bits and pieces I need to hook up to the city water connection. Already have the 1/4" Quick disconnect to GHT adapter and an air pressure regulator. This is the last piece of the puzzle.

Links appreciated.

This is what I use to blow out my lines. I turn the pressure way down to 20 or so pounds. The female to female garden hose fitting is for blowing out the plumbing at

my cabin. There are cheaper ways to do this, but I had fun building these up.

@dcolden - on our 2017 CSS we use a Viair with the Schrader valve coupled with this adapter to plug into the city water outlet:

I bought a blowout adapter. I am trying to figure out the connection from the 1/4" QD fitting to the Viair hose. I don't think that the air chuck is removable on the Viair 88P. I think it is permanently crimped on, but can't tell from photos or literature.

Here is a pic of my blowout adapter. I bought it before I realized that my air compressor is not an oil-free design.

I hadn't found that adapter in my search. Thanks.
