Hi all. I haven't been to America and I don't know American standards. Please help me figure it out. I have a compressor and a Lindsey system. Here is a photo. What kind of hose is needed to connect?

looks to me like a 1/4 to 1/8 npt (national pipe thread) on the compressor side and 1/4 npt on the switch side but im not 100% sure. The tiny white connector is standard medical IV tube connectors.

This is what i use with my lindsay system. one on the compressor side. You match the barb end to the hose size you want to use. Doesnt matter the hose size since the lindsay system uses so little air almost any hose can flow enough. i would just say get one rated for at least 85 psi because you can go up to that with the lindsay hand piece. Looks like 1/4 npt on the compressor and 1/8 npt stepped up to 1/4 npt on the switch side.

so you could get a 1/8 npt to barb fitting that matches the hose you want or get and just remove whats on the switch side. or get a 1/4 npt coupler and a 1/4 npt to barb just like in the photo. The hose just slides onto the barb and is held on with a hose clamp or some other connector like a crimp style.

Quite understandable, thank you.

What you showed on a photo is a Swagelok type connection. It uses a cylindrical threads and two ferrulas under the nut. The nut and ferrulas are missing because once the wedge is installed you can not take it out. Another side is just a standard 1/4" NPT thread. It is up to you what you want to install. There are variety of solutions. You can buy another nut with new ferrulas, another connector with barbed connection, push to connect ( I like these).

Thanks to everyone who contributed to this post. I bought a 1/4 1/8 hose. Hope it fits.
