Yong Heng compressor but what hose

Not an expert on fittings but there should be a DIN300 to foster adapter available. Might try PA or airtanksforsale-Joe Brancato. I purchased my SCBA adapter from JB to fill my tank at the local fire station and my tank has a male adapter screwing into the female tank with a foster fitting on the other end. Others with more specific info will probably post.
