you should be able to use a beer nut and tailpiece with that. the threading and size should be the same as that for connecting tubing to shanks.
you will also need a neoprene washer and the tailpiece that fits your tubing
i would recommend the 1/4'' tailpieces, as the 3/16'' tubing will fit very snugly on there, and even more securely with a clamp.
hope this helps.
