I was thinking of using a Blichmann quick connector elbow on the inside of my kettle mash tun as the pickup tube. This would attach to a weldless coupling with a nipple. I want an easy way to remove the pickup tube so that I can insert/remove my one piece false bottom. If this won't work, it looks like I would have to use either a compression fitting pickup tube or make one out of copper tubing with a union. Anybody used one of these fittings for that particular reason? Specs are in the link. Thanks.
