Mounts on three 55/60 gallon plastic drums. Used RTV Sealer on one of them and it didn't leak; had a perfect seal. The ones without sealant leaked. I didn't want to over tighten them so as not to break them. Still leaks after giving them an extra 1/2 to a full turn. I don't know the torque specs, but I'm pretty sure they were overtightened. I actually tightened one of them until the rubber gasket was knocked out from under the lock nut, I had to unscrew it. It didn't break the bulkhead, but it's still leaking. Ideal size for PVC pipes. Using a sealant with them gives the best results.
