I bought some at a pool / hot tub dealer on route 44 in Coventry. Is says right on it to use PVC solvent and cement (available anywhere). I believe that most pool places stock it in 1 1/2" and 2". If you're going to bend it a lot and glue it to regular schedule 40 PVC it is better to glue the fitting straight on the flex tubing first, then bend it and glue to the other pipe. Otherwise you don't get a good glue joint if the flex tubing comes out of the fitting at an angle.
