This fitting is 4 1/2" long and has a 2" diameter. It is made of standard weight Hi-impact PVC II with full 3/4" hub indexing alignment marks. The manufacturer suggests avoiding PVC SCH40 fittings. They are thin and leave a 'step' where the pipe connects. Toothpicks or pins could get stuck creating clogs. Also make sure fittings have a 3/4" cuff, not 1/2", to provide strength at joints.
