Note on Fittings: Two types of fittings are available. A threaded adapter fitting is used primarily with 2" PVC pipe applications. The threads on the bronze fittings are male and can be attached to a threaded female PVC adapter. A no hub fitting is the standard fitting used in the industry. With this fitting a rubber coupling is used to connect the drain to the drainage pipe.
