Heater union components

Here you will find all the parts you need to replace your 1.5-inch and 2-inch heater unions, and other less standard sizes.

A complete heater union assembly is composed of a two-part split nut held together with two screws (so you can change the ring without having to cut and re-glue the pipe), a gasket and a union tailpiece to which you can glue the corresponding pipe.
