Pre Rinse connections come in two forms, BSP (British Standard Pipe) thread and NPS (National Pipe Straight) threads. NPS is more common in America and, as almost all Pre Rinse units are based on American models, almost all manufacturers stick with this thread. Some manufacturers even produce both forms.
We stock only NPS threaded pre rinse spare parts.
Encore, T&S, and Aquajet, all use NPS connections and our parts will be compatible.
In the unlikely even that out part is not compatible with your pre rinse unit you can return it for a refund as long as the part is in a resalable condition with no marks. Never try to force one type of thread onto another.
