We have designed this kit for those who wish to connect their water filter systems to taps with 3/4" thread which are commonly found in laundrys, bathrooms etc.

This is ideal for people who don't have a lot of room in their kitchen or would just like to have other options.

This kit is only suitable for water filters that run off 3/8" tubing.

Getting the right thread sizes

The tables below may help you identify the correct fittings for your application.

Please note that Nominal Size (1/2" JIC or 1/2" NPTF, for example) frequently refers to the Inner Diameter of the pipe or the Overall Diameter of the tubing for which that fitting is intended. This should not be confused with the dimension of the thread, which is nearly always larger than nominal tube or pipe size. 

1/4" Ports approx 12.5mm across the thread 
1/2" Ports approx 20mm across the threadGT
3/4" Ports approx 25mm across the thread
1" Ports approx 32mm across the thread
