About this 3D model
This kit is composed of a nut to secure your 3/4in threaded male through any surface you have previously drilled, and also a filter to get clean water. You will need to put some teflon tape plus maybe some silicon sealant behind the nut to achieve good watertightness. After putting in place the nut, you can press fit the filter on it. It can still be removed easily to be cleaned without altering the sealing.
