Elements Of A Brass Filter

The design of a brass Y filter is pretty simple to understand. It maintains the Y shape according to its name. Anyways, the components of a brass Y filter are:

The Y filter has three ends: the inlet, the outlet, and the filter leg. 

The filter leg is attached to the valve body (inlet and outlet) at a 60-degree angle. This is the main part of this filter. This section has a cap at its top to cover the filter opening. The cap looks like a hexagonal nut from above, but it has threads at the bottom. In addition, right underneath the cap, there is a rubber gasket to make the joint at least watertight. 

After removing the cap, you will see a cylinder-shaped mesh filter filter (also known as Screen) inside there. This mesh filter filter is directly connected to the inlet with the same angle of 60 degrees. Moreover, you can easily remove and put it there by means of removing the cap.

Lastly, the two ports are remaining. You will notice an arrow on the filter body. It indicates the media flow direction. So, the arrow pointed port is the outlet and the opposite port is the inlet.
