What is a Y Strainer?

Y Strainers are designed to protect piping system components such as pumps, meters, control valves, steam traps, regulators etc. from damage caused by dirt or debris in flowing liquids or gases. These particles are removed by means of a perforated or wire mesh straining component. This mesh is generally available in either a fine or coarse grade, depending on the size of the particles to be filtered.

The Y Strainer has a removable nut, allowing the wire mesh to be removed, cleaned out and then re-installed into the body. Y Strainers are mostly installed into lines where frequent clean-out of the lines is not required. In lines where there is heavy sediment it is advisable to install a basket strainer.

Y Strainers may be installed in either a vertical or horizontal position, however it is important to ensure the screening element is located on the "down-side" of the strainer body so the entrapped material can properly collect in it.
