1.5 inch NPT end fitting stainless steel filter are made from V shaped profile wire, which is spirally wound around a cage of longitudinal support rods. Each intersecting point of these wires is fusion welded, with an unique welding process. This spacing gives passage for water to enter. The entire process is completed on fully computerized machines. The pitch of winding gives different spacing between two adjacent turns of wire.
NPT cap is the end fitting of the filter. NPT is standard threaded screw. Many filtration machine match NPT end fittings. NPT cap can be made into 1", 1"1/4, 1"1/2, 2" and more sizes according to clients' requests.
The main part of the 1.5 inch NPT end fitting stainless steel filter is the filtering part. It is made of stainless steel wedge wire. Because it is designed by Johnson. So it is also called Johnson screen. Until now. it has many different names. Wedge wire screen , slot tube, filter screen ,wedge wire mesh, wedge wire filters, johnson screens, micro screen, pipe screen, filtration element.

Specification of 1.5 inch NPT end fitting stainless steel filter
Material for Micro filter mesh
We use normally 304 and 316L S.S Material which were all imported from world famous supplier. Complete specifications for material to adapt to customer demand.
Construction for 1.5 inch NPT end fitting stainless steel filter
1. We use wedge-shaped profile wire in order to make the slot v-shaped.It can stop the impurities very well.
2. The wedge wire was welded on the support wire well-proportioned and have perfect roundness. Ensure the screen have bigger filter area and non obstructive, avoid the high concentration of impurities.
3. After work for a period of time, the filter can be back flush.It can use for many times.
