Non-Alloy Simplex Strainers


  • PVC and CPVC
  • GFPP
  • Platinum GFPP
  • Eastar (clear) copolyester
  • PTFE and PVDF
We offer many non-alloy simplex strainers, most are injection molded and readily available for quick shipment.  There are some fluids and environments for which plastic is a superior material for a simplex strainer.  Our non-alloy simplex strainers eliminate all metal components and therefore eliminate corrosion issues without having to rely on coatings or exotic alloys.


With exception of the PVDF and PTFE simplex strainers, we utilize true union end connections.  The connection types are threaded, socket or 150# RF ANSI flanged.  The true union connection to the strainer body enables removal of the strainer from the pipeline with no tools and it also makes installation easier for alignment of flange holes and threading both the inlet and outlet.


The physical design includes ergonomic chamber cover handles for removal without using tools.  The mounting feet are part of the molding complementing the flat bottom design for a secure installation.  Most models have two outlet ports, enabling you to install in-line (nozzles are directly opposite from each other) or "loop" (nozzles are on same side).  Sometimes the loop configuration is beneficial to minimize the installation footprint. 


The standard strainer baskets are made from either perforated PVC or CPVC although we can supply alloy baskets with perforations or mesh linings in 316SS, Monel, Hastelloy and Titanium.


 Our non-alloy simplex strainers are really wonderful although there are some limitations: due to differential thermal expansion rates between metal and plastic, transmittal of pipe vibration, and pipe loading forces DIRECT INSTALLATION OF METAL PIPE INTO PLASTIC CONNECTIONS IS NOT RECOMMENDED. Wherever installation of plastic strainers into metal piping systems is desired, it is recommended that at least 10 pipe diameter in length of plastic pipe be installed upstream and downstream of the plastic strainer to compensate for the factors mentioned above.


To properly select a simplex strainer, select the desired material of construction from the navigation menu and a listing of all available sizes, along with a link to their outline drawing and discounted pricing will be provided in table format.  Use the embedded differential pressure calculator to determine the most appropriate size for your application.


Even though we try to provide as much information as possible to help you decide which model is best for your application by providing links to outline drawings and an embedded differential pressure calculator, it is always a great idea to contact us using our application oriented inquiry form.  We usually respond within 24 hours.
