Y Strainers
Bidding a job & need contractor pricing?
We've got you covered!

Professional grade Y strainers are engineered for compact performance and plumbing filtration of liquid media pipelines. They are also known as wye strainers, inline strainers, pipeline strainers, mesh strainers, and filtration strainers. We offer Hayward® PVC Y strainers and CPVC Y strainers as well as Eaton® carbon steel and stainless steel Y strainers that offer industry leading quality, durability and reliability in fluid filtration applications. Y strainers are installed in-line and in loop-flow configurations within plumbing and process media systems. The wye strainer is used to remove undesired materials from piped fluids and provide protection of downstream system components from damage or clogging. They are effective in removing dirt, rust, debris, scale, sediment or other undissolved application particles. These inline strainers are used to keep such media contaminates from reaching potentially sensitive or expensive equipment where it could lower the effectiveness, purity, or lifespan of the total operating system. Common equipment Y strainers are used for include pumps, compressors, condensers, heat exchangers, turbines, spray nozzles, meters, sensors and gauges.
Applications
Y Strainers are suitable for many applications and scenarios. They are often used in water purification systems, wastewater treatment facilities, landfills, chemical production, pharmaceutical research and synthesis, laboratories, universities, medical institutes, data centers, food ingredient handling, beverage processing, aquariums, zoos, water parks, swimming pools and recreation centers, marine environments, industrial services and manufacturing plants. Our industrial Y strainers are suitable and often used for handling many corrosive materials and chemicals that are compatible with PVC or CPVC.
Design and Features
PVC and CPVC plastic inline strainers are engineered to be compact, lightweight and can often be supported by the pipeline installation alone. This allows them to work and be installed where other strainer types often cannot. Y strainers are designed with a 45° angle turn out that holds the filter screen basket and collects unwanted debris that may flow through system plumbing fluid.
The Y strainer is suitable for either horizontal or vertical installation, unlike other strainers that are limited to horizontal or near horizontal installation only. When used vertically, Y strainers must be positioned with the screen located down for the filter basket screen to work correctly. They come with an easy-to-read flow direction indicator for fail-proof installation and easier maintenance. Y strainers feature a hex style screw cap that delivers direct, easy access to the screen chamber. Y strainers have a 2-to-1 (2:1) open area ratio for greater service handling. To clean, the plumbing feed line must be shut down prior unless a blow-out valve has been added.
Materials and Specifications
Available pipeline strainers are made in the USA by ISO 9001 certified manufacturer Hayward Flow Control (YS Series) and Eaton (Model 85). Hayward Y Strainers are made from premium PVC, clear PVC, or CPVC thermoplastic materials. PVDF Y Strainers are available on request, with some options available here. PVC and clear PVC Y Strainers are fabricated from Cell Class 12454 PVC per ASTM D1784 standards and rated up to 140°F (60°C) temperature maximum. CPVC Y strainers are fabricated from Cell Class 23447 CPVC per ASTM D1784 and rated up to 200°F (93°C) temperature maximum. They are pressure rated to 150 PSI at 70°F (10 Bar at 21°C) non-shock.
Eaton Y strainers are made from industrial grade carbon steel or stainless steel metal and pressure rated to 275 PSI to 740 PSI at 100°F (19 to 51 Bar at 38°C) non-shock, depending on the material and flange type.
Screen Options
Plastic Y strainer come with a 1/32" size perforation all plastic basket screen. Screens come standard in all plastic PVC, CPVC, or PP construction material. Carbon steel and stainless steel wye strainer basket screens come standard with stainless steel filter baskets with perforation size options from 1/32" up to 1/2", and basket mesh from 20 to 400 mesh. Various basket screen options are available on request in many different sizes and in alloy materials. Screen size options for plastic screens include perforated screens from 1/32" to 3/16". For metal alloy screens, available metals include stainless steel, Hastelloy®, Monel® or titanium in either perforated screens from 1/32" up to 3/8" or mesh screens from 20 up to 325 mesh. Contact us to request non-standard Y strainer options.
Sizes and Connection Styles
Our commercial Y strainers come in either gray, light gray, or clear (translucent) in color. Thermoplastic strainer sizes range from 1/2" up to 4" in pipe connection diameter. Metal Y strainer sizes range from 3/4" up to 10" in diameter. Gasket and O-ring seals are double O-ring stems. Components are assembled using silicone free lubricants. Strainers come in flanged, threaded, socket and true union type connection styles. PVDF Y strainers can also come in socket fusion type ends for iron pipe size (IPS) schedule 40 / 80 or for SDR 21 / 33 pipe systems.
