We stock a complete range of threaded Y-strainers in sizes up to 2". Matco-Norca models have a lead-free cast bronze body and are 300 psi WOG / 150 psi SWP rated with factory installed plug. Wright Valves models are 200 psi WOG rated and have a lead-free brass body. 18 mesh stainless steel screen standard on all models. Threaded ends comply with ANSI B2.1
Y-strainer or “wye” strainer is device intended for removal and retention of debris, sediments and other small solids present in plumbing, heating or cooling systems by means of a stainless mesh screen. The strainer comes with an angle outlet with a tapping at the bottom (forming a letter "Y" and hence the name), which accumulates the debris and can be cleaned (purged) by removing a factory installed plug.
Y-strainers help to protect valuable system components, such as boilers, heaters, heat exchangers and pumps from failure and malfunction caused by build-up of sediments. Installing a y-strainer will allow to reduce frequency and costs of equipment maintenance.
Frequently Asked Questions
Q: Which side is an inlet and which is an outlet?
A: Y-strainer has an arrow on its’ body pointing the direction of the flow. Also, the sediment collector branches off in the same direction as the flow.
Q: What's the best way to install a Y-strainer - vertically or horizontally?
A: It can be installed in either position as long as the tapping at the bottom of the sediment collector is pointing down. This way, the solids can be properly entrapped and easily purged.
Q: Which option is better - Bronze or Cast Iron?
A: Bronze is, without doubt, a more reliable material in all aspects. Due to the nature of the y-strainer, it’s supposed to filter the sediments, not produce them. Cast iron strainers are subject to corrosion and with time, will likely produce flakes of iron oxide which will be carried by the flow to the very equipment that requires protection against them.

Why don't we show the price?
While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
