Stainless Steel Y-Strainers | Wye Strainers & Replacement Mesh Filters

Protect your valves, pumps, meters, regulators, and other equipment from debris with stainless steel Y-strainers. Also known as Wye strainers, these inline filtration devices remove rust, dirt, scale, and other solid particles before they reach sensitive components, helping improve system reliability and reduce maintenance.

Our stainless steel Y-strainers feature durable 304 stainless steel construction, PTFE seals, and female NPT threaded connections. Available in sizes from 1/2" to 2" NPT, they are suitable for water, air, fuel, steam, and many other compatible media used in residential, commercial, OEM, and industrial applications. They include a reusable 80-mesh (177 micron) stainless steel screen, with optional 50-mesh and 150-mesh replacement screens available.

Why Choose a Y-Strainer?

Even small particles can damage valves and other flow control equipment. Installing a Y-strainer upstream helps prevent debris from entering your system, reducing wear and minimizing downtime.

Benefits include:

• Removes rust, scale, dirt, and debris
• Helps protect solenoid valves, pumps, regulators, and meters
• Durable 304 stainless steel construction
• Reusable stainless steel mesh screen
• PTFE end seal for dependable sealing
• Female NPT threaded connections
• Available replacement mesh filters
• Optional blow-out kit for easier maintenance
• Suitable for commercial, industrial, OEM, and compatible residential applications

Common Applications

Y-strainers are commonly installed in:

• Water systems
• Steam systems
• Compressed air systems
• Fuel systems
• Irrigation systems
• Industrial process equipment
• Food processing equipment
• Water treatment systems
• Pumps
• Solenoid valve installations
• Flow meters
• Pressure regulators
• Heat exchangers
• Manufacturing equipment
• Compatible DIY plumbing projects

Installing a Y-strainer upstream helps keep contaminants away from sensitive downstream equipment.

How Does a Y-Strainer Work?

A Y-strainer is installed directly in a pipeline before the equipment it protects.

As the media flows through the strainer body, it passes through a removable stainless steel mesh screen. Particles larger than the openings in the screen are trapped inside the collection chamber, while clean media continues downstream.

The removable screen can be cleaned and reused, making Y-strainers an economical solution for long-term system protection.

Choosing the Right Y-Strainer

Selecting the correct Y-strainer depends on your piping system and filtration requirements.

Choose the Correct Pipe Size

Our stainless steel Y-strainers are available in:

• 1/2" NPT
• 3/4" NPT
• 1" NPT
• 1-1/4" NPT
• 1-1/2" NPT
• 2" NPT

Choose the size that matches your existing piping system.

Select the Right Mesh Size

Every Y-strainer includes an 80-mesh (177 micron) stainless steel screen.

Replacement screens are also available in:

The correct mesh depends on the equipment you're protecting and the size of contaminants in your system.

Valve Materials

Our Y-strainers feature durable construction for long service life.

This construction provides excellent durability and compatibility with many common media.

Pressure & Temperature

Our stainless steel Y-strainers are rated for:

• Pressure: Up to 800 PSI
• Temperature: -4°F to 356°F (-20°C to 180°C)

Always verify the specifications on the individual product page before installation.

Installation Tips

For horizontal piping, install the Y-strainer with the screen pointing downward so debris collects in the chamber.

Y-strainers can also be installed in vertical piping when the flow direction is downward.

Proper installation makes cleaning easier and helps prevent collected debris from re-entering the pipeline.

Frequently Asked Questions

What is a Y-strainer?

A Y-strainer, also called a Wye strainer, is an inline filtration device that removes debris, rust, dirt, and other solid particles before they reach valves, pumps, meters, and other downstream equipment.

Why should I install a Y-strainer?

Installing a Y-strainer helps protect sensitive equipment from contaminants that can cause clogging, leakage, wear, or premature failure. It is especially beneficial when installed upstream of solenoid valves and pumps.

Can the screen be cleaned?

Yes. The stainless steel mesh screen is reusable and can be removed for cleaning or replaced when needed.

What mesh size comes standard?

Each Y-strainer includes an 80-mesh (177 micron) stainless steel screen. Optional 50-mesh and 150-mesh replacement screens are also available.

Can Y-strainers be installed vertically?

Yes. Y-strainers can be installed in vertical piping when the flow direction is downward.

What is a blow-out kit?

A blow-out kit replaces the standard end cap with a port that allows debris to be flushed from the strainer without removing the screen, reducing maintenance time.

What media are these Y-strainers compatible with?

These stainless steel Y-strainers are suitable for water, air, fuel, steam, and many other compatible media. Always verify compatibility for your specific application before installation.

Can I install a Y-strainer myself?

Many homeowners, plumbers, contractors, and maintenance professionals install Y-strainers in compatible plumbing and piping systems. Always ensure the correct pipe size, pressure rating, and installation orientation before use.

Need Help Choosing the Right Y-Strainer?

Selecting the right Y-strainer depends on your pipe size, media, operating pressure, and filtration requirements. Whether you're protecting a solenoid valve, pump, regulator, or an entire piping system, our team can help you choose the right Y-strainer and replacement mesh for your application.
