Mueller Steam Specialty 581 11/2 304 Perforated Screen .033

Perforated Screen 581 304 Stainless

The Mueller Steam Specialty 581 replacement screen is a perforated strainer element made from 304 stainless steel with a .033 inch perforation size. It is designed for use with 1 1/2 inch series strainers in plumbing applications. The screen features a spiral wound graphite filled seal material and meets multiple standards including ASSE, CSA, FM, NSF, UL, ULC, USC, and WQA. This new component serves as a direct replacement for worn or damaged screens.

Verify Strainer Series and Dimensions

Before ordering, confirm that your existing strainer is a 1 1/2 inch series unit compatible with the 581 model designation. Check that the screen length of 5 5/8 inches matches the required dimension for your strainer body. Ensure the perforated strainer type aligns with your filtration needs rather than a mesh alternative. The spiral wound graphite filled seal material should be suitable for the media and temperature in your system.

Sustained Flow Filtration Performance

Under continuous flow conditions, the .033 inch perforations in the 304 stainless steel provide consistent debris capture without rapid clogging. The spiral wound graphite filled seal maintains its integrity during prolonged exposure to system pressures and temperatures. The perforated design allows for steady pressure differentials across the screen during extended operation. The 304 stainless steel construction resists corrosion from water and common plumbing media over long service periods.
