This 1/2 threaded flange is 304 Stainless Steel with a raised face face in 150#. They’re commonly used for maintenance-friendly installs, especially where you may need to break the line loose later.
The job of this threaded flange is straightforward: it gives you a standard bolt-up point so your line can connect to other flanged components.
304 stainless is a reliable all-around choice for many industrial environments where corrosion resistance matters. The raised-face sealing surface is designed to mate well with common gasket styles used on stainless systems.
From quick repairs to planned upgrades, PLYET Industrial Supply ships the flanges you need without the runaround.
