When you want a clean, service-friendly way to join pipe to equipment, this flange is a solid choice. This 2 1/2 threaded flange (316 Stainless Steel) is a clean match for 150# raised-face connections. Raised face is the most common sealing face youÕll see for many standard industrial flange connections. 316 stainless is often chosen when corrosion resistance needs to be taken up a notch, especially around chlorides or harsh washdowns. TheyÕre commonly used for maintenance-friendly installs, especially where you may need to break the line loose later. Because they thread onto the pipe, they can speed up certain repairs and modifications. At PLYET Industrial Supply, we stock connection hardware like this because downtime isnÕt an option.
