1-1/2" FNPT 304L Stainless Steel Union

The P-WAT-3461 (Merit Brass Part Number: K487-24) is a three-piece fitting that connects two pipes while allowing for future disconnection without disturbing the rest of the piping. Its stainless steel construction ensures high durability and superior resistance to rust and corrosion, making it ideal for the demanding fluid environments found in water treatment centers.
