Industrial 507369 Stainless Steel 3 Inch NPT Pipe Union

Description:

The 507369 Union is a 3-inch female NPT threaded pipe union manufactured from ASTM A182 F304 stainless steel. Rated for Class 150 / 1000#, this three-piece fitting is designed to connect and disconnect piping systems quickly while maintaining a secure, leak-resistant seal. It is commonly used in chemical processing, oil and gas, food processing, water treatment, and industrial fluid handling systems where corrosion resistance and ease of maintenance are required.

Applications:

The 507369 Union is designed to join two sections of threaded pipe while allowing easy disassembly for maintenance, inspection, or equipment replacement. It is commonly used in process piping, chemical plants, refineries, water treatment facilities, and industrial fluid systems where stainless steel construction and corrosion resistance are essential. ASTM A182 F304 unions are widely used in applications requiring frequent connection and disconnection of piping components.
