Frequently Asked Questions

What is a NIBCO sweat fitting union used for?

A NIBCO sweat fitting union connects two copper pipes in plumbing and HVAC systems, allowing easy disconnection for maintenance. This bronze union joins 1 in CTS copper tube to 1 in pipe via a cup x FNPT connection, ensuring leak-free performance in potable water and hydronic heating applications.

What are the specifications of the NIBCO 7333 1 union?

The NIBCO 7333 1 is a cast bronze sweat fitting union with a cup x FNPT connection. It fits 1 in CTS copper tube on one side and 1 in pipe on the other. The bronze construction resists corrosion, making it suitable for water and steam systems up to 150 psi.

How to install a NIBCO sweat fitting union?
