This union fitting is designed to join two 3/4 in press-fit connections quickly and securely using technology, eliminating the need for soldering, welding, or open flames. Constructed from durable bronze with a lead-free design and EPDM sealing element, it delivers a consistent watertight connection for potable water, hydronic heating, cooling and compressed air applications. This feature helps installers identify unpressed joints during pressure testing and allows press connections to be made wet or dry for faster installation.
