2" ProPress x 2" FNPT Adapter (Lead-Free Bronze)
The 2" ProPress x 2" FNPT Adapter, identified by Manufacturer Part Number (MPN) Viega 79370 (Model 2912ZL), is a high-quality, lead-free bronze fitting designed to create secure and versatile connections between copper tubing and female NPT threaded components. This adapter is specifically engineered for 2-inch nominal pipe sizes, making it an essential component for a wide range of plumbing, HVAC, and industrial applications.
Constructed from lead-free bronze, this ProPress adapter ensures safe use in potable water systems and complies with rigorous standards like NSF 61-G. It features a ProPress connection on one end for copper tubing (ASTM B88) and a Female NPT (FNPT) threaded connection on the other, allowing for flexible system integration.
The core advantage of this adapter lies in its ProPress technology, which enables extremely fast and easy installation. Connections can be made in just four to seven seconds with a single squeeze of a press tool's trigger, completely eliminating the need for flame, solder, or flux. This not only requires less equipment but also promotes cleaner and safer working environments by avoiding hot work permits or fire watches.
A crucial safety and efficiency feature is Viega's patented Smart Connect® technology. This innovation helps installers quickly and accurately identify any unpressed connections during pressure testing, ensuring proper installation and minimizing costly callbacks. The adapter integrates an EPDM (Ethylene Propylene Diene Monomer) sealing element (identifiable by a green dot) to achieve a consistent, strong, reliable, and watertight seal, providing a permanent connection. Its ability to join wet connections further minimizes system downtime, making it an ideal solution for maintenance and emergency repairs. The fitting is robust, rated for 200 psi and an operating temperature range of 0°F to 250°F. It is a versatile choice for applications including hydronic heating, chilled water, compressed air, non-medical gases, fire sprinkler systems, and low-pressure steam, in both new construction and renovation projects.
