  • Meets ASTM B75 and B88 standards for quality assurance

Bronze Press-Fit Adapter

The Viega ProPress 2911ZL is a straight bronze adapter that joins 1-1/2 in copper tubing to a 1-1/2 in male NPT thread. It is designed for potable water systems and installs with a standard press tool instead of solder or thread sealant.

Capacity and Headroom

The fitting handles a maximum operating pressure of 200 psi and a maximum operating temperature of 250 Degrees F. The EPDM O-ring seals the press connection, while the bronze body resists corrosion in water service. The adapter runs out of headroom when system pressure or temperature exceeds those rated limits.

Critical Specification

The defining detail is the press-fit connection on the copper side paired with a 1-1/2 in MNPT thread on the other. If the installation calls for a soldered joint, a threaded female end, or a different tube size, this adapter will not fit the piping scheme.

Questions about this item

Will the 1-1/2 in press-fit end join my existing 1-1/2 in copper tube?

Yes, the press-fit end is sized for 1-1/2 in copper tube and the EPDM O-ring seals when pressed with a standard ProPress jaw.

How can I confirm the joint is leak-free after pressing?

Pressurise the system up to 200 psi at no more than 250 °F; a sound joint shows no pressure drop and no moisture at the adapter.

Does the 2911ZL box include press jaws or pipe dope?

The box contains only the bronze straight adapter with its factory-fitted EPDM O-ring; press jaws and thread sealant are purchased separately.
