ProPress 2962 Bronze Union

The Viega ProPress 2962ZL is a crimp union fitting designed for potable water systems. It connects a 1/2 in copper tube on the press-fit side to a 1/2 in female NPT thread on the other. The body is made from bronze with an EPDM O-ring.

1/2 in Copper Press to FNPT Transition

The critical specification is the mixed connection type: Side A takes a 1/2 in copper tube via press-fit, while Side B accepts a 1/2 in FNPT thread. This makes it the correct part only when joining copper tubing directly to threaded pipe or valves. It will not work for copper-to-copper or threaded-to-threaded joints.

Press-Tool Installation Requires Correct Jaw

Installation requires a compatible press tool and the correct jaw size for 1/2 in copper. The press creates the permanent seal; no soldering or threading is needed on Side A. Common issues arise from using worn jaws, misaligned tubing, or forgetting to deburr the copper end before pressing. The fitting meets ASTM B75 and B88 standards and is rated for 200 psi at 250 Degrees F.

Questions about this item

What does the 200 psi rating mean once the fitting is installed in a potable-water system?

The bronze union is tested to hold 200 psi continuously, so it will not leak or burst at normal municipal or well-pump pressures in a residential or light-commercial potable-water line.

How does the press-fit connection limit what pipe and tools can be used?

Side A requires 1/2 in copper tube and a compatible ProPress jaw set; the joint is permanent once crimped, so no threading, soldering or other press systems will seal on that end.

What clearance and pipe preparation are needed to mount the 2 9/32 in straight union?

Allow at least the overall length plus room for the press tool jaws; cut the copper tube square, deburr, mark the insertion depth and ensure the EPDM O-ring seats cleanly before crimping.
