Viega MegaPress Adapter 25115

The Viega MegaPress adapter 25115 is a steel crimp fitting for non-potable water systems. It connects a 1-1/4 inch press-fit pipe to a 1-1/4 inch male NPT thread. The fitting features an EPDM O-ring and a zinc nickel-plated finish for corrosion resistance. It is supplied new for industrial and commercial piping installations.

Press-Fit to MNPT Connection

The single specification that decides fit is the connection transition: Side A uses a 1-1/4 inch press-fit end while Side B provides a 1-1/4 inch male NPT thread. This straight adapter joins dissimilar joint methods without threading the press side. Installers must verify both pipe size and thread standard match the system design.

200 PSI Pressure Rating

The fitting handles a maximum operating pressure of 200 psi in non-potable water applications. Its 3 21/32 inch overall length provides a compact straight run between the press joint and the threaded connection. It is not intended for potable water lines or pressures exceeding the rated limit.

Questions about this item

What does the 200 psi rating mean once the adapter is installed?

The 200 psi rating is the maximum operating pressure the MegaPress adapter can handle in service, so the connected non-potable water system must not exceed that pressure.

What connection standard does the press-fit end use and what does it cap?

The press-fit end follows the MegaPress system and caps the joint at the 200 psi operating limit when crimped with the correct tool and jaw.

What physical space is needed to fit the straight adapter?

The overall length is 3 21/32 in, so allow at least that much straight run between the 1-1/4 in press-fit pipe and the 1-1/4 in MNPT thread.
