Press-Fit Bronze Adapter

The Viega 79270 ProPress adapter joins 1-1/2 inch copper tube to a 1-1/4 inch male NPT thread using a press-fit connection. Its bronze body and EPDM O-ring handle potable-water service at up to 200 psi and 250 degrees F. The straight adapter measures 2-3/4 inches overall and meets ASTM B75 and ASTM B88 standards.

Suited for press-tool installers.

Plumbers equipped with a compatible press tool can make a flameless, solder-free joint in seconds, ideal for repairs or new potable-water lines. Installers who only have threading or soldering equipment cannot use the press-fit end and should select a different fitting type.

1-1/2 inch press to 1-1/4 inch MNPT

The single specification that decides fitment is the combination of a 1-1/2 inch press-fit copper tube size on one side and a 1-1/4 inch male NPT thread on the other; if either dimension or connection style differs from your piping, this adapter will not work.

Questions about this item

How much heat can the bronze adapter and EPDM seal handle during continuous hot-water service?

The fitting is rated for a maximum operating temperature of 250 Degrees F, so the bronze body and EPDM O-ring remain stable under sustained hot-water conditions.

What press tool and jaw size are needed to make the 1-1/2" press connection?

A Viega ProPress-compatible tool with a 1-1/2" jaw is required to crimp the press-fit end onto copper tube.

Can the 1-1/4" male NPT thread mate with existing galvanised or brass fittings?

Yes, the 1-1/4" MNPT end follows standard NPT threading and will engage older galvanised or brass fittings when sealed with appropriate thread compound.
