Bronze Straight Adapter for Potable Water

The Viega 79450 is a bronze crimp adapter fitting designed for potable water applications. It connects a 1 in FTG copper tube to a 1 in FNPT pipe thread in a straight configuration. The fitting features an EPDM O-ring seal and measures 2 in overall length.

Suited for Copper-to-Thread Transitions

This adapter suits installers joining 1 in copper tubing to 1 in female NPT threads in potable water systems. It is not intended for gas lines, drainage waste vent systems, or applications exceeding the rated pressure and temperature limits. Buyers needing flanged connections, reducing sizes, or different thread standards should select another fitting.

Rated 200 psi at 250 Degrees F Maximum

The single specification that decides fit is the maximum operating pressure of 200 psi combined with a maximum operating temperature of 250 Degrees F. Both limits must cover the system design conditions; if either value is exceeded, this adapter is not the correct part.

Questions about this item

Does the Viega 79450 adapter generate heat or noise when water runs through it continuously?

The bronze straight adapter has no moving parts, so it produces no noise and negligible heat during constant water flow.

Which piping components must I already have to install this FTG × FNPT fitting?

You need a 1 in copper tube for the FTG crimp end and a 1 in male NPT threaded pipe for the FNPT end, plus a compatible crimp tool and EPDM O-ring lubricant.

Will the 200 psi / 250 °F rating of this bronze adapter match older copper and threaded lines in my system?

Yes, the 200 psi maximum pressure and 250 °F maximum temperature align with standard 1 in copper and NPT piping, allowing direct integration with existing lines.
