  • Press-fit copper eliminates soldering for faster installs
  • Straight reducing adapter connects 1 in FTG to 1/2 in press-fit
  • EPDM O-ring seals potable water up to 200 psi
  • Copper construction meets ASTM B75 and B88 standards

Viega 78082 Straight Reducing Adapter

The Viega 78082 is a copper straight reducing adapter designed for potable water systems. It connects a 1 inch FTG fitting to a 1/2 inch press-fit connection using a crimp fitting method. The EPDM O-ring provides a reliable seal for plumbing installations.

Sustained pressure and temperature performance

The fitting withstands a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees F. Copper construction meets ASTM B75 and ASTM B88 standards for durability under continuous load. These ratings ensure the joint remains secure during prolonged hot water circulation or high pressure supply conditions.

Replaces threaded or soldered reducer fittings

This press-fit adapter replaces traditional soldered or threaded copper reducers where a direct 1 inch to 1/2 inch transition is required. The jump is worth it when installation speed and flame-free connections are priorities on potable water lines. It is not suited for applications requiring a different tube size reduction or a non-copper material.

Questions about this item

How much heat can the Viega 78082 adapter handle in a continuous hot-water loop?

The copper body with EPDM O-ring is rated for a maximum operating temperature of 250 Degrees F, so it will not degrade in standard residential or commercial hot-water circuits.

Which press tool and jaw set are required to install this 1 in FTG by 1/2 in press-fit copper adapter?

You need a press tool compatible with Viega PureFlow or ProPress systems and the correct 1 in and 1/2 in jaw sets; the FTG end slides into a 1 in fitting and the press end accepts 1/2 in tube.

Will the 200 psi pressure rating hold when the adapter connects to older copper pipe sized to ASTM B88?

Yes, the fitting meets ASTM B75 and ASTM B88 standards, so it matches the dimensions and pressure class of existing ASTM B88 copper tube up to the 200 psi limit.
