  • Bronze construction resists corrosion in potable water systems
  • Press-fit 1/2" connection enables fast, flame-free installation
  • FNPT 3/8" thread mates with standard threaded components
  • 90-degree elbow redirects flow in tight spaces
  • Rated 200 psi at 250°F for demanding hot-water service

Bronze Press-Fit Elbow for Potable Water

The Viega 79520 is a 90-degree elbow adapter that joins 1/2-inch copper tube to a 3/8-inch female NPT thread. Its bronze body and EPDM O-ring suit potable-water systems and meet ASTM B75 and ASTM B88 standards.

Replaces Threaded or Soldered Transitions

Use this fitting when you need a press connection on the copper side and a threaded port on the other, avoiding open flame or pipe dope. The jump is worth it on retrofit jobs where pressing is faster and cleaner than sweating a reducer and a separate adapter.

Press Tool Required for Installation

A compatible press tool and the correct jaw for 1/2-inch copper are essential; the joint will not seal without full compression. Common issues are misaligned tubing, debris on the O-ring, or pressing before the tube is fully seated to the stop.

Questions about this item

What copper tube size and press-fit tool jaw does the 1/2 in connection require?

The fitting accepts 1/2 in copper tube and is pressed with a standard 1/2 in press jaw.

Which step is most often missed when pressing the 90 degree elbow onto the tube?

Insert the tube fully until it stops, check the insertion mark, then press — skipping the depth check causes leaks.

How often should the EPDM O-ring be inspected or replaced in a 200 psi potable water system?

Inspect the O-ring annually; replace it if you see cracking, flattening or after any pressure test failure.
