SKU CH-CXVM-GAM3Z

Copper press-fit adapter with male NPT thread for 3-inch potable water lines, rated to 200 psi and 250 °F

  • Press-fit copper joint installs without soldering
  • EPDM O-ring seals potable water up to 200 psi
  • Rated for 250 °F continuous service temperature
  • Straight adapter connects 3 in press to 3 in MNPT
  • Meets ASTM B75 and B88 material standards

3 in Copper Press-Fit Adapter

The Viega ProPress 0911XL is a straight copper adapter that joins a 3 in press-fit connection to a 3 in male NPT thread. It is designed for potable water systems and carries an EPDM O-ring for a watertight seal. The fitting meets ASTM B75 and ASTM B88 standards for copper tube quality.

Press-Fit System Limits

The press-fit joint requires a compatible ProPress tool and jaw set to create a permanent mechanical seal. Once pressed the connection cannot be disassembled or repositioned without cutting the tube. The adapter is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 Degrees F.

3 in Male NPT Thread End

The adapter transitions from press-fit to a 3 in male NPT thread, so it only fits components with a matching female NPT port. Installations that require a female thread, a smaller pipe size or a sweat connection will need a different fitting.

Questions about this item

How do I choose the correct version of the Viega ProPress 0911XL copper adapter for my pipe size?

The adapter is made for a 3 in copper tube on the press-fit side and a 3 in male NPT thread on the other side, so match both diameters to your piping.

What does the 200 psi maximum operating pressure mean once the fitting is installed in a potable water system?

It sets the highest continuous pressure the joint can safely handle at up to 250 degrees F, so design your system to stay below that limit.

Which standard governs the press-fit connection and what does it cap in practice?

The press-fit end follows ASTM B88 for copper tube dimensions, which defines the exact outside diameter and wall thickness the tool must seal against.
