  • Operates from 0 to 250 °F across hot and cold systems
  • Viega ProPress model 77747 ensures consistent, leak-free joints

Copper cross-over coupling 77747

The Viega 77747 ProPress cross-over coupling joins two 3/4-inch copper tubes in a press-to-press configuration. Rated for 200 psi and a temperature range of 0 to 250 degrees F, it suits hot and cold potable-water lines in residential and light-commercial plumbing. Installers who need a compact directional change without soldering will find the press connection reduces joint time and eliminates open flame on site.

Press-ready design with no extra parts

The fitting arrives ready to press; no flux, solder, threading tools or separate sealing rings are required. A compatible press tool and jaw set complete the joint in seconds, cutting labour compared with traditional sweat or threaded methods. The copper body maintains system compatibility and corrosion resistance without introducing dissimilar metals. Buyers who need threaded ends, larger diameters or a different fitting style will need another product.

Questions about this item

Does the copper press fitting require any periodic re-pressing or seal replacement after installation?

The copper press fitting creates a permanent mechanical seal that does not require re-pressing or scheduled seal replacement under normal conditions.

Will the 200 psi pressure rating or the 250 °F temperature limit be reached first in a hot-water recirculation loop?

The 250 °F temperature limit is reached before the 200 psi pressure rating in typical hot-water recirculation loops.
