Viega ProPress tee 1-1/4 x 1-1/4 x 3/4 79775

ProPress Reducing Tee

The Viega ProPress tee connects two 1-1/4 inch copper tubes and a 3/4 inch FNPT branch in a single bronze fitting. It is designed for potable-water systems that require a secure, flame-free press connection. The integral centre-stop dimple helps installers position each tube at the correct depth without measuring. This fitting suits plumbers and contractors who need a reliable reducing tee for residential or commercial supply lines.

Press-Fit Seal and Pressure Rating

Each press-fit end uses an EPDM O-ring that forms a permanent, leak-tight seal when crimped with approved jaws. The bronze body is rated for a maximum operating pressure of 200 psi in normal service. No solder, flux or open flame is required, so installation produces no heat or fumes and keeps the work area quiet. The connection is ready for pressure testing immediately after pressing.

Sustained System Performance

Under continuous system pressure the pressed joints maintain their integrity without relaxation or creep. The bronze construction resists dezincification and corrosion in potable water, preserving flow capacity over the service life. Because the seal is mechanical rather than thermal, temperature cycling does not degrade the joint. The fitting therefore performs consistently in long-term installations where reliability outweighs the need for disassembly.
