Tee with SC 15 x 3/8" x 15 bronze / glossy, model 22172 313951

Tee with press fittings and internal thread 3/8"

Made of raw bronze, equipped with integrated EPDM seals – no additional sealing required during installation. The press fitting connections (SC-Contur) ensure leak-tightness already at the first press, and an incorrectly connected pipe is visible during the pressure test – no need to guess whether the connection is correct.

One component connects three circuits: two 15 mm lines (for copper pipes) and one internal thread Rp 3/8". This solution is ideal for connecting devices – e.g., faucets, valves, radiators – where branching is required without additional adapters. The internal thread allows direct screwing of a valve or regulator, eliminating the need for threaded pipes.

All surfaces are uncoated – no chrome plating or paint. This is not a defect, but a conscious choice: the installer knows there is no protective layer that could flake off or interfere with the pressing process. Bronze is resistant to corrosion in water and heating systems, and EPDM complies with standards for potable water and temperatures up to 110°C.

Operating pressure up to 16 bar at 20°C – sufficient for heating and water supply systems even under high loads. Operating temperature from -25°C to 110°C allows use in both underfloor installations and boiler rooms.

Wrench width 21 mm – standard for most Viega pressing tools. Simple installation: insert the pipe, press with the tool – and you have a leak-tight connection. No soldering, no gluing, no waiting for curing.

There are no "magic" features here. This is a structural component – simple, proven, without unnecessary embellishments. For the installer: fast installation and certainty of the result. For the user: no leaks for years.
