This size is typically chosen for multi-family substations and medium commercial heating/cooling networks, where DN50 is the main user branch or return line. Used when adding a branch (new pump, measurement point, DHW module, secondary loop) to an operational system — maintaining pressure and flow throughout. Installation time with an experienced technician: 10-15 minutes.

Yes — the integrated seal is engineered for full pipe service life under rated conditions. Seal failure typically only follows body damage or exceeding PN 25 / 130 °C limits.
Rp — per ISO 7-1, a parallel female thread, matching common installation adapters. Verify the mating branch has matching R (tapered) or G (parallel) male thread with sealing.
Yes, up to 50 % ethylene or propylene glycol with appropriate inhibitors. Higher concentrations may impact seal longevity — contact us for specifics.
An installed T-Plus needs no periodic maintenance. A visual annual check is recommended (leak marks, corrosion, connector condition).
Signs: visible moisture on the body, seal-edge corrosion, or pressure drop in the connected branch. Replacement requires system drain-down.
