Flamco T-Plus DN40 × Rp 1¼" cast iron tapping saddle, PN 25
- Pipe size: DN40 (1½", ~48 mm OD)
- Branch connection: Rp 1¼" female thread
- Working pressure / temperature: PN 25 / up to 130 °C
- Body material: cast iron with anti-corrosion coating
Where T-Plus DN40 is used
The tapping saddle enables new branches on a live piping network without draining or welding. Ideal case — an existing multi-family substation or commercial network where a new heating/cooling zone, DHW line, additional pump, or measurement point must be added. Installation: clamp body around the pipe → activate the single-shot piercing mechanism → integrated seal isolates the cut → connect the new line to the Rp 1¼" thread. The system stays pressurised throughout.

Frequently asked questions
Can it really be installed without shutdown?
Yes — that is the T-Plus core purpose. Branching happens on a live pipeline up to PN 25. Integrated seals and the single-shot piercing mechanism seal the body before piercing the pipe wall.
Suitable for copper pipes?
No — this version (cast iron body) targets thick-wall steel pipes only. For copper, Flamco offers a dedicated brass T-Plus variant — contact us for the correct part number.
What is the branch connection?
Rp 1¼" female thread (ISO 7-1). You can attach flange, socket, or compression adapters as required.
Can it be reinstalled after a single piercing?
No — the piercing mechanism is single-shot. The body can only be removed after draining the system; a new installation requires a new T-Plus.
What is the warranty?
Standard Flamco warranty — 1 year (extended terms available under project agreement — contact us).
