Threaded Fitting Stainless Steel Reducing Coupling 2" IG x 1 1/4" IG
Threaded Fitting Stainless Steel Reducing Coupling 2" IG x 1 1/4" IG
Reducing coupling with internal threads on both sides for reducing pipelines. To seal the thread, you additionally need a suitable thread sealing material. Hemp or Teflon tape is suitable here. The thread is the common Whitworth pipe thread used in water technology. The external threads are conical.

Advantages of Stainless Steel Fittings:
All stainless steel fittings listed here are permanently corrosion-resistant and can be detached unlike welded fittings or press fittings. The threads allow a seamless transition to other materials without the need for a transition fitting. The stainless steel fittings do not require seals, making use up to 200 °C possible without any issues.
Thread Type:
The threads of all pipe fittings are manufactured according to the common standards ISO 7-1/EN 10226-1 (internal and external threads) as well as ISO 228-1 (union nuts of the fittings). The external threads are conical/tapered. The internal threads are parallel/cylindrical. All threads are standardly specified in inches. The threads are sealed with a suitable thread sealing material such as PTFE thread sealing tape or thread sealing hemp.

Drinking Water Suitability:
Stainless steel fittings made of AISI 316 stainless steel are listed in the UBA list (UBA = Federal Environment Agency) for drinking water suitable materials in drinking water installation and can therefore be used for drinking water supply.
