Double coupling with SC 42 x 6/4" stainless steel - stainless / polished, model 2362 Sanpress 437558

SC‑Contur Transition Fitting – Robust Pipe and Thread Connection

The SC‑Contur series double connector combines the advantages of a press-fit steel coupling and a metric internal thread. This enables quick and secure connection of a pipe with an outer diameter of 42 mm (1 ½ ") to a threaded component without the need for additional adapters. The one-piece construction eliminates the risk of leaks at the joint interface, while the polished surface finish is ideal for both hygienic and aesthetic applications.

Key Features and Practical Benefits

• Material – Entirely made of stainless steel, ensuring corrosion resistance and long-term durability in water and heating installations.
• Sealing – A flat EPDM (ethylene-propylene-diene monomer) gasket guarantees leak-tight performance at a maximum operating pressure of 16 bar at 20 °C and within temperature ranges from ‑25 °C to 85 °C.
• Connections – One side features a press-fit coupling (MZ) designed for system pipes; the other side has a GWM internal thread with a dimension of 1 ½ " (40 mm), enabling connection to standard fittings.
• One-piece construction – The absence of additional assembly components for tightening reduces potential failure points and accelerates installation.
• Nickel-plated brass nut – Provides additional corrosion protection at the interface with metal components.
• Compatibility with the VIEGA SC‑Contur system – Perfect fit for existing VIEGA sanitary and heating systems.

Applications and Practical Tips

This double connector is suitable for:

• central heating installations,
• domestic hot water networks,
• cooling systems operating within the specified temperature range,
• modernization of existing connections where rapid replacement without cutting pipes is required.

During installation, simply:

1. Press the coupling onto the prepared system pipe (outer diameter 42 mm).
2. Tighten the nut (using a multi-sided wrench) until the EPDM gasket is evenly compressed.
3. Attach the threaded component – thanks to the precise GWM thread, the connection is stable and requires no additional seals.

Thanks to this design, installers save time, while end users receive a reliable and durable system with no risk of leaks.
