Slip coupling 76.1 bronze / shiny, model 22155XL 353315

Practical solution for water‑heating and industrial installations

The 76.1 mm sliding coupling in a one‑piece version enables quick and secure connection of pipes of the same diameter without the need for soldering. Thanks to its simple shape (0° angle) and length of 115 mm, it is ideal for both under‑floor and above‑floor installations, as well as in hard‑to‑reach locations where traditional fittings would be inconvenient.

Key construction features

• Material – body made of raw‑surface bronze (rotguss), ensuring good corrosion resistance and ease of machining during installation.
• Press system – designed for SC‑Contur press fittings; the connection is permanently secured under high pressure, and improperly pressed elements are immediately detectable during the leak test.
• Sealing – built‑in seal made of monomeric EPDM rubber (EDPM) guarantees a durable barrier against leaks even at the maximum working pressure of 16 bar at 20 °C.

Applications and practical benefits

• Versatile range of applications – suitable for trunk, heating, rainwater, compressed air, inert gas, cooling systems, as well as industrial and building installations.
• High thermal resistance – permissible operating temperature up to 85 °C in water supply installations and up to 110 °C in heating systems, allowing the coupling to be used in a wide range of temperature conditions.
• Easy installation – the one‑piece design eliminates the need for additional components (e.g., drain valves or air vents), reducing installation time and minimizing potential failure points.
• Operational safety – the absence of drain valves and air vents eliminates the risk of unintended medium discharge, while the raw surface of the connections ensures even force distribution during pressing.

Why choose this coupling?

• Fast and secure installation – simply fit the pipe into the coupling and use the pressing tool; the connection is ready for operation immediately after pressing.
• Resistance to high pressure – 16 bar at 20 °C ensures stability even in the most demanding water and gas networks.
• Compatibility with the SC‑Contur system – enables automatic detection of improperly secured connections, enhancing quality control of the entire installation.
• Durability thanks to EPDM – the monomeric rubber seal is resistant to aging, UV radiation, and exposure to many chemicals encountered in industrial installations.

The 76.1 mm sliding coupling in the bronze version is a robust component of the VIEGA system, combining installation simplicity with high reliability across a wide range of applications.
