Coupling 42 mm - thin-walled galvanized carbon steel, crimped PC5270 0420000

Robust Connection for Steel Installations

The 42 mm diameter coupling is a component of the press-fit system, designed for durable joining of carbon steel pipes. Thanks to the use of electro-galvanization, the fitting is corrosion-resistant, which is crucial in water and industrial installations. The one-piece construction with a stop flange ensures precise pipe centering during assembly, eliminating the risk of misalignment before proper pressing. A maximum working pressure of 16 bar at 20°C makes this element suitable for standard installation circuits where leak-tightness and mechanical strength are required.

Quick and Safe Installation Without Open Flame

The main advantage of this solution is the joining method, which completely eliminates the need for welding or threading. The process involves inserting the pipe fully into the coupling socket, followed by using specialized pressing jaws. This action deforms both the EPDM gasket and the steel structure itself, creating a mechanical and hermetic seal simultaneously.

For the installer, this means:

• No fire risk – work near flammable materials is safe.
• Fast execution – one connection takes a fraction of the time required by traditional methods.
• Visual inspection – the stop flange allows easy verification that the pipe has been inserted to the correct depth before pressing.

The gasket made of ethylene-propylene-diene rubber (EPDM) guarantees tightness even under temperature fluctuations, and the lack of need for additional gaskets or assembly pastes simplifies on-site logistics.

Application and Technical Characteristics

This component is dedicated to installation systems requiring permanent and non-reversible connections. Its design allows installation in areas with limited accessibility, where traditional welding tools cannot operate. With a length of 84 mm and an outer diameter of 42 mm, the coupling maintains a compact form, facilitating pipe laying in tight shafts or under suspended ceilings.

Key operational parameters include galvanized carbon steel as a material ensuring high resistance to mechanical loads, and the pressing method guaranteeing a durable connection without the risk of leaks resulting from human error during threading. The 42 mm diameter is a universal size for medium-diameter installations (e.g., heating systems, process water), and the 16 bar working pressure is sufficient for most residential and public buildings.

It is important to remember that after pressing, the connection becomes permanent and cannot be disassembled without cutting the system components. Therefore, it is crucial to carefully check pipe alignment before the pressing moment. This coupling does not have a drain valve or air vent, meaning it is intended solely as a straight connector between two pipe sections of the same nominal diameter.
