Muff 100 mm Krzys-Pol MOC 100 galvanized steel pipe coupling

Krzys-Pol MOC 100 is a 100 mm galvanized steel pipe coupling designed to connect sections of round ducting and piping. Manufactured from corrosion-resistant galvanized steel, the coupling forms a secure mechanical joint suitable for ventilation, drainage and general-purpose industrial installations. The simple cylindrical design ensures compatibility with standard 100 mm round ducts and pipes while offering a robust metal connection for both residential and commercial systems.

Advantages

The galvanized steel construction provides long-term resistance to corrosion and mechanical wear, reducing the need for frequent replacements. The coupling offers a straightforward fit for 100 mm round ducts, enabling fast on-site assembly without specialized tools. Its durable metal build maintains dimensional stability and a reliable seal when installed with appropriate fastening methods, making it suitable for systems where a metal-to-metal connection is preferred over flexible alternatives.

Suitable for

• Connecting 100 mm round ventilation ducts
• Joining sections of drainage and rainwater pipes of matching diameter
• Industrial air handling and exhaust ducting
• Residential HVAC installations requiring metal couplings

Key specifications

• Material: galvanized steel
• Nominal diameter: 100 mm
• Shape: cylindrical coupling (muff)
• Finish: corrosion-resistant zinc coating
• Application: ventilation, drainage, industrial piping

How to use

Ensure both pipe ends are clean and free of burrs or debris before assembly. Slide the coupling onto one pipe end and align the second pipe section, making sure the mating ends are fully inserted for a flush joint. Secure the connection using appropriate metal clamps, rivets or spot welding depending on the application and local installation standards. For ventilation systems, verify airflow direction and ensure any sealing or insulation measures are applied according to system requirements.

Usage recommendations

For optimal performance, install the coupling in dry conditions and avoid exposure to aggressive chemicals that may compromise the galvanised coating. When used in external or high-humidity environments, supplement the mechanical connection with corrosion-resistant fasteners and, if necessary, a compatible sealant to prevent air or water leakage. Follow local building codes and industry guidelines during installation.
