Clamping Ring FORTIS 75/63 — pipe reducer coupling 75 mm to 63 mm

Clamping Ring FORTIS 75/63 is a mechanical reducer coupling designed to join pipes with outer diameters of 75 mm and 63 mm. It creates a compressive connection that adapts two pipe sizes into a secure joint suitable for plumbing, HVAC and drainage applications. The reducer is intended for repair, retrofit and new installation work where a reliable seal and mechanical fixation between different pipe diameters is required.

Advantages

The clamping ring provides a robust, non-permanent connection that resists axial and radial movement while maintaining a tight seal. Its simple mechanical design allows fast installation without specialized equipment and enables easy disassembly or adjustment if needed. The coupling is compatible with common rigid and semi-rigid pipe materials used in building services, offering consistent compression around the pipe circumference to reduce the risk of leaks.

Suitable for

• Connecting a 75 mm pipe to a 63 mm pipe in drainage systems
• Adapting pipe sizes in residential and commercial plumbing
• HVAC duct and condensate line connections requiring a mechanical seal
• Repairing or retrofitting existing pipework where welding or solvent joining is not possible

Key specifications

• Connection type: clamping ring / mechanical reducer coupling
• Outer diameter compatibility: 75 mm to 63 mm
• Function: compressive joint providing mechanical fixation and sealing
• Suitable pipe materials: common rigid and semi-rigid plastics and compatible metal pipes (where mechanical clamping is acceptable)
• Application areas: plumbing, drainage, HVAC, repair and retrofit work

How to use

Ensure both pipe ends are clean, free of debris and cut squarely. Slide the clamping ring over the larger pipe end or position it between the two mating pipe ends so that the 75 mm side aligns with the larger pipe and the 63 mm side with the smaller pipe. Center the reducer on the joint and tighten the clamping mechanism evenly according to the manufacturer's torque guidance or until a secure, uniform compression is achieved. After installation, check for axial movement and perform a pressure or leak test appropriate to the system to confirm sealing integrity.

Usage recommendations

Inspect pipe surfaces for damage or irregularities before installation, and avoid overtightening which can deform pipe ends or compromise the sealing element. Select a clamping ring compatible with the pipe material and operating conditions (temperature, pressure, chemicals). For pressurized systems or where access is limited, follow applicable standards and testing procedures after installation.
