Pipe reducer OPERATIVE 75/70-50/40 black model 3106360 for diameter transition

OPERATIVE pipe reducer model 3106360 in black is a concentric fitting designed to connect circular pipes with larger diameters (75/70 mm) to smaller diameters (50/40 mm). Intended for inline installation, the reducer ensures a smooth, secure transition between pipe sections in plumbing, ventilation and drainage systems. Its compact shape supports limited space installations while maintaining flow continuity and a stable mechanical joint.

Advantages

The reducer provides a reliable mechanical connection between mismatched pipe diameters and minimizes turbulence at the transition point. Its concentric design keeps the pipe centreline aligned, reducing the risk of flow imbalance. The black finish resists common environmental effects and allows easy identification during installation. The fitting is lightweight and simple to handle, enabling quicker alignment and fastening during assembly.

Suitable for

• Plumbing systems requiring diameter transition between 75/70 mm and 50/40 mm pipes
• Ventilation ducts where concentric diameter reduction is needed
• Drainage and waste systems with circular pipe sections
• Repair or retrofit works where space constraints require compact fittings

Key specifications

• Type: concentric pipe reducer for circular pipes
• Input diameter: 75/70 mm (nominal range)
• Output diameter: 50/40 mm (nominal range)
• Colour: black
• Mounting: inline installation
• Application: plumbing, ventilation, drainage

How to use

Prepare both pipe ends by ensuring they are clean and free of debris. Align the larger pipe to the reducer's larger end and the smaller pipe to the reducer's smaller end, keeping the centreline continuous. Secure connections according to the pipe material and system requirements — this may include clamps, sealant, or adhesive compatible with the pipes in use. Verify the joint for proper fit and absence of leaks before returning the system to service.

Usage recommendations

When installing the reducer, confirm compatibility with the pipe material and local codes. Use appropriate sealing methods for the medium conveyed (water, air or waste) and avoid applying excessive mechanical stress to the fitting. Periodically inspect the transition point for signs of wear, misalignment or leakage, especially in systems subject to thermal cycling or mechanical vibration.
