## Long description

SiGMA-Li R7550 external 75/50 reducer fitting provides a mechanical transition between pipes with 75 mm and 50 mm diameters. Designed for use in plumbing and drainage systems, this reducer creates a secure external connection that maintains flow direction while adapting pipe size. The component is suitable for residential and light commercial installations where a reliable diameter reduction is required without altering pipe alignment.
Advantages
The external reducer offers a simple mechanical join that does not require complex tools or adhesive bonding for basic installation. Its stepped design supports stable alignment between larger and smaller pipes and reduces the need for additional couplings. The fitting is manufactured to standard dimensions for compatibility with common 75 mm and 50 mm pipe systems, helping to ensure a consistent fit and leak-resistant performance when installed correctly.
Suitable for
Transitioning from 75 mm to 50 mm pipes in drainage systems

Key specifications
Function: external reducer for pipe diameter transition

How to use
Ensure both pipes are clean, free of debris and cut squarely before attempting connection. Slide the reducer over the larger pipe or align it with the smaller pipe according to the installation orientation required. Push the pipes into position until they seat firmly on the respective steps of the fitting. Verify alignment and make any necessary mechanical fixes or clamps according to local installation practice. After installation, inspect joints for secure seating and test the system for leaks under normal operating conditions.
Usage recommendations
Use the fitting in systems within the intended diameter range and install in accordance with local plumbing codes. For pressurized or high-risk installations, supplement the mechanical joint with appropriate clamps or sealing methods and perform pressure testing after installation. Replace any fitting that shows signs of damage or deformation prior to use.
