## Long description

OPERATIVE reducer 100/105-90/75 black model 3106230 (S) is a stepped pipe reducer designed to join pipes or fittings with different outer diameters. It provides a mechanical transition from 100/105 mm to 90/75 mm and is intended for use in plumbing and HVAC systems where a reliable, aligned connection is required. The reducer is finished in black, offers a compact profile, and simplifies connections between mismatched pipe sizes without the need for complex adaptations.
Advantages
The reducer ensures precise alignment between pipes of two different diameters and supports a secure mechanical joint. Its stepped design reduces the need for additional adapters and shortens installation time. The black finish provides a neutral appearance that fits many system layouts, while the compact shape conserves space in confined installations. Manufactured for ease of handling, it enables straightforward insertion and positioning during assembly.
Suitable for
Plumbing systems requiring transition between 100/105 mm and 90/75 mm pipes
HVAC duct or pipe connections where stepped reduction is needed
Repair or retrofit jobs when matching different pipe diameters
Mechanical assemblies needing a compact, aligned pipe join
Key specifications
Material: compatible with standard plumbing and HVAC piping materials (mechanical reducer design)
Outer diameter transition: from 100/105 mm to 90/75 mm
Finish/color: black
Design: stepped reducer with two offset diameters for secure alignment
Profile: compact form factor for space-limited installations
How to use
Ensure both pipe ends are clean and free of debris before installation. Slide the larger end of the reducer onto the pipe with the corresponding outer diameter, then align and insert the smaller end into the mating pipe or fitting. Verify axial alignment and secure connections according to the installation practice for the materials in use—this may include mechanical clamps, seals, or adhesive compatible with the pipe material. Check the joint for correct seating and, if applicable, perform a pressure or leak test following system requirements.
Usage recommendations
Select clamps or sealing methods that match the pipe material and operating conditions. Avoid excessive force during assembly to prevent deformation of the stepped sections. If the system will carry fluids under pressure or operate at elevated temperatures, confirm material compatibility and confirm that sealing elements are suitable for the operating range.
