It is intended for use where a reliable external connection is required to adapt fittings or hoses of the specified diameters.

## Long description

Alkotest R4032 is an external reducer designed to join pipes with outer diameters of 40 mm and 32 mm. Manufactured by Alkotest, this adapter creates a mechanical transition between two pipe sizes for plumbing and fluid-transfer systems. The R4032 reducer is intended for external mounting where a stable, simple connection is required to adapt fittings, hoses or rigid pipes of the specified diameters.
Advantages
The external design allows the adapter to fit over pipe ends without modifying the inner bore, simplifying installation and reducing the need for additional fittings. Constructed to provide a reliable mechanical connection, the reducer maintains alignment between connected pipes and supports straightforward removal or replacement. Its geometry ensures consistent outer engagement for common 40 mm to 32 mm transitions used in domestic and light commercial piping applications.
Suitable for
 Connecting a 40 mm outer-diameter pipe to a 32 mm outer-diameter pipe
 Adapting hoses or fittings in plumbing and fluid-transfer lines
 External joint solutions where internal access is limited
 Temporary or permanent pipe reductions in small-scale installations
Key specifications
 Type: external reducer / adapter
 Input outer diameter: 40 mm (external connection side)
 Output outer diameter: 32 mm (external connection side)
 Application: plumbing and fluid-transfer systems
 Connection method: external slip-fit adapter for mechanical joining
How to use
Ensure the pipe ends are clean and free from debris, burrs or corrosion before installation. Slide the larger end of the reducer over the 40 mm pipe outer surface and align the smaller end with the 32 mm pipe outer surface. For a secure fit, use appropriate clamping methods such as hose clamps, clamps with screws, or compatible fastening systems according to the installation requirements and material compatibility. Verify alignment and leak tightness after assembly and retighten clamps as needed.
Usage recommendations
Use the Alkotest R4032 reducer only for adapting the specified outer diameters. Select clamps and sealing materials compatible with the pipe materials and the fluids in the system. Avoid subjecting the adapter to axial loads or pressure levels beyond what the connected pipes and clamping arrangement are designed to withstand. Periodically inspect the external joint for signs of wear, slippage or leaks, especially after temperature cycles or mechanical stress.
