## Summary description

Cast iron reducer fitting ODLEWNIA model 45-65-40-CZARNA in black finish for connecting pipes with different diameters (2½" to 1½", DN65 to DN40). Designed for plumbing and industrial piping systems, it provides a sturdy, corrosion-resistant joint for fluid transport and installation in water, heating, or drainage networks.

## Long description

ODLEWNIA reducer fitting model 45-65-40-CZARNA is a black cast iron concentric reducer designed to join pipes of different outside diameters — 2½" (DN65) to 1½" (DN40). Intended for plumbing, heating and drainage systems, this reducer creates a robust transition between larger and smaller lines while maintaining structural stability and resistance to mechanical wear. The black finish offers basic protection against surface corrosion and a uniform appearance for exposed sections of piping.
Advantages
The cast iron construction provides high mechanical strength and dimensional stability under typical operating loads. Its concentric design ensures a smooth flow transition between diameters, minimising turbulence and potential pressure losses. The black finish adds a layer of surface protection and gives the fitting a consistent visual finish for installations where appearance is relevant. The component is compatible with common pipe joining methods used in plumbing and industrial piping.
Suitable for
 Connecting DN65 to DN40 pipelines where outside diameters correspond to 2½" and 1½".
 Domestic and commercial water supply lines and circulation systems.
 Heating installations such as radiator feed or return lines where cast iron fittings are specified.
 Drainage and wastewater systems with compatible pipe materials and joining methods.
 Industrial piping applications requiring rigid, mechanical transitions between pipe sizes.
When it may not be suitable
This cast iron reducer is not intended for use with aggressive chemicals, highly acidic or alkaline fluids, or applications needing corrosion-resistant alloys such as stainless steel. It may not be appropriate where flexible or vibration-isolating connections are required, since cast iron is rigid and transmits mechanical stresses. For pressurised systems operating at temperatures or pressures outside standard plumbing ranges, consult technical specifications to ensure material compatibility.
Key specifications
 Material: cast iron
 Finish: black surface coating
 Connection type: concentric reducer (mechanical pipe-to-pipe transition)
 Outer diameter compatibility: 2½" (larger end) to 1½" (smaller end)
 Nominal diameters: DN65 to DN40
 Typical applications: water supply, heating, drainage, industrial piping
How to use
Before installation, verify that the pipe outside diameters and joint method match the reducer's ends. Prepare mating pipe ends by cleaning and deburring; apply appropriate jointing method such as flange bolting, solderless couplings, gasketed joints or compatible mechanical couplers as required by the system. Align the reducer concentrically to ensure smooth flow and tighten fastenings to manufacturer-recommended torque levels. After installation, perform a pressure or leak test according to local plumbing standards and inspect the assembly for correct alignment and sealing.
What to consider before purchase
 Confirm pipe outside diameters and nominal DN sizes (DN65 and DN40) match the reducer ends.
 Check compatibility of cast iron material with the transported fluid and operating temperature/pressure.
 Ensure the chosen joining method (gaskets, flanges, mechanical couplers) is suitable for cast iron.
 Assess whether a concentric reducer is appropriate versus an eccentric reducer for system drainage or air-trapping concerns.
Usage recommendations
Use this ODLEWNIA cast iron reducer in systems where rigid, durable transitions are required. For installations exposed to moisture or potential corrosion, consider additional protective coatings or regular inspections. When replacing or upgrading sections, match material and connection types to maintain consistent system performance and avoid galvanic corrosion between dissimilar metals.
