## Summary description

ODLEWNIA reducing coupling 2½" x 2" (model 3, MPN 3-65-50-CZARNA) is a black cast fitting for joining pipes of different diameters. Designed as a threaded/reducing sleeve, it provides a secure connection between 2½-inch and 2-inch pipelines. Suitable for plumbing and industrial fluid systems where diameter transition is required.

## Long description

ODLEWNIA reducing coupling 2½" x 2" model 3 is a black cast threaded reducing sleeve designed to join pipes of different diameters. Made for secure connections between a 2½-inch pipe and a 2-inch pipe, this coupling is suitable for plumbing and industrial fluid systems where a reliable diameter transition is required. The product is supplied in a dark finish and features internal threads to mate with compatible threaded pipe ends.
Advantages
The cast construction offers mechanical strength and resistance to deformation under typical piping loads. Internal threading provides a tight mechanical connection that simplifies installation and ensures leak-resistant joints when used with appropriate sealing materials. The black finish can help with corrosion resistance in certain environments and creates a uniform appearance when integrated into dark-colored piping systems.
Suitable for
Connecting a 2½" pipe to a 2" pipe in water supply and drainage systems
Use in industrial fluid lines where a threaded, stepped transition is required
Plumbing repairs and retrofits where different pipe diameters must be joined
Environments where a durable cast fitting is preferred over lighter materials
When it may not be suitable
This reducing coupling is intended for threaded pipe systems and will not be suitable for solvent-welded, push-fit, or flanged connections. It is not designed for use where welds, compression fittings, or non-threaded mechanical joints are required. For applications involving aggressive chemical exposure or extremely high temperatures and pressures outside common plumbing or standard industrial ranges, select a fitting with verified chemical and thermal ratings.
Key specifications
Connection type: threaded reducing sleeve
Input diameter: 2½ inches
Output diameter: 2 inches
Material: cast metal
Finish: black
How to use
Prepare the mating pipe ends by cleaning threads and removing debris. Apply an appropriate thread sealant or plumber's tape to the male threads to ensure a leak-resistant joint. Hand-start the coupling onto the male thread, then tighten with a suitable wrench until fully engaged and secure; avoid over-tightening to prevent thread damage. Inspect the assembled joint and pressure-test the system according to local codes and application requirements.
What to consider before purchase
Confirm pipe thread type and compatibility with the coupling's internal threads
Verify that cast metal and black finish meet the site's corrosion and mechanical requirements
Ensure the size transition (2½" to 2") matches your piping layout and flow needs
Check operating pressure and temperature of your system against the material capabilities
Usage recommendations
Use approved thread sealants and follow standard installation torque guidelines. For critical systems, perform pressure testing after installation and inspect periodically for signs of corrosion or loosening. When in doubt about chemical compatibility or extreme service conditions, consult a materials engineer or choose a coupling specified for those environments.
