## Long description

ODLEWNIA model 40-20-10-CZARNA is a black reducing nipple with male threaded connections 3/4" x 3/8" designed for joining pipes or fixtures with different thread sizes. The fitting provides a compact mechanical transition between a larger 3/4" thread and a smaller 3/8" thread, suitable for plumbing adaptations, retrofit work and basic fluid installations. The product is metal, finished in black, and has an approximate weight of 0.083 kg.
Advantages
The ODLEWNIA nipple reducer offers a straightforward threaded connection that requires no soldering or welding, enabling quick installation or replacement. Its reducing design allows compatibility between mismatched thread sizes while maintaining a sealed mechanical joint when used with appropriate sealing tape or compound. The black surface finish provides a consistent appearance for visible connections and may offer additional protection against surface wear.
Suitable for
 Plumbing repairs where a 3/4" male thread must be adapted to 3/8" male thread
 Retrofitting fixtures or appliances with differing thread sizes
 Temporary or permanent mechanical connections in water supply or non-aggressive fluid lines
 Workshop use and on-site pipe adaptations
When it may not be suitable
This threaded nipple is intended for mechanical thread-to-thread connections and is not a substitute for specialized fittings required in high-pressure, high-temperature, or corrosive chemical environments unless material compatibility and ratings are verified. It should not be used where a welded or soldered joint is specifically required by local codes or where an internal sealing gasket is necessary for the application.
Key specifications
 Thread connections: male 3/4" x male 3/8"
 Function: reducing nipple (mechanical threaded adapter)
 Finish: black
 Approximate weight: 0.083 kg
 Typical use: plumbing adaptations and retrofit work
How to use
Wrap appropriate thread sealant tape or apply liquid thread sealant to the male threads before assembly to ensure a leak-resistant joint. Thread the nipple into the corresponding female fittings by hand to start, then tighten with an appropriate wrench until secure, avoiding excessive force that could damage threads. Inspect the connection for leaks after pressurizing the system and re-tighten or reseal if necessary. Ensure thread types and sizes match mating fittings to prevent cross-threading.
What to consider before purchase
 Confirm that both mating fittings use compatible thread types and sizes (3/4" and 3/8" male threads)
 Verify material compatibility with the fluid and operating conditions (temperature, pressure, corrosiveness)
 Check local plumbing codes for requirements on joints and permitted fittings
 Plan for appropriate sealing method (PTFE tape or thread sealant) and necessary tools for installation
Usage recommendations
 Use the ODLEWNIA 40-20-10-CZARNA nipple with properly matched female fittings and standard thread sealing practices. For pressurized systems, perform a controlled leak test after installation and follow applicable installation standards to ensure reliable operation.
