## Long description

Threaded reducing coupling INVENA ZM-10-153 is a female-to-male adapter with internal 3/4" and external 1/2" threads. It is designed to connect pipes or fittings with different thread sizes and provides a secure, sealed transition between 3/4" and 1/2" threaded components. The adapter is intended for use in plumbing installations, repairs and modifications where a reliable threaded connection is required.
Advantages
The reducing coupling offers a compact solution for adapting between two common thread sizes without the need to replace existing fittings. Its female-to-male configuration simplifies installation in tight spaces and reduces the number of additional parts. The component provides a stable mechanical connection and maintains thread compatibility with standard 3/4" and 1/2" plumbing fittings.
Suitable for
Connecting 3/4" internal-thread fittings to 1/2" external-thread pipes or components
Plumbing repairs where thread size conversion is required
System modifications in residential and commercial water installations
Key specifications
Type: reducing coupling, female-to-male threaded adapter
Thread sizes: internal 3/4" and external 1/2"
Application: plumbing connections and thread size conversion
Installation: threaded connection
Typical materials: metal commonly used for plumbing fittings (verify material with product label)
How to use
Ensure that mating threads on pipes or fittings are clean and free of debris or damage before assembly. Apply appropriate thread sealant or PTFE tape to the male thread if a watertight seal is required.

After installation, check the connection for leaks and retighten if necessary following recommended torque for the fitting material.
Usage recommendations
Use compatible sealing materials for potable water systems when applicable, and confirm the adapter material and pressure ratings are suitable for the intended application. For installations involving high temperatures, high pressure, or aggressive fluids, verify compatibility with the system specifications or consult a professional.
