## Summary description

Threaded reducer coupling from Niczuk converting an external M10 thread to an internal M16 thread. Mechanical metal fitting designed to join or adapt components with different metric thread sizes. Suitable for plumbing, mechanical assemblies, or repair tasks where M10 male parts must be connected to M16 female fittings. Simple installation with threaded engagement.

## Long description

Threaded reducer coupling Niczuk, external M10 to internal M16 is a mechanical metal fitting designed to convert an external M10 threaded male connection into an internal M16 female thread. The coupling enables safe and stable joining of components with different metric thread sizes and is intended for situations where an M10 male part must be adapted to fit an M16 female counterpart. The product is made of metal and uses standard metric thread profiles to provide a straightforward threaded engagement and mechanical connection.
Advantages
The reducer coupling offers a simple, compact solution for adapting metric threads without the need for welding or machining. Its metal construction ensures mechanical strength and wear resistance under normal assembly conditions. The threaded design allows quick installation and removal, making it convenient for repair work and temporary assemblies. Because it uses standard M10 and M16 metric threads, it is compatible with commonly available components and tools.
Suitable for
 Adapting an external M10 male thread to an internal M16 female fitting
 Plumbing connections where metric adapters are required
 Mechanical assemblies and repair work involving mixed thread sizes
 Prototyping or temporary fixtures that need reversible threaded joins
Key specifications
 Thread conversion: external M10 to internal M16
 Material: metal (mechanical fitting)
 Thread standard: metric thread profiles for M10 and M16
 Connection type: threaded reducer coupling for joining dissimilar thread sizes
 Installation: threaded engagement for assembly and disassembly
How to use
Ensure mating parts are clean and free of debris or damaged threads before installation. Screw the reducer coupling onto the external M10 male thread by hand to start, then tighten with an appropriate wrench until secure without over-torquing. Insert or engage the M16 female component into the internal thread and tighten as required for the application. For disassembly, reverse the procedure, taking care to avoid cross-threading during reinstallation.
Usage recommendations
Use standard thread lubricants or anti-seize compounds if exposure to moisture or corrosive environments is expected. Check thread compatibility and fit before final assembly, and avoid excessive torque to prevent thread deformation. For pressurised plumbing systems, verify sealing requirements separately, as the reducer coupling provides mechanical connection and may require additional sealing elements such as thread tape or sealant depending on the application.
