## Summary description

Crimp coupling with a threaded nipple, size 16 x 3/4, from SiGMA-Li (model MZPŚ3416). Designed for joining pipes and creating a threaded transition to fittings or valves. Suitable for use in plumbing and heating installations where a permanent, crimped connection to a 16 mm pipe and a 3/4" threaded outlet is required.

## Long description

Crimp Coupling with Threaded Nipple 16 x 3/4 SiGMA-Li MZPŚ3416 is a plumbing fitting designed to create a secure, permanent connection between a 16 mm pipe and a 3/4" threaded outlet. Manufactured by SiGMA-Li, this coupling provides a crimped joint on the pipe side and a standard male thread on the nipple side, allowing transition to valves, taps or other threaded fittings. It is intended for use in potable water and heating systems where reliable mechanical and leak-tight performance is required.
Advantages
The coupling combines a crimp-type connection for quick, consistent installation with a threaded nipple for compatibility with common fittings. Its design reduces the need for soldering or glue, shortening installation time and minimizing on-site preparation. The crimp interface ensures a uniform seal around the 16 mm pipe, while the threaded outlet provides a standard connection point for valves and accessories. Materials and construction are chosen for corrosion resistance and long service life in typical domestic and commercial plumbing applications.
Suitable for
Joining 16 mm plastic or metal pipes to 3/4" threaded fittings
Transition points to valves, taps and meters in domestic water systems
Heating circuit connections requiring a threaded outlet
Applications where a permanent, crimped connection is preferred over compression or soldered joints
Key specifications
Pipe connection size: 16 mm (crimp connection)
Threaded outlet: 3/4" male thread
Type: crimp coupling with threaded nipple
Typical use: plumbing and heating installations
Connection method: permanent crimp on pipe side, threaded on outlet side
How to use
Prepare the 16 mm pipe by cutting squarely and deburring the cut end. Slide the appropriate crimp sleeve or ring over the pipe, insert the pipe fully onto the coupling's crimp end, and position the sleeve according to the manufacturer's marking. Use a compatible crimping tool calibrated for 16 mm fittings to make the crimp connection, ensuring an even and complete deformation of the sleeve. Once the crimp is made, thread the nipple into the receiving fitting or valve using appropriate thread sealant or tape where required, and tighten to the specified torque for the application.
Usage recommendations
Verify compatibility of pipe material with crimp fittings and follow installation guidelines for crimp sleeve selection and crimping tool jaws. Do not overtighten the threaded connection; use recommended sealing methods and test the system for leaks after installation.
