## Summary description

Crimped pipe fitting with threaded nipple, size 20 x 3/4, by SiGMA-Li (model MZPŚ3420). Designed for creating secure connections between PEX or metal-plastic pipes and threaded components. Provides a press-type mechanical joint with integrated nipple for plumbing installations, heating circuits and domestic water systems where a reliable threaded outlet is needed.

## Long description

Crimped fitting with nipple 20 x 3/4 SiGMA-Li MZPŚ3420 is a press-type pipe fitting designed to join PEX or metal-plastic (multilayer) pipes to a threaded component. The fitting integrates a crimp sleeve and a 3/4" male threaded nipple to provide a secure mechanical connection for plumbing installations, heating circuits and domestic water systems where a threaded outlet is required. Materials and dimensions are chosen to ensure a leak-resistant transition between flexible pipe systems and standard threaded fixtures.
Advantages
The crimped fitting provides a stable mechanical connection without soldering or adhesives, enabling quick installation with standard pressing tools. The integrated 3/4" nipple saves an extra connector and reduces potential leak points by combining the press joint and threaded outlet in a single part. Compatibility with PEX and metal-plastic pipes makes the fitting versatile for potable water and heating applications, and the press connection ensures consistent compression and sealing performance when installed according to recommended procedures.
Suitable for
 Connecting PEX or metal-plastic pipes to 3/4" threaded valves, taps or radiators
 Domestic cold and hot water distribution systems
 Heating circuits and radiator connections
 Renovation projects where replacing multiple fittings with a single combined part is desirable
Key specifications
 Pipe connection size: 20 mm
 Threaded outlet: 3/4" male
 Connection type: crimp/press mechanical joint with integrated nipple
 Compatible pipe types: PEX and metal-plastic (multilayer) pipes
 Typical applications: potable water and heating systems
How to use
Cut the pipe squarely and remove any burrs or sharp edges. Slide the appropriate crimp sleeve over the pipe, insert the fitting fully until the pipe reaches the stop, then position the sleeve correctly over the fitting. Use a compatible pressing/crimping tool and jaw sized for 20 mm connections to make a uniform press around the sleeve. After pressing, confirm the mechanical joint by inspecting the press mark and verifying correct alignment. Once the press connection is made, thread the 3/4" nipple into the mating threaded component using appropriate sealing methods for the thread type, such as PTFE tape or thread sealant, where required by the installation standard.
Usage recommendations
Ensure the pressing tool and jaws match the fitting and sleeve dimensions and are maintained according to the tool manufacturer's guidelines. Follow local plumbing codes regarding thread sealing and system pressure testing; perform a pressure test of the assembled system after installation to confirm leak-tight performance before commissioning.
