## Summary description

Straight connector SiGMA-Li MZPZ321 designed for use with PEX piping systems. Dimensioned 32x1 with a GZ (male) thread, this fitting enables secure mechanical connection between PEX pipes and threaded components. Suitable for plumbing and heating installations where durable pipe-to-thread transitions are required.

## Long description

The SiGMA-Li Connector straight MZPZ321 32x1 GZ for PEX pipes is a straight metallic fitting designed to join PEX tubing with threaded components. Sized for 32 mm PEX pipe with a 1 mm wall allowance and a male (GZ) thread, this connector provides a direct, axial transition between flexible plastic piping and screw-in fixtures or valves used in plumbing and heating systems. The design focuses on a compact in-line connection that maintains flow profile and enables secure mechanical attachment where a threaded termination is required.
Advantages
This straight connector offers a reliable mechanical connection suitable for repeated assembly and disassembly without compromising the PEX line integrity. Its straight geometry minimises pressure drop and simplifies installation in linear runs. Constructed to provide a firm threaded interface, the fitting reduces the need for additional adapters when connecting to standard male-threaded valves and components in residential and light-commercial installations.
Suitable for
 Joining 32 mm PEX pipes to male-threaded valves and fixtures
 Plumbing systems in residential buildings
 Hot and cold water distribution and heating circuits
 Applications requiring compact, in-line threaded transitions
Key specifications
 Connection type: straight connector for PEX to male thread
 Pipe compatibility: PEX pipes with 32 mm outer diameter
 Thread type: male (external) thread with 1 mm pitch specification
 Orientation: axial/straight inline connection
 Typical applications: potable water, heating circuits, service connections
How to use
Prepare the PEX pipe by cutting it squarely and removing any burrs. Slide the connector into the pipe end according to the fitting's insertion depth and secure it using the appropriate crimping or compression method specified for the PEX system in use. Once the pipe is fixed on the connector, thread the male end into the mating female component and tighten to the recommended torque for the threaded joint, using suitable sealant or tape if required by the installation practice. Follow local plumbing codes and the PEX system manufacturer's instructions throughout the process.
Usage recommendations
Use this connector in installations that match the specified pipe diameter and thread type. Confirm material compatibility and temperature/pressure limits of the whole system. For long-term reliability, avoid overtightening the threaded joint and perform a pressure test after installation to verify leak-free connections.
