## Summary description

SiGMA-Li MZPW2534 is a straight pipe connector for PEX piping systems with a 25 mm outer diameter and a 3/4" female (internal) thread. Designed to join PEX pipes to threaded components or valves, it ensures a secure mechanical and threaded connection. Suitable for potable water and heating installations where PEX is used and threaded appliances or fittings must be attached.

## Long description

SiGMA-Li MZPW2534 25x3/4" female threaded PEX straight connector is designed for joining 25 mm outer-diameter PEX pipes to components with a 3/4" internal thread. The connector provides a combined mechanical and threaded junction that is suitable for potable water and heating systems where PEX piping must be connected to threaded valves, fixtures or appliances. The straight design keeps the flow path aligned and simplifies installation in linear runs.
Advantages
The connector offers a reliable mechanical grip on 25 mm PEX tubing combined with a standard 3/4" female thread for compatibility with commonly used threaded fittings and appliances. Its straight configuration reduces pressure losses across the joint and allows a compact connection in confined spaces. The design is intended for water and heating applications and supports a secure, leak-resistant interface when installed according to recommended procedures.
Suitable for
Connecting 25 mm PEX pipes to 3/4" threaded valves and fixtures
Potable water distribution systems using PEX piping
Domestic and commercial heating systems with PEX loops
Situations requiring a straight inline connection between PEX and threaded components
Key specifications
Connection type: straight connector for PEX to internal thread
PEX pipe outer diameter compatibility: 25 mm
Thread type: 3/4" female (internal) thread
Application: potable water and heating installations
Function: combined mechanical grip and threaded connection for leak-resistant joints
How to use
Prepare the PEX pipe by cutting squarely and removing any burrs. Slide the connector onto the pipe according to the manufacturer's recommended insertion depth, ensuring full engagement of the mechanical grip portion. Thread the mating component into the 3/4" female thread and tighten to the specified torque for the system and fitting type to avoid over-tightening. Verify alignment and, after installation, perform a pressure test of the system to confirm the joint is watertight.
Usage recommendations
Use only with compatible 25 mm PEX piping and with threaded components designed for 3/4" internal threads. Follow local plumbing codes and the installation guidelines for PEX systems, including appropriate use of supports, isolation from dissimilar metals if required, and pressure testing after installation.
