Product information

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.
