Product information

Description

Straight connector SiGMA-Li MZPW1634 16x3/4" Female Thread PEX is a straight transition fitting designed to connect 16 mm PEX tubing to a 3/4" female threaded component. It provides a mechanical interface between flexible PEX pipe and standard threaded valves, adapters or fixtures, enabling a reliable connection in domestic and light commercial plumbing installations where a change from push-fit or PEX piping to threaded hardware is required.

Advantages

The fitting offers a compact straight design that minimizes space requirements and aligns piping runs for straightforward installation. Constructed to be compatible with 16 mm PEX systems and standard 3/4" female threads, it simplifies the transition without additional adapters. The connector is suitable for installations where a secure, pressure-resistant joint between PEX and threaded fittings is needed, reducing the risk of leaks when installed properly.

Suitable for

  • Connecting 16 mm PEX tubing to 3/4" threaded valves or fixtures
  • Domestic plumbing repairs and upgrades involving PEX systems
  • Light commercial piping where PEX meets threaded components
  • Transitions between flexible piping and rigid threaded fittings

Key specifications

  • Connection type: straight connector for PEX to 3/4" female thread
  • PEX tube size compatibility: 16 mm
  • Thread type: 3/4" female (internal) thread suitable for standard threaded fittings
  • Application: potable water and heating circuits in domestic and light commercial settings
  • Orientation: inline/straight coupling

How to use

Prepare the 16 mm PEX tubing by cutting it square and ensuring the tube end is clean and free of burrs. Insert the PEX end into the connector according to the manufacturer's PEX insertion depth recommendations and secure it using the specified crimp, clamp, or compression method compatible with the connector design. Thread the 3/4" female end onto the corresponding male threaded fitting or valve, applying appropriate thread sealant or tape where required by local plumbing practice. Tighten to a firm hand and wrench fit without over-torquing, and verify alignment for a straight, leak-free connection.

Usage recommendations

Use with compatible 16 mm PEX systems and matched installation tools and fittings. Follow local plumbing codes and the PEX system manufacturer's instructions for pressure and temperature limits. Perform a pressure test after installation to confirm joint integrity.
