Connector SiGMA-Li ZZ632 GZ 63x2" — pipe coupling connector

SiGMA-Li ZZ632 is a GZ 63x2" pipe coupling connector designed to join two threaded pipes with a nominal diameter of 63 mm and a 2" thread form. Intended for use in water supply and heating systems, this mechanical coupling provides a straightforward method to connect, repair or extend pipeline sections where a threaded joint is required. The product is manufactured for compatibility with standard threaded pipes of the indicated size and is appropriate for both new assembly and in-place repairs.

Advantages

The coupling offers a robust threaded connection that enables reliable mechanical sealing when installed with appropriate sealing materials. Its standardized thread form ensures compatibility with pipes and fittings of the specified nominal size. The design simplifies installation and replacement, reducing the need for specialized tools beyond common wrenches or spanners. The connector is suitable for use in tight spaces and allows for quick disassembly if maintenance or reconfiguration of the piping system is necessary.

Suitable for

• Connecting two threaded pipes with nominal diameter 63 mm and 2" thread form
• Repairing damaged threaded sections in water supply and heating pipelines
• Extending existing threaded piping runs in residential and commercial systems

Key specifications

• Thread form: 2" (as specified in the product name)
• Nominal pipe diameter: 63 mm
• Function: mechanical coupling for threaded pipe connections
• Typical application: water supply and heating installations
• Installation type: threaded joint requiring compatible thread engagement and sealing

How to use

Prepare the pipe ends by cleaning threads and removing debris or old sealing material. Apply an appropriate thread sealant or tape to the male threads according to installer practice and system requirements. Thread the coupling onto the first pipe by hand until engagement, then tighten with a wrench to achieve a secure connection without over-torquing. Align the second pipe and similarly thread it into the opposite side of the coupling, again applying sealing material and tightening to the required fit. After assembly, inspect the joint for correct alignment and perform a pressure or leak test in accordance with local codes and system specifications.

Usage recommendations

Use compatible sealing materials rated for potable water or heating systems as required. Ensure threads match the specified 63 mm / 2" form and that installation torque is controlled to avoid thread damage. For systems under pressure, perform an appropriate leak test after installation and follow applicable standards for potable water or heating installations.
