Alkotest ZZ321 pipe connector GZ FI32x1 – threaded coupling for 32 mm pipes

Alkotest ZZ321 pipe connector GZ FI32x1 is a threaded coupling designed to join 32 mm pipes using a male/female screw connection. Intended for plumbing and utility piping systems, the coupling provides a secure mechanical joint for water and non-aggressive fluid conveyance. The threaded design allows quick on-site assembly and straightforward repairs without special tools.

Advantages

The Alkotest ZZ321 coupling offers a standardised 32 mm connection with a 1"-equivalent thread form, enabling compatibility with commonly used pipes and fittings. Its screw-type male/female interface provides reliable mechanical retention and simplifies disassembly for maintenance. The compact shape and threaded assembly make it suitable for confined spaces and field repairs where welding or solvent joining is impractical.

Suitable for

• Plumbing installations for water distribution and supply lines
• On-site assembly and repair of utility piping
• Temporary or permanent mechanical connections of 32 mm pipelines
• Application in residential and light commercial pipe systems

Key specifications

• Connection type: male/female threaded coupling
• Pipe diameter compatibility: 32 mm
• Thread form: 1"-equivalent (FI32x1)
• Application: mechanical joining for water and utility piping
• Installation: screw-type assembly for on-site fitting and repair

How to use

Ensure pipe ends are clean, free of burrs and the correct 32 mm outside diameter before fitting. Engage the male and female threads by hand to start, then tighten using appropriate wrenches to achieve a secure mechanical joint without over-torquing. Verify alignment of the pipeline and check for leaks after pressurising the system. For repairs, disassemble by reversing the threaded connection, replace any worn sealing element if present, and reassemble following the same steps.

Usage recommendations

Use thread sealant or appropriate sealing tape where required by the installation standard or local practice to improve leak resistance. Avoid excessive tightening to prevent thread damage. Confirm compatibility of the coupling material with the conveyed medium and operating temperatures before prolonged use.
