Alkotest connector GZ FI40 x 1.1/4 (model ZZ4054) for pipe joint

Alkotest ZZ4054 is a GZ threaded connector designed as FI40 x 1.1/4 for forming a reliable pipe joint. This single mechanical fitting joins pipes with a nominal diameter of 40 mm using a 1.1/4 inch thread pitch. The connector is intended for installation and repair environments where a threaded coupling is required to provide a sealed and mechanically stable connection between compatible pipe elements.

Advantages

The connector provides a compact solution for threaded pipe connections, offering dimensional compatibility for 40 mm nominal pipes and a standard 1.1/4" thread pitch. Its simple mechanical design enables straightforward assembly and disassembly with common tools. The part reduces the need for welding or adhesive joining methods and allows for quicker maintenance or replacement of sections in a piping system.

Suitable for

• Repair and replacement of threaded pipe sections with 40 mm nominal diameter
• Installation of new piping runs requiring a 1.1/4" threaded coupling
• Applications where mechanical threaded joints are preferred over welded or glued connections
• Plumbing, light industrial, and utility pipe assemblies compatible with GZ-type connectors

Key specifications

• Connector type: GZ threaded connector
• Nominal pipe diameter compatibility: 40 mm
• Thread pitch/size: 1.1/4 inch
• Function: single mechanical fitting for joining pipes
• Installation method: threaded coupling requiring appropriate wrenches or hand tools

How to use

Verify that the pipes to be joined match the connector's nominal diameter and thread size. Prepare the pipe ends by cleaning threads and removing debris or burrs. Apply any required thread sealant or tape according to the system's sealing practice. Thread the connector onto the pipe end by hand to start, then tighten with suitable wrenches to the recommended torque for the pipe material and thread size, avoiding over-tightening. Inspect the joint for alignment and leaks after assembly and perform pressure or leak tests as needed for the application.

Usage recommendations

Use the connector only with compatible pipe materials and matching thread profiles. Follow standard installation practices, apply appropriate thread sealants where required, and verify mechanical compatibility before use. For high-pressure or safety-critical systems, consult applicable codes or a qualified installer to confirm suitability.
