Transition compression fitting Unidelta PE GZ 50 mm x 6/4" (601550) for polyethylene pipes

Unidelta transition compression fitting PE GZ 50 mm x 6/4" is a mechanical connector designed to join polyethylene (PE) pipes with a 6/4" threaded male connection. Intended for water supply and irrigation systems, this fitting creates a watertight transition between a smooth PE pipeline and a threaded outlet or component, enabling repairs, extensions and system integration in residential and light commercial installations.

Advantages

The compression design ensures a secure mechanical seal without the need for heat fusion or specialized electrofusion equipment. Constructed for compatibility with standard PE pipe outer diameter of 50 mm, the fitting simplifies installation by using a threaded joint on one side and a compression grip on the other. Its straightforward assembly reduces installation time and allows disassembly for maintenance if required.

Suitable for

• Connecting PE water mains to threaded valves, hydrants or fittings
• Repairing or extending polyethylene pipelines in domestic supply systems
• Irrigation system connections where a PE-to-threaded interface is needed
• Light commercial plumbing applications requiring a reliable transition

Key specifications

• Pipe compatibility: polyethylene (PE) pipes with 50 mm outer diameter
• Thread connection: male threaded 6/4" end for mating with standard threaded components
• Connection type: compression fitting on PE side, threaded on opposite side
• Application: potable water distribution, irrigation and general fluid conveyance
• Installation: mechanical assembly without fusion; removable for maintenance

How to use

Prepare the PE pipe end by cutting squarely and removing burrs or debris. Slide the compression nut and sealing components onto the pipe, insert the pipe fully into the fitting until it reaches the internal stop, and tighten the compression nut to the specified torque to obtain a leak-free seal. Screw the 6/4" male threaded end into the corresponding threaded component using appropriate thread sealant or tape as required by the application. After installation, pressurize the system and inspect the joint for leaks.

Usage recommendations

Use compatible PE pipe dimensions and follow local plumbing codes. Verify material compatibility with transported fluids and avoid overtightening the compression nut to prevent deformation of the pipe. For potable water systems, use approved sealing materials on threaded connections and perform a pressure test after installation.
