## Long description

The Unidelta PE to Female Thread Transition Fitting, with a 50 mm diameter and 5/4" female thread, is a high-performance compression component engineered for seamless integration between polyethylene pipes and threaded system elements. This fitting provides a robust and reliable connection, essential for maintaining integrity in pressurized water distribution networks. Its design prioritizes durability and ease of assembly, making it a preferred choice for both professional plumbing installations and large-scale agricultural irrigation systems.
Advantages
This transition fitting stands out due to its superior build quality and resistance to environmental stressors. The compression mechanism ensures a tight, leak-proof seal without the need for specialized welding equipment, significantly reducing installation time and labor costs.

The precision-engineered threads allow for a secure fit with standard 5/4" components, providing consistent reliability across various water management applications.
Suitable for
Connecting PE pipes to threaded valves or pumps
Agricultural irrigation and water distribution networks
Professional plumbing and municipal water supply systems
Industrial fluid transport lines
When it may not be suitable
This fitting is specifically designed for use with polyethylene pipes and may not be compatible with other pipe materials such as copper, steel, or PVC. It is not intended for high-temperature applications exceeding the thermal limits of standard PE piping systems.
Key specifications
Pipe diameter: 50 mm
Thread size: 5/4" female
Connection type: Compression to threaded
Material: High-quality polyethylene and reinforced components
Application: Water supply and irrigation
How to use
To install the fitting, ensure the PE pipe end is cut cleanly and deburred to prevent damage to the internal O-ring. Loosen the nut on the compression side, insert the pipe fully into the fitting until it reaches the internal stop, and then tighten the nut firmly by hand or with a suitable wrench. For the threaded side, apply appropriate thread sealant or PTFE tape to the male component before screwing it into the 5/4" female thread of the fitting to ensure a watertight seal.
What to consider before purchase
Verify the outer diameter of your PE pipe matches the 50 mm specification
Ensure the mating component features a standard 5/4" male thread
Check the maximum pressure rating of your system against the fitting specifications
Usage recommendations
Always ensure the pipe is inserted straight into the fitting to avoid misalignment, and avoid overtightening the compression nut, as this can damage the internal sealing components.
