## Summary description

Unidelta transition fitting (model 601549) is a polyethylene (PE) connector with a 50 mm body and a 5/4" (1¼") male thread.

Designed for mechanical connection where a PE pipe must be adapted to female threaded fittings.

## Long description

Unidelta PE transition fitting model 601549 is a polyethylene connector designed to join a 50 mm PE pipe to a component with a 5/4" (1¼") female thread. The fitting provides a mechanical, watertight junction suitable for water distribution, irrigation systems and general outdoor plumbing where a durable adaptation between smooth PE tubing and threaded equipment is required.
Advantages
The fitting is made from corrosion-resistant polyethylene, offering chemical stability and long service life in buried or exposed installations. Its male threaded end ensures compatibility with standard 1¼" female threads while the socket side is sized for a 50 mm PE pipe, allowing straightforward mechanical or electrofusion-based connections. The design reduces the need for additional adapters and simplifies transitions between plastic piping and threaded valves or appliances.
Suitable for
 Domestic and municipal water distribution networks
 Irrigation systems for gardens, parks and agriculture
 Outdoor plumbing connections to valves, hydrants and appliances with 1¼" female threads
 Buried or above-ground PE piping installations requiring threaded interfaces
Key specifications
 Material: polyethylene (PE)
 Pipe connection size: 50 mm socket
 Thread type and size: male 5/4" (1¼")
 Application: potable and non-potable water distribution, irrigation, outdoor plumbing
 Environment: suitable for buried and exposed installations; resistant to corrosion
How to use
Prepare the 50 mm PE pipe by cutting a clean, square end and ensuring the pipe bore is free of debris. Connect the pipe to the socket according to the chosen method (mechanical clamp, electrofusion or recommended joining practice for the system). Ensure the male threaded end is engaged into the corresponding female thread with appropriate sealing (for example PTFE tape or thread sealant) to achieve a watertight joint. Tighten to the torque recommended for the mating component to avoid over-stressing the fitting or thread.
Usage recommendations
Verify compatibility of the mating female thread and the installation pressure rating before use. Avoid excessive axial loads or bending at the transition point; provide support and correct alignment for the PE pipe to maintain a reliable seal and long-term performance.
