Unidelta reducer fitting PE 25 x 20 mm, model 601125

Unidelta reducer fitting PE 25 x 20 mm, model 601125 is a polyethylene compression connector designed to join PE pipes with outer diameters of 25 mm and 20 mm. Intended for low-pressure water distribution, irrigation lines and general plumbing installations, the fitting provides a mechanical transition between two pipe sizes while maintaining a watertight connection when installed on compatible PE tubing.

Advantages

The fitting is made from durable polyethylene that resists corrosion and chemical degradation typical in outdoor and underground installations. Its compression-style design enables a secure joint without solvent welding or heat fusion, simplifying repairs and modifications. The compact reducer shape minimizes flow disturbance at the transition point and is suitable for repetitive assembly and disassembly when maintenance is required.

Suitable for

• Irrigation systems for gardens, greenhouses and small farms
• Low-pressure potable water distribution in residential and commercial settings
• Connecting or adapting sections of PE tubing with 25 mm and 20 mm outer diameters
• Temporary or permanent plumbing runs where mechanical compression fittings are preferred

Key specifications

• Material: polyethylene (PE)
• Connection type: compression reducer for PE tubing
• Compatible outer diameters: 25 mm to 20 mm
• Application pressure range: suitable for low-pressure water and irrigation systems
• Operating environment: indoor, outdoor and buried installations (subject to local installation practices)

How to use

Prepare both pipe ends by cutting squarely and removing burrs or debris. Slide the compression nut and any included sealing components onto the pipe, insert the pipe fully into the fitting until it seats against the internal stop, then tighten the compression nut by hand and finish with a suitable spanner to the manufacturer's recommended torque if available. Verify alignment and perform a pressure test at working pressure to confirm there are no leaks before burying or finalizing the installation.

Usage recommendations

Use the fitting with PE pipes of the specified outer diameters and avoid exceeding the intended low-pressure application. For buried installations protect the connection from sharp rocks and avoid prolonged exposure to strong UV without additional protection. If unsure about system pressure or compatibility with potable water, consult relevant local regulations and installation guidelines.
