Transitional PE Threaded Connector Unidelta 25 mm x 1" (601526) - plumbing fitting

Unidelta transitional PE threaded connector 25 mm x 1" is a plumbing fitting created to join 25 mm outside-diameter polyethylene (PE) pipe to standard 1-inch threaded components. The connector provides a mechanical transition that ensures a sealed interface between PE pipe and female or male threaded fittings used in water supply, irrigation systems and general utility connections. Constructed to meet routine potable water and plumbing requirements, the connector is intended for straightforward installation where a reliable PE-to-thread junction is needed.

Advantages

The connector offers a compact design that allows a secure mechanical connection without special tooling beyond common plumbing tools. Its materials resist common water-related corrosion and chemical exposure typical in potable water and irrigation systems. The transitional design reduces the need for additional adaptors and simplifies coupling between flexible PE pipe and rigid threaded valves, meters or fittings. The product supports standard 25 mm PE pipe outer diameter and 1" threaded interfaces to ensure compatibility with widely used plumbing components.

Suitable for

• Connecting 25 mm PE supply lines to 1" threaded valves or taps
• Irrigation main lines joining to threaded distribution fittings
• Domestic potable water service transitions from PE pipe to threaded appliances
• Temporary or permanent utility connections where PE-to-thread transition is required

Key specifications

• PE pipe outer diameter compatibility: 25 mm
• Thread size: 1 inch (standard pipe thread)
• Function: transitional mechanical connector between PE pipe and threaded fittings
• Intended media: potable water and general water distribution
• Typical application: plumbing, irrigation and utility connections

How to use

Prepare the PE pipe by cutting a square, clean end and deburring the pipe bore and outside edge. Insert the pipe fully into the connector’s socket or compression section according to the manufacturer’s alignment marks, then tighten the compression nut or mechanical clamp until secure, ensuring the pipe cannot be pulled out. Thread the 1" threaded end into the mating female or male component using appropriate thread sealant or tape if the mating fitting requires it, and tighten to the recommended torque for the threaded component. After assembly, test the connection under operating pressure to confirm there are no leaks.

Usage recommendations

Use appropriate thread sealant or PTFE tape on threaded joints where required by the mating component. Do not exceed the pressure and temperature limits of the PE pipe or the threaded fitting; consult pipe and fitting specifications for maximum operating conditions. For buried or pressurized installations, perform a pressure test after installation and inspect periodically for mechanical stress or movement of the joint.
