Transition fitting Unidelta PE male thread 25 mm x 3/4" 601525

Unidelta transition fitting PE male thread 25 mm x 3/4" is a polyethylene adapter designed to join 25 mm PE pipes to devices or plumbing fixtures with a 3/4" female threaded connection. The fitting creates a reliable threaded junction for low-pressure water distribution, irrigation lines and general fluid conveyance where a PE-to-thread transition is required. It is intended for use in water supply and garden irrigation systems and for simple plumbing connections involving flexible polyethylene piping.

Advantages

The transition fitting offers a corrosion-resistant polyethylene body and a precisely formed male thread that ensures tight engagement with standard 3/4" female fittings. Its compact design simplifies installation on buried or exposed PE pipe runs, while the smooth internal passage reduces flow disruption and pressure loss. The material choice and construction make it suitable for use in potable and non-potable applications where chemical compatibility with PE is required.

Suitable for

• Connecting 25 mm polyethylene pipes to 3/4" threaded valves, taps or appliances
• Garden irrigation systems and dripline connections
• Low-pressure water distribution and outdoor plumbing fixtures
• Temporary or permanent connections where a PE-to-thread interface is needed

Key specifications

• Connection A: socket for 25 mm polyethylene pipe
• Connection B: external male thread 3/4" (compatible with standard 3/4" female fittings)
• Material: polyethylene body with integrally moulded thread
• Application: water supply, irrigation and general fluid distribution at low to moderate pressure
• Operating environment: suitable for buried or exposed installations and outdoor use

How to use

Prepare the 25 mm PE pipe by cutting squarely and deburring the end. Insert the prepared pipe into the socket end of the fitting until it reaches the internal stop; depending on system practice, secure the joint by appropriate mechanical compression, electrofusion or compatible joining method for PE piping. Thread the male 3/4" end into the mating female threaded inlet, applying suitable thread sealant or tape if required by the application to ensure a watertight seal. Check alignment and hand-tighten before applying final torque with appropriate tools to avoid over-tightening.

Usage recommendations

Use this transition fitting in systems designed for the pressure and temperature range of polyethylene piping. Verify compatibility of any thread sealant with polyethylene and the fluid being conveyed. For buried installations, protect exposed threaded connections with appropriate tape or protective cover to prevent ingress of debris and to maintain serviceability.
