Transition coupling Unidelta PE male-thread 32 mm x 5/4" for polyethylene pipes (mpn 601533)

Unidelta transition coupling PE male-thread 32 mm x 5/4" is a pipe fitting engineered to connect 32 mm polyethylene (PE) pipes with a 5/4" external threaded interface. The coupling provides a mechanical and hydraulic junction between flexible PE piping and standard threaded components, enabling integration of PE distribution lines with valves, hydrants or metal fittings that use a 5/4" thread.

Advantages

This transition coupling is manufactured to ensure reliable sealing and mechanical strength under typical water supply and irrigation pressures. The design simplifies installation by offering a direct push-fit or clamp connection to the PE pipe combined with a standard male thread, reducing the need for additional adapters. Materials and construction are selected for corrosion resistance and long service life in buried or exposed installations.

Suitable for

• Joining 32 mm PE pipes to 5/4" threaded valves and fittings
• Irrigation systems and garden watering networks
• Small-scale water supply lines and service connections
• Temporary or permanent connections between plastic piping and metal threaded components

Key specifications

• Pipe connection: for 32 mm polyethylene (PE) pipe
• Thread type: external male thread sized 5/4"
• Function: mechanical transition between PE pipe and threaded fittings
• Typical application pressure range: suitable for standard water supply and irrigation pressures (refer to system specifications for exact limits)
• Material properties: corrosion-resistant construction suitable for buried and above-ground use

How to use

Prepare the 32 mm PE pipe by cutting square and deburring the end. Insert the pipe into the coupling according to the manufacturer's assembly method — depending on the specific coupling design this may be a push-fit, compression or clamped connection — and ensure the joint is fully seated. Tighten the male thread into the receiving female threaded component by hand and finish with an appropriate wrench if required, taking care not to over-torque. Verify alignment and perform a pressure test of the assembled line according to local installation standards.

Usage recommendations

Use compatible 32 mm PE piping and standard 5/4" female threaded fittings. Follow installation torque limits and perform pressure testing after assembly. For buried installations, apply appropriate bedding and protection to avoid point loads on the coupling. For specific system pressures and temperature ranges consult the overall piping system documentation.
