Reducer Tee Unidelta PE female thread 40 mm x 1" x 40 mm, model 603639

Unidelta Reducer Tee PE with a female 1" threaded branch delivers a compact, corrosion-resistant connection for polyethylene pipeline systems. Designed to join two 40 mm PE pipes while providing a central threaded branch for a 1" fitting, this reducer tee is suitable for water distribution, irrigation and other low-pressure fluid systems. The body is manufactured in polyethylene for chemical resistance and durability in buried or exposed installations.

Advantages

The reducer tee provides a reliable transition between 40 mm PE pipe and a 1" threaded component without the need for additional adapters. Its polyethylene construction ensures resistance to corrosion and many common chemicals, while the integrated female thread allows secure mechanical connection to standard 1" fittings. The compact shape reduces space requirements in manifolds and branching points and simplifies installation and maintenance.

Suitable for

• Drip and sprinkler irrigation networks
• Domestic and small commercial water distribution
• Low-pressure fluid lines for agriculture and landscape watering
• Systems requiring a threaded branch for valves, filters or gauges

Key specifications

• Material: polyethylene (PE)
• Pipe connections: two ends for 40 mm PE pipe
• Branch connection: female threaded 1"
• Function: reducer tee for branching and size transition
• Application pressure: suitable for low-pressure distribution systems

How to use

Prepare the 40 mm PE pipe ends by cutting them square and removing any burrs. Insert the pipe ends into the tee according to the chosen joining method for PE (electrofusion, butt fusion or mechanical compression, depending on product variant and local practice). Screw the 1" male fitting into the central female thread and apply appropriate sealing tape or sealant if required by the fitting manufacturer. Verify alignment and perform a pressure test at operating pressure before final burying or commissioning.

Usage recommendations

Use compatible joining methods and fittings rated for the intended application. Avoid exceeding recommended operating pressures and protect the tee from prolonged exposure to direct sunlight where relevant. When used in buried installations, ensure proper backfill and avoid sharp stones or heavy loads directly above the fitting. Follow local codes and best practices for polyethylene pipe installation and pressure testing.
