Unidelta PE Pipe Tee 40 mm (model 603040) — polyethylene plumbing fitting

Unidelta PE Pipe Tee 40 mm is a polyethylene plumbing fitting engineered to form a three-way junction in PE piping systems. Designed for pipes with a 40 mm nominal diameter, this tee enables the connection of three matching-diameter polyethylene pipes used in potable water distribution, irrigation networks, drainage runs, or underground conduit installations. The fitting provides a corrosion-resistant, lightweight junction compatible with common fusion and compatible mechanical joining techniques where materials and procedures permit.

Advantages

The polyethylene construction ensures chemical and corrosion resistance and reduces the need for maintenance over time. Its smooth internal surface minimises flow resistance, helping to maintain hydraulic efficiency in supply and irrigation systems. The fitting’s uniform wall thickness and dimensional stability support reliable heat-fusion or approved mechanical connections, while the lightweight material simplifies handling and installation in confined or underground spaces.

Suitable for

• Domestic and municipal water supply lines using PE pipes
• Irrigation systems for agriculture and landscaping
• Subsurface drainage and conduit runs
• Industrial fluid distribution where polyethylene is specified

Key specifications

• Material: polyethylene (PE)
• Nominal diameter: 40 mm
• Configuration: three-way tee for branch connection
• Suitable joining methods: heat fusion and compatible mechanical fittings (subject to compatibility with pipe type and local standards)
• Application environments: buried installations, above-ground pipe runs, irrigation and potable water systems (as permitted by regulations)

How to use

Select matching-diameter polyethylene pipes and prepare pipe ends according to the chosen joining method and applicable standards. For fusion joining, ensure surfaces are clean and use the correct fusion equipment and parameters for 40 mm PE pipe to achieve a uniform, pressure-tight joint. For mechanical connections, use approved couplings and follow manufacturer instructions to secure a reliable seal. After installation, pressure-test the assembled network in accordance with local codes and inspection procedures before commissioning.

Usage recommendations

Confirm material compatibility, pressure rating and local regulations before installation. Use certified fusion equipment or approved mechanical fittings and trained personnel for joining. Protect the fitting from prolonged UV exposure if left above ground, and backfill excavations carefully to avoid point loads on the junction.
