HDPE Eccentric & Invert Tees

HDPE Eccentric Tees and Invert Tees are engineered for drainage, sewerage, wastewater, and industrial pipeline systems where maintaining a continuous pipe invert is essential.

By aligning the branch connection with the pipe’s internal bottom level, these specialist HDPE tee fittings promote smoother flow, reduce turbulence, and help prevent solids and sediment from collecting at the junction.
Machined from premium HDPE solid rod or hollow bar, our eccentric and invert tees provide a robust alternative to conventional injection-moulded fittings.

They offer excellent resistance to corrosion, abrasion, chemicals, and environmental stress cracking, making them suitable for demanding underground and above-ground installations.
Available in custom configurations from OD110 mm to OD1600 mm, with SDR7.4 to SDR17 options, every HDPE eccentric tee can be tailored to the project’s pipe diameter, pressure class, branch angle, and connection requirements. Smooth internal surfaces support efficient conveying performance and reduce maintenance demands in gravity and pressurised drainage networks.

Whether used in municipal sewer systems, wastewater treatment plants, industrial effluent lines, mining operations, or drainage infrastructure, our HDPE invert tees deliver durable, leak-resistant, and flow-optimised connections for long service life.
