Equal Tees for Thermoplastic Branched Pipelines
UNP’s Thermoplastic Equal Tee joins three pipe runs of equal diameter at a single 90° branch — the standard fitting for distribution headers, manifolds, and any branching point in solid-plastic pipelines.
Injection moulded as a single piece with socket-weld ends on all three legs. Same wall thickness as the matching pipe, so the tee maintains the pressure rating of the joined pipe sections through all three legs.
Available in PP, PPH, PVDF, and ISO.PP. For reduced-branch tappings (smaller branch off larger main — e.g., instrumentation, drains), we also supply unequal tees on request.

- ✓Equal-leg 3-way branch fitting
- ✓Socket weld ends on all three legs
- ✓Injection moulded (uniform wall)
- ✓Unequal tee available on request
- ✓PP / PPH / PVDF / ISO.PP materials

Materials of Construction
| Material | Description |
|---|---|
| PP (Polypropylene) | General-purpose, low-cost option for mildly corrosive media at moderate temperatures. |
| PPH (Polypropylene Homopolymer) | Higher mechanical strength than PP — better for pressure service. |
| PVDF (Polyvinylidene Fluoride) | Superior abrasion resistance and high mechanical strength. |
| ISO.PP (Isotactic Polypropylene) | Improved temperature and chemical resistance vs standard PP. |
Connection Types Available
| Connection | Description |
|---|---|
| Socket Weld | Heat-fused socket joints for permanent, leak-tight assemblies. |
| Butt Weld | End-to-end heated fusion for in-line pipe sections. |
| Threaded | Removable threaded fittings for serviceable connections. |
| Flanged | Bolted flange joints for easy disassembly and inspection. |
