Description
This polypropylene 90° tee fitting is used to form a branch connection within metric PP pipe systems, allowing three pipes of equal diameter to be joined at right angles. Manufactured from high heat stabilised PP-B material, it is designed for pressure-rated applications handling aggressive chemicals and elevated operating temperatures.
The tee configuration enables efficient distribution or diversion of flow while maintaining consistent internal geometry. When fusion welded, the fitting forms a continuous, homogenous joint that delivers long-term strength, leak resistance and excellent chemical compatibility across the system.
Unlike metallic alternatives, polypropylene tees are resistant to corrosion, scaling and chemical attack, helping to extend service life and reduce maintenance requirements. The material’s flexibility also allows it to absorb thermal expansion and mechanical stress, supporting reliable performance in demanding industrial installations.
Key Features & Benefits
