Common UPVC tee sizes in Saudi construction and drainage projects range from 20 to 160 mm, with 50, 110, and 160 mm being the most popular. Match the tee size to both the main and branch pipe diameters, and confirm the joint depth before installation to reduce leaks or weak connections.
Yes, standard UPVC tees handle moderate temperatures and typical household drainage. However, avoid leaving them exposed to direct sunlight for long periods in cities like Riyadh or Jeddah. Buried or wall-mounted installations perform better, so select the correct temperature rating and avoid continuous exposure to hot water.
Standard UPVC tees suit cold drainage water and normal pressure. Heat-resistant tees withstand higher temperatures and are less likely to deform or soften in sunny areas. If the fitting is near a heat source or partially exposed, choosing a heat-resistant option improves durability and extends its life inside Saudi buildings.
Choose the tee based on the main pipe diameter and the branch outlet size. For example, use a 50 mm main with a 20 mm branch if that is your system. At Matkel, match the tee to the pipe before purchase and check joint depth to reduce leaks and keep sanitary drainage stable.
It is not recommended. UPVC drainage joints need a proper seal to prevent leaks over time. Use a compatible UPVC solvent cement, clean the surfaces, assemble the fitting, and allow the joint to cure fully. This method meets Saudi building practice and lowers the risk of separation.
