The U-PVC fittings of the plain threaded series have a smooth mouth (for gluing) and a threaded mouth belonging to the GAS – BSP family (Withworth non metric threading, cylindirical with fine pitch).
The metal reinforcement ring inserted in the threaded mouth, fixed with PTFE tape offers a perfect seal, eliminating any play even without clampings which are too tight. The smooth mouth must be glued to fittings and U-PVC pipes with compatible sizes and tolerances.
