Product Overview

The HAKU Tapping Saddle with Inner Thread (No. 5250) is designed for PE pipes according to EN 12201 and DIN 8074, and PVC pipes according to EN ISO 1452-2. It features a HAKU seal that is in full contact with the entire diameter of the pipe and is glued onto the saddle for ease of assembly. Several concentric seals with increasing diameter surround the outlet, relieving pressure exerted upon the drill hole and protecting it from deformation. This saddle is suitable for drilling without pressure. Hawle products with internal threads, including this saddle, are equipped with an anti-corrosion ring to prevent corrosion.
