Product Overview

The HAWLE Universal Pipe Saddle (No. 3510): Flange is a versatile pipe saddle designed for use with steel, ductile iron, and asbestos cement pipes. It features a compact saddle body with a flanged outlet, and all models are equipped with a double strap for secure installation. The saddle seal is moulded to precisely fit the pipe diameter and is prefixed in the saddle body for ease of assembly. Its design ensures optimum force transfer of the strap screw connection. Flange drilling complies with EN 1092-2 | PN 16, with options for larger nominal diameters on request. All internal threads (if applicable) are fitted with a corrosion protection ring to prevent corrosion and incrustations.
