It seals the pipe connection but will not prevent the pipes from pulling apart under pressure or movement. The pipeline must be securely anchored and supported to prevent axial separation. Question?What types of pipes is the STRAUB-OPEN-FLEX 1L suitable for? It is suitable for all types of metal and plastic pipes, including steel, stainless steel, cast iron, copper, PVC, and PE, as long as the outer diameter matches the coupling’s specification (60.3 mm). Question?What is the recommended bolt torque for the Art. Nr. 35151? The label clearly indicates a required tightening torque of 7.5 Nm (5.5 lbf.ft). It is crucial to use a torque wrench to ensure a proper and safe seal without over-tightening. profideals is not an authorized distributor, reseller, or representative of the products featured on this website.
