When installing Robar service saddles, repair clamps and tapping sleeves, be sure there’s no foreign debris (pebbles or dirt) on the gasket or pipe before lubricating. Lubricate with a certified potable lube such as Robar’s SLIKSTYX
We recommend using a clamp that goes at least 5″ beyond the end of the hole/break on each side of the damage to ensure the leak can be stopped. We recommend more than 5” of clamp coverage if there’s a potential for further pipe deterioration around the repair.
Always be sure that there is no foreign debris between the gasket and center ring and then make sure your pipe fits within the working range of the coupling. Also, be sure the gaskets are well lubricated and that you torque each bolt to 80 ft-lbs in a star pattern when tightening.
