We recommend measuring the OD of A/C pipe at the exact location where the fitting is to be installed regardless of the fitting type (i.e., coupling, tapping sleeve, saddle, etc).

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 the entire gasket surface with a potable, NSF certified lube (we recommend 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.

No, we recommend using a Robar coupling to join two plain end pipes together, not for connecting two pipes together.

The Robar #5606 has a full wrap around gasket while the 5696 has a partial gasket that can be used to repair small punctures and pinholes.

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.

All Robar couplings follow AWWA C-219 requirements, which govern the amount of deflection each coupling should accommodate. If you have any questions regarding this standard, contact Robar sales.

A Stainless Steel Tapping Sleeve (#6606) is generally used for “Hot Taps“, and a Stainless Steel Outlet Sleeve (#6626) is for “Dry Taps” only.

Definitely not. Both of these products are too rigid for PVC Pipe and are intended solely for rigid pipe such as Ductile Iron.

No, that gasket is in the box solely to protect the epoxy coating of the tapping sleeve during shipping.
