RIEBERLOK® GASKETSRansom International’s RieberLok® gaskets are the fastest, easiest, and least expensive way of field restraining ANSI/AWWA C900 pipe and fittings originally manufactured with a Rieber gasket. The gaskets are suitable for water, wastewater and other related applications.
To install, simply remove the existing Rieber gasket from the bell socket and insert the RieberLok® gasket in its place. Assemble the joint by following generally accepted procedures for PVC pipe. The joint is now sealed and restrained for working pressures up to the rated pipe pressure.
The gaskets are available in sizes 4"–12". Additional sizes and applications will be available soon. RieberLok® gaskets are NSF61 approved.
There is no need to use bolts, clamps, rods, thrust blocks, or other restraining devices when you can use an easy push-on restraining RieberLok® gasket. RieberLok® gaskets are produced and tested in accordance with the applicable portions of ANSI/AWWA C900.
APPLICATION NOTES1. RieberLok® gaskets are designed to be used in below ground
installations. For other installation environments please contact Ransom International.
2. Do not use RieberLok® gaskets in pipes installed on bridge crossings or in other dynamic environments.
3. Do not reuse previously assembled RieberLok® gaskets as they may have been damaged during the previous installation. RieberLok® gaskets may be removed from the bell socket of a pipe prior to joint assembly and inserted into a different pipe if that is required.
4. For cold weather assembly, maintain the temperature of the gasket above 40º F and assemble the joint as soon as possible after the RieberLok® is inserted into pipe’s bell socket.
5. Ensure that the bell socket, pipe spigot and RieberLok® gasket are clean and free of debris prior to assembly.
6. Ensure that the RieberLok® gasket be properly oriented and seated in the bell socket.
7. Some extension of the joint will occur when pressurized. To minimize this, the joint should be pulled out after assembly to “set” the gasket.
8. When cut pipe are used, the following steps are required:
• Ensure that the spigot end is properly beveled.• Mark the joint depth on the spigot so it is clear when the
joint is fully inserted.• Ensure that the pipe meets the required dimensional
tolerances in the chart below.9. Prior to assembly, ensure that the pipe spigots meet the
required dimensional tolerances shown in the chart below.
