What Is The Difference Between A Reiber And A Non-Reiber Gasket?
Reiber gasket. A steel wire or steel strip insert is incorporated in the gasket, which helps “lock-in” the gasket in the bell ring groove. This gasket is non-removable, and higher insertion forces may be encountered compared to the non-locked-in gasket. Non-Reiber gasket. This non-locked-in gasket is typically pre-installed from our factory. Ensure that the ring groove is clean should this ring be removed and re-installed in the field. Having indicated the above, both gasket designs conform to the same standards (gasket: ASTM F 477, and joint qualification: ASTM D 3139) and installation procedures for our Ring-Tite IPS PVC pipe. Joint preparation and assembly considerations include the following: • Ensure the bell, gasket and spigot are clean prior to and during assembly. • Ensure the gasket is seated evenly in the ring groove. • Apply lubricant evenly and only on the spigot end. Applying lubricant on the gasket may introduce lubricant onto the ring groove, making the ring prone to dis
