Joint Procedure
Pre-Lubricated Gaskets

Step One

Pre-lubricated gaskets are installed on the spigot of the box prior to delivery. Clean all dirt and foreign objects off the bell and spigot. Ensure both the bell and spigot are free of cracks, chips and defects.

Step Two

Align the spigot with the bell. Ensure the gasket is in contact with the entire circumference of both the bell taper and the spigot before fully homing the joint.

Step Three

Engage the spigot into the bell to fully install, locking the joint into place. The self lubricating gasket will roll over the step of the spigot and into the joint recess creating the complete seal.
