Stormwater Threaded Coupling 90mm joins two lengths of pipe like a plain coupling. It also has a male external thread around one socket end for a matching threaded access cap.
Both 90mm female sockets fit over pipe with an approximately 90mm outside diameter. The access cap screws onto the external thread and can be unscrewed and refitted when access is required.
The pipe sockets are joined using PVC priming fluid and suitable non-pressure PVC solvent cement. The threaded cap connection remains removable.
Suitable for non-pressure PVC stormwater and surface-water drainage systems.
