A rubber joint KXT-A PN16 absorbs vibration and small movement at pumps and water pipework.
Its flanged ends bolt into PN16 lines. As a result, pump noise stays out of the building.
What is a rubber joint KXT-A PN16?
A rubber expansion joint, such as the KXT type, is a flexible flanged joint with a rubber sphere between two flanges. It absorbs vibration, noise and small movement in water pipework.
Fitted at pump suction and delivery, it stops pump vibration reaching the building. In addition, it takes up small misalignment during installation.
