Vaillant Sealing Ring Kit Flow/Return 0020058895

The Vaillant sealing ring kit for flow and return connections is a set of sealing rings used to seal the flow and return pipework on Vaillant ecoCRAFT VKK series boilers. The kit contains two flow sealing rings and two return sealing rings. It is designed to prevent leaks at the boiler's flow and return connections.

• Water weeping or dripping from the flow or return pipe connections
• Visible cracks, flattening or hardening of the sealing rings
• Persistent pressure loss in the heating system
• Corrosion or mineral build-up around the connection points
• Joints that require repeated tightening to stop leaks

• Check your boiler model against the fit list to confirm compatibility
• Verify that the leak is at the flow or return connection, not elsewhere
• Confirm the part number 0020058895 matches your requirement
• Note that the kit provides two of each sealing ring, so check if you need both flow and return seals
