Our Expert's Opinion
"Essential for maintaining leak-free hydraulic connections."Vaillant 103415 O-Ring 10 Pack - Genuine Vaillant part
The Vaillant 103415 O-Ring Pack (10 pieces) is a manufacturer-approved replacement item designed for use across a wide range of Vaillant boiler models, particularly those in the ecoTEC Plus, ecoTEC Pro, VU and VUW series. This pack allows you to replace worn or damaged O-rings during routine servicing or repair, ensuring that hydraulic joints — such as heat exchanger connections, pump unions, diverter valve interfaces and other internal fittings — remain sealed and operate as the boiler manufacturer intended. Each O-ring is made to Vaillant’s exact specifications in terms of material composition, hardness, dimensions and tolerance. Using the correct part ensures that sealing surfaces retain their original performance characteristics: resisting pressure, temperature fluctuations and chemical exposure within the boiler’s internal environment. Worn or incorrect O-rings can lead to leaks, loss of system pressure, corrosion inside the boiler housing, or even system shutdowns due to safety triggers — problems that genuine replacements help avoid.
Vaillant provide a 1 year warranty on all genuine spare parts. Electrical Deals Direct now sells a wide range of spare parts. If you cannot see the item you require on our website, please call 01934 253600 or email [email protected] for more information.
