Ariston 65116403 dielectric junction is a genuine replacement insulating connector designed for compatible Ariston hot water cylinders and heating systems. It separates dissimilar metals within the plumbing connection to help prevent galvanic corrosion and extend the service life of the appliance.
Dielectric junctions are essential components in unvented cylinders and water heaters where copper, brass, and steel connections meet. Without proper insulation, electrochemical reactions can cause corrosion, leading to leaks and premature component failure. Over time, the junction may become damaged or degraded during servicing. Replacing it with a genuine Ariston part ensures correct electrical isolation, maintains system integrity, and helps protect the cylinder and associated pipework from corrosion.

We partner with several of the best UK carriers (such as TNT, Royal Mail, DPD etc) depending on the type of product and the warehouse it is coming from, and also with some pallet companies for larger items. All of these operate during normal Monday – Friday working hours, and we expect all deliveries to arrive in 5 days. For more details checkout this page.
For all Gledhill Cylinders, a flat delivery charge of £33.00 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
