De Dietrich 83360507, raccordo in acciaio 55.22, vernice

This steel nipple is a connection fitting from De Dietrich, used to join boiler pipework to the appliance or to its internal components. Parts of this type belong to the category of boiler-specific fittings, adapters and connection sets that link the boiler to the gas, water or condensate lines. The nipple is made of steel with a paint coating, which provides a basic level of corrosion protection. The manufacturer code 83360507 and catalogue article 336.535.001 are the reference numbers for this exact item. When selecting a replacement nipple of this class, the key parameters are thread type and size, material, and sealing method. The thread may be parallel or tapered, and the seal can rely on a flat gasket, an O-ring, or the taper itself. Because the geometry of boiler-specific connection sets is fixed by the appliance design, manufacturer-specific fittings such as this one rarely have generic equivalents. It is essential to verify the thread dimensions and the sealing arrangement against the original part before ordering. This nipple is intended for use in one of the boiler’s pipe circuits – water, gas or condensate – but its exact role depends on the installation. The paint coating is a surface finish; for external pipework, additional sealing compound or tape may be required depending on the thread type. Always confirm that the thread length and orientation match the original fitting to ensure a leak-free assembly.
