Naldoni e Biondi NBBORSPG1/2 is a steel S355J2C through-port in the NBBORSPG cylinder-parts family. It is a weld-on oil-connection component for hydraulic-cylinder fabrication. The P section shows an axial through passage with a female-threaded entry. B is outside diameter and C overall height. The table also lists A, but the current P drawing does not label A; it is retained only as catalogue dimension A and is not interpreted as bore diameter or thread depth.
The complete article number appears in the manufacturer table and in the independent supplier's selected manufacturer-article-number field. The selected supplier stock-model row agrees with this exact manufacturer thread, dimensions and mass. The supplier brand field is blank (--), so the listing confirms an observed article designation rather than independent authentication of a supplied Naldoni unit.
No working-pressure, flow-capacity, cylinder-load or welding-procedure rating is assigned from this component table. The nominal thread entry does not by itself establish a sealing interface or compatibility with another connection standard.
The genuine supplier photograph is representative of the listed family and may be shared across sizes or P/PL lengths. The local PDF contains the complete relevant manufacturer page, including the exact article row and section drawing. Photograph proportions do not replace the documented dimensions.
