Naldoni e Biondi NBMNTCG1/4 is a short male half nipple in the NBMNTCG cylinder-components family. The current manufacturer catalogue specifies S355J2C steel and shows a male-threaded end with an unthreaded fabrication end. It is grouped as a weldable adaptor rather than a female cylinder oil-port boss.
The exact row gives nominal thread F = 1/4”, overall length C = 18 mm and outside diameter B = 19 mm. The original section includes an internal conical end profile but specifies no seating angle or sealing-interface standard. No 60-degree cone, ISO thread equivalence, pressure rating, flow capacity or welding-assembly rating is inferred.
The complete article is printed in the manufacturer table and appears in the independent supplier's selected manufacturer-article-number field. The selected supplier stock-model row agrees with the exact manufacturer F/C/B dimensions and mass. The supplier brand is blank (--); the offer confirms an observed article designation, not independent authentication of a supplied Naldoni unit.
The genuine supplier photograph is representative of the appropriate short or long half-nipple family and may be shared between sizes. It does not certify the exact dimensions, surface finish or supplied revision. The local technical reference contains the complete original manufacturer page with this exact row and the corresponding short/long section.
