About this product
When air dryer cartridge compressed air system performance matters, the FILTRON AD 785/1 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Height [mm]: 174 mm, Thread Size: G 1 1/4, Outer Diameter [mm]: 140 mm, Filter type: 53, Gasket inside diameter [mm]: 99 mm. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 0 986 628 252, 126.096-00A, 126.096-10A, 1.31876 and 52 more. Matching these numbers confirms a like-for-like replacement with no loss of function.

All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops.
