CORTECO 12016925B is a radial shaft oil seal manufactured from NBR in the specific BASFX7 design. Its nominal dimensions are 25x37x7 mm.

BASFX7 Design

The manufacturer catalogue identifies BASFX7 as the specific construction code for CORTECO 12016925B. It is important not to replace this designation with the generic TC description: the same CORTECO dimensional range lists BASFX7 and TC as separate designs.

This distinction is particularly important when identifying an existing seal or selecting an exact replacement.

NBR Material

CORTECO specifies NBR for 12016925B. Nitrile rubber is widely used for radial shaft sealing because of its compatibility with many mineral oils and greases. Compatibility with the actual fluid and operating conditions should always be verified before installation.

Correct Identification

For an exact replacement, use the complete identification:

CORTECO -> 12016925B -> BASFX7 -> NBR -> 25x37x7 mm

CORTECO also catalogues other 25x37 mm seals with different widths, materials and designs, so dimensions alone are not sufficient for precise identification.
