B1BASL Simmerring Design

CORTECO identifies the seal design as:

B1BASL Simmerring

This configuration incorporates an additional dust lip that forms a secondary barrier on the external side of the primary sealing area.

The dust lip helps reduce the ingress of dust, dirt and other external contaminants toward the primary sealing interface.

When selecting a replacement, the B1BASL design should therefore be considered together with the dimensions and material.

NBR - Nitrile Butadiene Rubber

CORTECO 12016930B is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is widely used for radial shaft oil seals and is compatible with many commonly used mineral oils, lubricating greases and industrial lubricants.

Actual compatibility should always be verified against the specific medium, additives, temperature and operating conditions.

CORTECO 12016930B - Mercedes-Benz OE

The confirmed Mercedes-Benz OE cross-reference for this CORTECO oil seal is:

Mercedes-Benz 0199974747

also written as:

Mercedes-Benz A 019 997 47 47

The OE number provides an important additional identification point when matching the seal to a specific Mercedes-Benz assembly.

Compatibility with the exact vehicle or assembly should be confirmed using the OE number before installation.

12016930B vs 12016930

The seal may also be found under the reference:

12016930

The current CORTECO reference used in replacement-parts catalogues is:

12016930B

The key identification parameters remain:

100x130x13 mm
NBR
B1BASL Simmerring
Trade Number 82016930
Mercedes-Benz OE 0199974747

Using these parameters together helps prevent confusion with other CORTECO radial shaft oil seals of similar dimensions.

Why Is the B1BASL Design Important?

Dimensions alone do not completely identify a radial shaft oil seal.

Different seals can share the same 100x130x13 mm dimensions while differing in:

sealing-lip configuration
elastomer material
external construction
OE application

For CORTECO 12016930B, the important identification is:

100x130x13 mm + NBR + B1BASL + 12016930B

Therefore, dimensional compatibility alone should not be considered proof of full interchangeability.

How to Select CORTECO 12016930B

For correct identification, verify:

Part Number: 12016930B
Trade Number: 82016930
Dimensions: 100x130x13 mm
Material: NBR
Design: B1BASL Simmerring
Dust Lip: Yes
Mercedes-Benz OE: 0199974747 / A 019 997 47 47

The complete part number and OE reference should take priority over dimensions alone when confirming the correct replacement.
