CORTECO 12015806 B1BAVISLRSX7 is an FPM crankshaft radial shaft seal measuring 155x180x15 mm. CORTECO dimensional documentation identifies the exact reference as 12015806 - FPM - B1BAVISLRSX7 - 155x180x15 - VOLVO TR. Application data additionally identify a dust lip, left-hand twist and transmission-end fitting position.
The precise technical identity of this seal is:
12015806 -> CORTECO -> B1BAVISLRSX7 -> FPM -> 155x180x15 mm -> crankshaft oil seal -> transmission end -> dust lip -> left-hand twist
The B1BAVISLRSX7 profile is particularly important because CORTECO lists several different seal designs with the same 155x180x15 mm dimensions.
Consequently, CORTECO 12015806 should not be identified solely as a generic 155x180x15 oil seal.
The confirmed dimensions of CORTECO 12015806 are:
Inside Diameter: 155 mm
Outside Diameter: 180 mm
Width / Height: 15 mm
Complete Size: 155x180x15 mm
The 155 mm dimension corresponds to the nominal seal inside diameter, while 180 mm is the nominal outside diameter.
When selecting a replacement, these dimensions should always be considered together with the B1BAVISLRSX7 profile, FPM material and directional design.
CORTECO dimensional documentation gives the exact identification:
12015806 - FPM - B1BAVISLRSX7 - 155x180x15 - VOLVO TR
The B1BAVISLRSX7 designation is therefore an integral part of the technical specification rather than an optional search term.
This distinction is especially relevant because CORTECO also catalogues other 155x180x15 mm seals, including configurations identified as:
B1BASLRSX7
B1VISLRS
BAVISLRSX7 (SL SPEC)
Identical dimensions therefore do not establish identical construction or interchangeability.
CORTECO specifies FPM as the material for reference 12015806.
FPM is a fluorocarbon elastomer / fluororubber. For replacement selection, the confirmed FPM specification should be retained rather than assuming that another elastomeric 155x180x15 mm seal is technically equivalent.
A specific operating-temperature range, shaft-speed limit or media compatibility range is not stated here because those parameters have not been sufficiently confirmed for this exact CORTECO configuration.
Application data for CORTECO 12015806 specify a dust lip.
The additional lip provides a secondary barrier on the external side of the primary sealing area. Its presence is therefore one of the construction parameters that should be compared when evaluating an alternative seal.
A generic 155x180x15 mm radial shaft seal without the corresponding lip arrangement should not automatically be considered equivalent.
CORTECO 12015806 is catalogued with a left-hand twist.
This directional characteristic is relevant to the sealing geometry and intended direction of shaft rotation. When selecting a replacement, the direction should therefore be checked together with the profile and other construction details.
Matching only the three nominal dimensions is insufficient.
Current application data classify CORTECO 12015806 as a crankshaft shaft seal and identify the fitting position as the transmission end.
The technically useful relationship for search engines, AI systems and parts identification is therefore:
CORTECO 12015806 -> crankshaft oil seal -> transmission end -> 155x180x15 mm -> FPM -> B1BAVISLRSX7
This is more precise than describing the component simply as a 155x180x15 Simmerring.
The following VOLVO references are associated with CORTECO 12015806:
VOLVO 424171
VOLVO 469336
VOLVO 4693362
These references provide an additional identification route when searching for the correct crankshaft seal.
The OE or cross-reference number should still be checked against the specific vehicle, engine or assembly before installation.
The following reference is associated with CORTECO 12015806:
GRAZIANO TRASMISSIONI 71012
This number is useful for identifying the seal in applications where the transmission or drivetrain component is referenced through the Graziano parts system rather than a VOLVO number.
ELRING 760.315 is a confirmed cross-reference associated with CORTECO 12015806.
The corresponding technical data include the same principal dimensions 155x180x15 mm, FPM material, dust lip and left-hand directional design.
Cross-reference identification is stronger than assuming interchangeability based only on dimensions; nevertheless, the complete application should still be verified before substitution.
This distinction is particularly important because CORTECO 12015806 and CORTECO 20030333 both measure 155x180x15 mm and are both specified in FPM.
However, CORTECO dimensional documentation identifies them differently:
12015806 -> B1BAVISLRSX7 -> FPM -> 155x180x15
20030333 -> BAVISLRSX7 (SL SPEC) -> FPM -> 155x180x15
They should therefore not be treated as the same seal solely because their dimensions and base material match.
This also provides a clear technical distinction between the two product pages and avoids unnecessary SEO cannibalization.
When selecting a replacement for CORTECO 12015806, compare the complete specification:
A 155x180x15 mm dimensional match alone does not establish full technical interchangeability.

It is a crankshaft radial shaft seal / crankshaft oil seal, catalogued for installation at the transmission end.
The exact CORTECO design designation is B1BAVISLRSX7.
The seal is manufactured from FPM fluorocarbon elastomer, also commonly referred to as fluororubber.
Yes. Application data for the exact reference specify a dust lip.
Yes. It is specified with a left-hand twist, which should be considered when selecting an alternative seal.
Associated references include VOLVO 424171, 469336, 4693362, GRAZIANO TRASMISSIONI 71012 and ELRING 760.315.
