CORTECO 12000519B 48x65x10 NBR BASL Radial Shaft Oil Seal

CORTECO 12000519B 48x65x10 NBR BASL Radial Shaft Oil Seal

CORTECO 12000519B is a radial shaft oil seal with exact dimensions of 48x65x10 mm. It is manufactured from NBR - Nitrile Butadiene Rubber, and the exact CORTECO design designation is BASL.

The seal incorporates an additional dust lip. Its combination of reference, dimensions, material and design provides more precise identification than the generic description "48x65x10 oil seal".

CORTECO 12000519B Technical Specification

Manufacturer: CORTECO

Full reference: 12000519B

Base reference: 12000519

Trade Number: 82000519

Product type: Radial shaft oil seal

Design: BASL

Material: NBR - Nitrile Butadiene Rubber

Dimensions: 48x65x10 mm

Inside diameter d: 48 mm

Outside diameter D: 65 mm

Width B: 10 mm

Additional dust lip: Yes

CORTECO 12000519B Dimensions

The exact dimensions are:

Inside diameter d: 48 mm

Outside diameter D: 65 mm

Width B: 10 mm

Complete dimensions: 48x65x10 mm

The 48 mm dimension corresponds to the nominal shaft diameter, 65 mm to the outside diameter and 10 mm to the seal width.

All three dimensions should be verified together with the NBR material and BASL design when identifying a replacement.

Matching the 48x65x10 mm dimensions alone does not establish complete technical interchangeability.

BASL Oil Seal Design

Exact CORTECO design: BASL

Reference: 12000519B

Dimensions: 48x65x10 mm

Material: NBR

Additional dust lip: Yes

The BASL designation is an important part of the technical identification of CORTECO 12000519B.

CORTECO's dimensional catalogue directly associates reference 12000519B with the combination BASL, 48x65x10 mm and NBR.

Other CORTECO seals with the same 48x65x10 mm dimensions exist with different materials and designs. Therefore, BASL should be considered together with the dimensions and NBR material when selecting a replacement.

Additional Dust Lip

CORTECO 12000519B incorporates an additional dust lip.

The primary lip provides the main sealing function, while the additional lip forms a secondary barrier on the external side of the primary sealing area.

This configuration helps limit the ingress of external contamination toward the main sealing zone.

The presence of the dust lip is confirmed for this exact reference and should be considered when comparing technically similar seals.

NBR - Nitrile Butadiene Rubber

The specified material for CORTECO 12000519B is:

NBR - Nitrile Butadiene Rubber

NBR forms part of the exact product specification together with the 48x65x10 mm dimensions and BASL design.

A 48x65x10 mm seal manufactured from FPM, ACM or another elastomer should not automatically be considered an equivalent replacement.

CORTECO 12000519B Applications

CORTECO 12000519B appears in current application catalogues across several vehicle and drivetrain systems.

Depending on the specific application, it is catalogued in connection with crankshaft, camshaft and transmission-side sealing positions.

Because the same CORTECO reference has multiple application contexts, compatibility should be established using the OE reference and exact vehicle or machine configuration, rather than the generic application name alone.

Base reference: 12000519

Full CORTECO reference: 12000519B

Trade Number: 82000519

These identifiers refer to the same CORTECO product family and provide useful search paths when identifying the exact seal in different catalogues.

For precise product identification, the full reference 12000519B should be preferred.

CORTECO 12000519B and Previous References

Current TecDoc-derived data indicate that CORTECO 12000519B replaces earlier CORTECO references:

12010963B

12011331B

This information can be useful when identifying the seal from older documentation, stock records or markings associated with previous CORTECO references.

The current reference should be verified when replacing an older part.

CORTECO 12000519B vs Standard 48x65x10 Oil Seal

CORTECO 12000519B should not be selected solely as a generic 48x65x10 mm oil seal.

Its confirmed specification includes:

Dimensions: 48x65x10 mm

Material: NBR

Design: BASL

Additional dust lip: Yes

A different 48x65x10 mm oil seal may use another material, lip configuration or sealing design.

For example, CORTECO catalogues contain several different 48x65x10 mm references with different technical configurations. Therefore, identical nominal dimensions do not establish complete interchangeability.

How to Identify a Replacement for CORTECO 12000519B

For accurate replacement selection, verify:

Full reference: 12000519B

Base reference: 12000519

Trade Number: 82000519

Inside diameter: 48 mm

Outside diameter: 65 mm

Width: 10 mm

Material: NBR

Design: BASL

Additional dust lip: Yes

OE reference: According to the specific application

For vehicle-specific use, the relevant OE number and installation position should take priority over dimensional matching alone.

What is the Trade Number for CORTECO 12000519B?

The Trade Number is 82000519.

Does CORTECO 12000519B have a directional twist?

The verified CORTECO dimensional data identify the seal as BASL without an LD, RD or WD directional designation. A Left-hand, Right-hand or Alternating Twist specification should therefore not be added without further exact-product documentation.

Can any 48x65x10 NBR oil seal replace CORTECO 12000519B?

Not automatically. The replacement should also correspond to the required BASL design, dust lip configuration and application-specific OE reference.

Frequently Asked Questions by Engineers

Are CORTECO 12000519 and 12000519B the same reference?

12000519 is the base reference, while 12000519B is the full CORTECO product reference.

Is BASL confirmed for CORTECO 12000519B?

Yes. CORTECO dimensional catalogue data directly specify 12000519B - 48x65x10 - BASL - NBR.

Is CORTECO 12000519B the same as CORTECO 12001177B?

No. Both references have nominal dimensions of 48x65x10 mm and BASL design, but CORTECO catalogue data specify NBR for 12000519B and FPM for 12001177B. They should not automatically be treated as interchangeable.

Why is the complete CORTECO reference important?

CORTECO lists multiple seals with identical nominal dimensions but different materials and sealing designs. The full reference provides substantially more precise identification than dimensions alone.
