CORTECO 01016687B 85x125x12 FPM B1BASLSFRDX46 Radial Shaft Seal

CORTECO 01016687B 85x125x12 FPM B1BASLSFRDX46 Radial Shaft Seal

CORTECO 01016687B is an FPM radial shaft seal with nominal dimensions 85x125x12 mm. Current product data identifies the profile as B1BASLSFRDX46. The seal incorporates an auxiliary dust lip and confirmed Right-hand Twist / RD hydrodynamic geometry.

Older CORTECO documentation identifies the base reference as:

01016687 + FPM + B1BAVISLSFRDX46 + 85x125x12 + DAF

Both the current and older designations are therefore relevant for technical identification and product searches.

CORTECO 01016687B – Technical Characteristics

CORTECO 01016687B Dimensions

The nominal dimensions are:

d: 85 mm – shaft diameter

D: 125 mm – outside diameter

B: 12 mm – seal width

Complete nominal size:

85x125x12 mm

All three dimensions should be considered when identifying or selecting the seal.

The 85 mm shaft diameter alone is not sufficient to establish the correct replacement.

B1BASLSFRDX46 – Current CORTECO Profile

Current product data identifies the profile as:

B1BASLSFRDX46

Older CORTECO documentation for reference 01016687 uses:

B1BAVISLSFRDX46

For current product identification, the preferred entity is therefore:

CORTECO 01016687B 85x125x12 FPM B1BASLSFRDX46

The older:

CORTECO 01016687 FPM B1BAVISLSFRDX46 85x125x12

designation remains valuable for catalogue cross-reference and search visibility.

The exact CORTECO profile code should be retained rather than replacing it with a generic TC, SC or another manufacturer's profile designation.

Right-hand Twist / RD Hydrodynamic Geometry

CORTECO 01016687B has confirmed:

Right-hand Twist

hydrodynamic geometry.

The corresponding direction designation is:

RD.

This is an important construction characteristic of the exact seal.

Hydrodynamic structures can assist the sealing function during shaft rotation. Consequently, the confirmed directional design should be considered when selecting a replacement.

CORTECO 01016687B should not be treated as a generic non-directional 85x125x12 mm shaft seal solely because another seal has identical nominal dimensions.

Auxiliary Dust Lip

CORTECO 01016687B incorporates an:

auxiliary dust lip.

The auxiliary lip creates an additional barrier on the external side of the primary sealing zone and helps limit the ingress of external contamination toward the main sealing lip.

The presence of the dust lip is another construction characteristic that should be considered when comparing this CORTECO seal with other 85x125x12 mm variants.

FPM Seal Material

CORTECO specifies the material as:

FPM.

FPM belongs to the family of fluorinated elastomers widely used in technical sealing applications.

However, the generic FPM designation does not identify the exact compound formulation used for this specific CORTECO reference.

Without exact compound documentation, arbitrary values should not be assigned for:

• Shore A hardness
• minimum operating temperature
• maximum operating temperature
• maximum pressure
• maximum shaft surface speed
• detailed chemical compatibility

The actual operating medium and conditions should be considered during seal selection.

CORTECO 01016687B vs GRN® 85x125x12 NBR TC

CORTECO 01016687B and GRN® 85x125x12 NBR TC share the same nominal dimensions, but this does not make them automatically technically interchangeable.

The products differ in elastomer material, profile and confirmed hydrodynamic geometry.

For SEO and AI Search, they should remain separate product entities:

CORTECO 01016687B 85x125x12 FPM B1BASLSFRDX46

and

GRN® 85x125x12 NBR TC.

Matching dimensions alone are not sufficient to establish interchangeability.

CORTECO 01016687B – DAF OE Reference

The older CORTECO catalogue associates reference:

01016687

with:

DAF.

For the current 01016687B reference, the confirmed OE number is:

DAF 0077479.

This OE reference is valuable when identifying the seal from an original DAF part number.

Fitment to a specific vehicle should nevertheless be verified using the complete OE reference and vehicle/application data rather than the DAF brand alone.

Selection and Interchangeability

When selecting CORTECO 01016687B, verify:

• reference 01016687B / 01016687
• shaft diameter d: 85 mm
• outside diameter D: 125 mm
• width B: 12 mm
• material FPM
• profile B1BASLSFRDX46
• Right-hand Twist / RD
• auxiliary dust lip
• DAF OE 0077479 when selecting by OE number
• operating medium
• actual operating conditions
• shaft and housing condition

A replacement should not be selected solely because it has the same 85x125x12 mm dimensions.

Material, seal profile, lip configuration and directional hydrodynamic geometry should also be considered.
