The dimensions 45x72x8 mm are confirmed in CORTECO catalogues for reference 12001700 / 12001700B.
CORTECO 12001700 is manufactured from NBR - nitrile butadiene rubber.
NBR is one of the most widely used elastomers for radial shaft seals. It provides good resistance to many mineral oils and greases and is therefore commonly used in machinery, gearboxes, mechanical systems and agricultural equipment.
Material suitability should always be verified against the actual operating medium, temperature, shaft speed and application conditions.
The CORTECO catalogue specifies the seal design as:
B1KL
The B1KL profile is an important part of the complete product identification.
Correct specification:
CORTECO 12001700 - NBR - B1KL - 45x72x8 mm
A replacement should therefore not be selected solely on the basis of the 45x72x8 mm dimensions.
The CORTECO catalogue associates:
12001700 / 12001700B
with:
NEW HOLLAND / CNH
The product is classified within the agricultural sealing range.
When selecting the seal for a specific tractor, agricultural machine, transmission or mechanical assembly, the original part number and exact machine configuration should also be verified.
The product can be found under both references:
12001700
and
12001700B
Both numbers are used when identifying the CORTECO seal with the following specification:
45x72x8 mm - NBR - B1KL
For technical catalogue searches, purchasing systems and online searches, both references should be checked.
The dimensions 45x72x8 mm do not uniquely identify one CORTECO radial shaft seal.
CORTECO offers different seal designs in the same dimensions, including:
CORTECO 12001700 - NBR B1KL
CORTECO 12010958 - NBR BA
CORTECO 12011169 - NBR BASL
other material and design variants
Therefore, identical 45x72x8 mm dimensions do not automatically confirm full interchangeability.
The reference number, material, seal profile and requirements of the specific application must also be verified.

Before selecting an alternative to CORTECO 12001700, verify:
Shaft diameter 45 mm.
Housing bore diameter 72 mm.
Width 8 mm.
NBR material.
B1KL design.
CORTECO reference 12001700 / 12001700B.
OE reference when selecting the seal for a specific machine.
Operating medium.
Operating temperature.
Shaft speed.
The 45x72x8 mm dimensions alone are not sufficient to confirm interchangeability.
Before installation:
clean the shaft and housing bore thoroughly
inspect the shaft sealing surface
remove dirt, corrosion and burrs
protect the sealing lip from sharp edges
use a suitable installation tool
press the seal evenly into the housing
avoid deformation of the seal body
verify the correct installation orientation
A worn, corroded or damaged shaft surface can reduce the effectiveness and service life of the new seal.
