GRN® 15x32x7 NBR TC is a double lip radial shaft seal / rotary shaft seal / oil seal with nominal dimensions of 15x32x7 mm. It is manufactured from NBR - Nitrile Butadiene Rubber and uses the TC double lip configuration. The exact product is identified by reference 15X32X7 and EAN 5903641601559.
The complete technical identification is:
GRN® + 15X32X7 + NBR + TC
Verified identification data:
Brand: GRN®
Reference: 15X32X7
EAN: 5903641601559
Product type: Radial shaft seal / rotary shaft seal / oil seal
Design: TC
Configuration: Double lip
Material: NBR
Material name: Nitrile Butadiene Rubber
Dimensions: 15x32x7 mm
Shaft diameter d: 15 mm
Outside diameter D: 32 mm
Width B: 7 mm
Primary sealing lip: Spring-loaded
Additional lip: Auxiliary dust lip
The exact product page confirms the GRN brand, reference 15X32X7, EAN 5903641601559 and principal dimensions of 15 mm, 32 mm and 7 mm.
The nominal installation dimensions are:
d: 15 mm - nominal shaft diameter
D: 32 mm - nominal seal outside diameter / housing bore diameter
B: 7 mm - nominal axial width
Complete dimensions:
15x32x7 mm
These three dimensions are confirmed for the exact GRN® product.
The first dimension identifies the nominal shaft diameter on which the primary dynamic sealing lip operates.
The second identifies the nominal outside diameter of the seal installed in the housing.
The third specifies the nominal axial width of the seal.
All three dimensions must be retained when identifying a replacement.
The exact product is catalogued as:
15x32x7 NBR TC Oil Seal Double Lip.
The TC configuration uses two functional sealing lips:
Primary sealing lip - the dynamic lip operating against the rotating shaft.
Garter spring - supports radial contact of the primary sealing edge against the shaft.
Auxiliary dust lip - provides an additional barrier on the external side of the primary sealing zone.
The auxiliary lip should not be interpreted as a second identical oil-retaining lip. Its principal role in the TC configuration is external protection of the primary sealing area.
No left-hand or right-hand hydrodynamic direction has been confirmed for this exact product.
The primary dynamic sealing lip operates against a shaft with a nominal diameter of 15 mm.
Its circumferential garter spring supports contact between the sealing edge and shaft surface. The auxiliary lip is positioned toward the external side and provides an additional barrier against contaminants entering the primary sealing zone.
The product is therefore a dynamic radial sealing element for a rotating shaft, rather than a static seal.
The verified material designation for this exact product is:
NBR - Nitrile Butadiene Rubber.
NBR is part of the product's exact technical identification and distinguishes this variant from seals of identical dimensions manufactured from other elastomers.
The current product description contains generic NBR temperature and media-resistance information. However, those values do not identify the precise NBR compound used for this exact GRN® reference.
For that reason, this technical card does not assign a product-specific:
Shore A hardness
minimum operating temperature
maximum operating temperature
maximum operating pressure
maximum rotational speed
maximum shaft surface speed
These parameters should be confirmed from documentation for the exact compound before being treated as operating limits.
The designation can be interpreted as:
15 - nominal shaft diameter in mm
32 - nominal outside diameter in mm
7 - nominal axial width in mm
NBR - Nitrile Butadiene Rubber
TC - double lip radial shaft seal configuration
GRN® - product brand
Additional exact identifiers:
Reference: 15X32X7
EAN: 5903641601559
For database, purchasing and technical identification, retain:
GRN® + 15X32X7 + NBR + TC
An important distinction exists within the same nominal dimensions.
The GRN® range also contains a 15x32x7 NBR SC single-lip variant, while the product described on this page is the 15x32x7 NBR TC double-lip variant.
Therefore:
15x32x7 NBR TC - double lip
15x32x7 NBR SC - single lip
The nominal dimensions alone cannot distinguish these products. The TC or SC construction designation must also be checked.
This distinction is particularly important for search indexing and prevents technical cannibalization between the two 15x32x7 NBR product variants.
A GRN® 15x32x7 FPM TC variant also exists with the same nominal dimensions.
The critical distinction is the elastomer:
This product: 15x32x7 NBR TC
Other variant: 15x32x7 FPM TC
They should not be treated as the same technical product solely because their dimensions and TC profile match.
Material compatibility with the operating medium and temperature conditions must be assessed for the actual application.
When selecting a replacement for GRN® 15x32x7 NBR TC, verify at least:
Identical 15x32x7 mm dimensions do not automatically establish full technical interchangeability.
In particular, 15x32x7 NBR TC, 15x32x7 NBR SC and 15x32x7 FPM TC are distinct technical variants despite sharing the same nominal dimensions.
A CORTECO, SKF, Simrit or another manufacturer's seal should not be described as a direct replacement without verifying its material, lip geometry, design and application requirements.

It is a double lip radial shaft seal / rotary shaft seal manufactured from NBR and catalogued as a TC oil seal.
The exact reference is 15X32X7 and the EAN is 5903641601559.
TC identifies the double lip configuration, with a spring-loaded primary sealing lip and an auxiliary dust lip.
No. The TC variant is double lip, while the GRN® SC variant with the same 15x32x7 dimensions is single lip.
No. Although the dimensions and TC configuration can be identical, NBR and FPM are different elastomer materials. The material must be selected according to the actual operating conditions.
Not automatically. Dimensions, material, lip configuration and any application-specific construction features must be verified.
No left-hand or right-hand hydrodynamic direction has been confirmed for this exact GRN® reference.
