Corteco 16015273 NBR DDHSL22-70 22x37x2.9/9.2 Shaft Seal

Corteco 16015273 NBR DDHSL22-70 22x37x2.9/9.2 Shaft Seal

Corteco 16015273 / 16015273B is a special-profile shaft seal manufactured from NBR - Nitrile Butadiene Rubber.

Its complete dimensions are:

22x37x2.9/9.2 mm

Corteco identifies the seal design as DDHSL22-70.

Unlike a conventional radial shaft seal specified by a single nominal width, this product has a characteristic 2.9/9.2 mm profile. This geometry is an essential part of the product specification and must be considered when selecting a replacement.

Corteco 16015273 - Dimensions

d - Inside diameter: 22 mm
D - Outside diameter: 37 mm
Profile height: 2.9/9.2 mm
Complete dimensions: 22x37x2.9/9.2 mm
Material: NBR - Nitrile Butadiene Rubber

Manufacturer: Corteco
Product reference: 16015273 / 16015273B

What Does 22x37x2.9/9.2 Mean?

The designation 22x37x2.9/9.2 mm defines the characteristic geometry of the seal:

22 mm - inside diameter
37 mm - outside diameter
2.9/9.2 mm - stepped profile height

The last value is particularly important.

This is not simply a conventional 22x37 seal with one nominal width. The 2.9/9.2 mm specification describes the characteristic profile required for the installation.

For correct identification, the complete dimension should therefore be retained:

22x37x2.9/9.2 mm

DDHSL22-70 - Corteco Design

Corteco specifies the design of this seal as:

DDHSL22-70

The designation may also appear in dimensional catalogues as:

DDHSL(22-70)

This design code is an important part of the product specification and helps distinguish Corteco 16015273B from other seals with a 22 mm inside diameter and 37 mm outside diameter.

The correct identification is:

NBR + DDHSL22-70 + 22x37x2.9/9.2 mm

Special 2.9/9.2 mm Profile

One of the most important characteristics of Corteco 16015273 is its 2.9/9.2 mm profile.

This geometry means that the seal cannot be identified correctly by searching only for:

22x37 mm seal

A replacement must correspond to the complete profile and installation geometry.

This makes the Corteco product number particularly important when identifying the correct part.

Why the Corteco 16015273 Reference Matters

The reference 16015273 / 16015273B identifies a specific Corteco sealing component.

For this type of seal, the most reliable identification combines:

Corteco product reference,
DDHSL22-70 design,
NBR material,
22x37x2.9/9.2 mm dimensions.

Using the complete specification reduces the risk of confusing this product with a conventional 22x37 radial shaft seal.

NBR Nitrile Rubber

Corteco 16015273B is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is a widely used elastomer in sealing technology and is compatible with many common mineral oils, greases and lubricants.

Actual suitability must always be evaluated against the specific:

medium,
temperature,
pressure,
operating conditions.

Material identification is therefore an important part of replacement selection.

16015273 vs 16015273B

The product can be searched using the Corteco reference:

16015273

and is listed in dimensional catalogues as:

16015273B

When searching for the seal, both forms of the reference may therefore be useful.

The essential technical identification remains:

16015273B + DDHSL22-70 + NBR + 22x37x2.9/9.2 mm

Corteco 16015273 vs Standard 22x37 Oil Seal

A standard 22x37 radial shaft oil seal should not automatically be considered equivalent to Corteco 16015273.

The Corteco product has a specific:

DDHSL22-70 design,
2.9/9.2 mm profile,
NBR material,
16015273B product reference.

Two seals can therefore share the same 22 mm and 37 mm diameters while having significantly different geometries.

How to Select Corteco 16015273

For correct replacement identification, verify the complete specification:

Manufacturer: Corteco
Product reference: 16015273 / 16015273B
Inside diameter: 22 mm
Outside diameter: 37 mm
Profile: 2.9/9.2 mm
Material: NBR
Design: DDHSL22-70

The strongest identification is:

Corteco 16015273B + NBR + DDHSL22-70 + 22x37x2.9/9.2 mm

Do not select a replacement based only on the 22x37 mm diameters.
