Honda OE Reference Numbers

CORTECO 19026199 is identified with the following Honda OE numbers:

HONDA: 91216-PL3-000
HONDA: 91216-PL3-003
HONDA: 91216-PL3-005

These references may also be searched without separators:

91216PL3000
91216PL3003
91216PL3005

When selecting a replacement, the OE reference and installation position should be checked together with the seal dimensions and construction.

Dimensions of CORTECO 19026199

The principal installation dimensions are:

d: 26 mm
D: 42 mm
B: 7 mm

This means the seal is designed for a nominal 26 mm shaft diameter and 42 mm housing bore, with an installation width of 7 mm.

The 26x42x7 mm dimensions alone should not be used to determine interchangeability. The LHTC design, ACM material and Honda OE reference are also important identification parameters.

LHTC Design with Dust Lip

CORTECO 19026199 uses an LHTC sealing configuration with an additional dust lip.

The primary sealing lip operates against the rotating shaft and helps retain transmission lubricant inside the mechanical assembly.

The auxiliary dust lip provides an additional barrier between the external environment and the primary sealing zone, helping reduce the ingress of:

• dust
• dirt
• fine contaminants
• external debris

This additional protection is useful in transmission applications where contamination of the shaft contact area can affect sealing performance and service life.

ACM Polyacrylate Rubber

ACM, polyacrylate rubber, is an elastomer used extensively in automotive and transmission sealing applications.

Compared with conventional NBR, ACM is selected for applications requiring an appropriate combination of oil resistance and elevated-temperature capability.

Typical applications for ACM sealing materials include:

• transmissions
• gearboxes
• drivetrain assemblies
• rotating shaft seals
• automotive oil sealing systems
• lubricated mechanical components

Actual compatibility should always be verified for the specific transmission fluid, temperature and operating conditions.

Manual Transmission Shaft Sealing

CORTECO 19026199 is intended for sealing a shaft in a manual transmission application.

During operation, the shaft rotates relative to the stationary transmission housing. The radial shaft seal creates a controlled dynamic sealing interface around the shaft.

Its principal functions are to:

• retain transmission lubricant
• reduce oil leakage along the shaft
• maintain lubrication inside the transmission
• separate the lubricated assembly from the external environment
• protect the primary sealing area against contamination

The dust lip provides an additional protective function on the external side of the sealing system.

CORTECO 19026199 for Honda

The Honda references 91216-PL3-000, 91216-PL3-003 and 91216-PL3-005 allow CORTECO 19026199 to be identified for specific Honda transmission applications.

Compatibility should be confirmed using the OE number, vehicle version and transmission specification before installation.

The fact that the seal is associated with Honda does not mean that it fits every Honda model or gearbox.

Selecting a Replacement 26x42x7 Oil Seal

When identifying a replacement, verify:

Manufacturer: CORTECO
Part number: 19026199
Dimensions: 26x42x7 mm
Material: ACM polyacrylate rubber
Design: LHTC
Dust lip: Yes
Installation position: Transmission shaft
Honda OE: 91216-PL3-000 / 91216-PL3-003 / 91216-PL3-005

A generic 26x42x7 mm oil seal should not automatically be considered equivalent.

Oil seals with identical dimensions may be manufactured from NBR, FKM, ACM or other elastomers and can also differ in sealing lip geometry and application specification.

Operational Advantages

ACM material: suitable for many transmission applications involving lubricants and elevated operating temperatures.

LHTC construction: application-specific radial shaft sealing configuration.

Additional dust lip: provides an extra barrier against external contamination.

26x42x7 mm dimensions: clearly defined installation geometry for replacement identification.

Transmission application: designed for dynamic sealing of a rotating gearbox shaft.

Honda OE identification: three OE references support accurate replacement selection for compatible applications.

FAQ - CORTECO 19026199

What are the dimensions of CORTECO 19026199?
The seal measures 26x42x7 mm, with a 26 mm inside diameter, 42 mm outside diameter and 7 mm width.

What material is CORTECO 19026199 made from?
It is manufactured from ACM, polyacrylate rubber.

What is CORTECO 19026199 used for?
It is a radial shaft oil seal intended for specific manual transmission shaft applications.

Does CORTECO 19026199 have a dust lip?
Yes. The LHTC configuration includes an additional dust lip that helps protect the primary sealing area against contamination.

Which Honda OE numbers correspond to CORTECO 19026199?
The relevant references are 91216-PL3-000, 91216-PL3-003 and 91216-PL3-005.

Is ACM the same material as NBR?
No. ACM is polyacrylate rubber, while NBR is nitrile butadiene rubber. Their temperature and chemical resistance characteristics differ.

Why is ACM used for transmission oil seals?
ACM provides useful resistance to oils and elevated temperatures, which makes it suitable for many automotive transmission and drivetrain sealing applications.
