CORTECO 19017038 38x58x11 ACM LHTC Transmission Rotary Shaft Seal

CORTECO 19017038 38x58x11 ACM LHTC Transmission Rotary Shaft Seal

CORTECO 19017038, also listed in current catalogues as 19017038B, is an ACM transmission rotary shaft seal / oil seal with the CORTECO LHTC design and dimensions of 38x58x11 mm. The seal has a 38 mm inside diameter, 58 mm outside diameter and 11 mm width.

This exact reference features a left-hand dynamic twist and an additional dust lip, both of which are important when identifying a technically suitable replacement.

The key product relationship is:

CORTECO 19017038 / 19017038B → 38x58x11 mm → ACM → LHTC → left-hand twist → additional dust lip → transmission shaft seal

CORTECO 19017038 / 19017038B – characteristics

The key product specifications are:

• Manufacturer: CORTECO
• Part number: 19017038
• Current/alternative reference: 19017038B
• CORTECO trade number: 82017038
• Product type: rotary shaft seal / oil seal
• Catalogue application: transmission shaft
• Design: LHTC
• Material: ACM – polyacrylate rubber
• Inside diameter: 38 mm
• Outside diameter: 58 mm
• Width: 11 mm
• Dimensions: 38x58x11 mm
• Dynamic twist direction: left-hand twist
• Dust protection: additional dust lip
• EAN: 3358960170385

The combination 38x58x11 mm, ACM, LHTC, left-hand twist and additional dust lip provides a much more precise identification than dimensions alone.

CORTECO 19017038 dimensions

The dimensional designation should be written as:

38x58x11 mm

These dimensions are an essential identification parameter, but they do not by themselves confirm interchangeability with another 38x58x11 oil seal.

For this specific CORTECO reference, the following combination should be checked:

38x58x11 + ACM + LHTC + left-hand twist + dust lip

ACM polyacrylate rotary shaft seal

CORTECO specifies the material of 19017038 / 19017038B as:

ACM – polyacrylate rubber

ACM is therefore an important part of the technical specification and should be considered when selecting an alternative seal.

A 38x58x11 mm seal made from NBR, FPM/FKM, VMQ or another elastomer should not automatically be considered interchangeable simply because its dimensions are identical.

Material, seal geometry, dynamic features and the actual application must also be compared.

LHTC design – CORTECO 19017038

The design designation associated with this exact CORTECO reference is:

LHTC

For accurate product identification, the designation should remain connected with the exact part number and dimensions:

CORTECO 19017038 LHTC 38x58x11 ACM

Searching only for:

38x58x11 oil seal

may return multiple seals with different materials and functional designs.

For this reason, LHTC is an important additional identifier for engineers, mechanics, maintenance specialists and professional parts buyers.

Left-hand twist oil seal

CORTECO 19017038B is specified with a:

left-hand twist

This is an important dynamic feature of the sealing surface.

When selecting an alternative rotary shaft seal, the twist direction should therefore be considered together with the dimensions, material and seal design.

A different 38x58x11 seal with another directional structure should not automatically be treated as a direct equivalent.

For technical searches, this reference may therefore also be described as:

38x58x11 left-hand oil seal
38x58x11 left-hand rotary shaft seal
CORTECO LHTC left-hand shaft seal

Additional dust lip

CORTECO 19017038B is also specified with an additional dust lip.

This secondary sealing feature is relevant when comparing the product with simpler shaft seals.

The dust lip provides an additional barrier on the external side of the sealing arrangement, helping separate the primary sealing area from external contamination.

For replacement selection, the presence of this additional lip should therefore be checked rather than relying only on the three nominal dimensions.

CORTECO 19017038 transmission shaft seal

Current catalogue data classify CORTECO 19017038B as a transmission shaft seal.

Depending on the catalogue and application database, descriptions can appear as:

transmission shaft seal
gearbox shaft seal
manual transmission shaft seal
automatic transmission shaft seal
transmission oil seal

Because catalogue terminology can vary between specific applications, the exact transmission position should be confirmed using the OE number, CORTECO reference and vehicle data.

This is more reliable than assigning the seal universally to one transmission type.

CORTECO 19017038 – Toyota and Lexus OE references

This CORTECO seal is associated with several Toyota and Lexus OE numbers, including:

TOYOTA 9031130032
TOYOTA 9031138030
TOYOTA 9031138032
TOYOTA 9031138140
LEXUS 9031138032

One particularly important identification relationship is:

Toyota/Lexus 9031138032 → CORTECO 19017038B → 38x58x11 mm → ACM → LHTC

This OE relationship is useful for customers searching by an original equipment number rather than by the CORTECO aftermarket reference.

Toyota 90311-38032 oil seal

The Toyota OE reference:

90311-38032

is the hyphenated representation of:

9031138032

and is associated with CORTECO 19017038B.

This means customers may search for the same component using terms such as:

Toyota 90311-38032 oil seal
Toyota 9031138032 shaft seal
90311-38032 transmission seal
9031138032 CORTECO
CORTECO 19017038 Toyota

For a specific vehicle, compatibility should still be confirmed against the OE number, transmission version and vehicle identification data.

CORTECO 19017038 – Mazda BV8B17335

Another OE reference associated with CORTECO 19017038B is:

MAZDA BV8B17335

This creates the identification relationship:

Mazda BV8B17335 → CORTECO 19017038B → 38x58x11 mm → ACM → LHTC

Catalogue application data also associate this reference with selected Mazda applications.

The OE number should remain the primary reference when confirming fitment for a specific vehicle.

Toyota applications

Catalogue application data associate CORTECO 19017038B with selected versions of vehicles including:

Toyota Celica
Toyota Corolla
Toyota Hiace
Toyota Hilux
Toyota LiteAce
Toyota Previa / Estima

This does not mean that CORTECO 19017038 fits every version of these models.

Different production years, engines, transmissions and drivetrains may use different seals.

For this reason, final fitment should be based primarily on:

OE number + CORTECO reference + vehicle/transmission data

rather than the vehicle model name alone.

CORTECO 82017038 – what is this number?

In addition to:

19017038
19017038B

this product is associated with the CORTECO trade number:

82017038

The same seal may therefore be searched for using several identifiers:

CORTECO 19017038
CORTECO 19017038B
CORTECO 82017038

For final technical identification, these references should correspond to:

38x58x11 mm + ACM + LHTC

CORTECO 19017038 or 19017038B?

The reference 19017038 appears in older product identification, while current aftermarket catalogues commonly list:

19017038B

Both reference variants are therefore useful on an international product page because buyers may search using older catalogues, existing stock labels, OE cross-reference databases or current aftermarket databases.

The manufacturer reference shown on the actual supplied packaging should be used for final physical stock identification.

Why is 38x58x11 alone not enough?

Two rotary shaft seals can have identical nominal dimensions without being technically identical.

For CORTECO 19017038, the relevant specification includes:

38 mm inside diameter
58 mm outside diameter
11 mm width
ACM material
LHTC design
left-hand twist
additional dust lip

Therefore, a generic 38x58x11 oil seal should not automatically be considered a direct replacement.

This distinction is particularly important for dynamic transmission sealing applications.

How to select an alternative for CORTECO 19017038

When comparing another seal with CORTECO 19017038 / 19017038B, check at least:

1. CORTECO 19017038 / 19017038B reference
2. 82017038 trade number
3. 38 mm inside diameter
4. 58 mm outside diameter
5. 11 mm width
6. ACM material
7. LHTC design
8. left-hand dynamic twist
9. additional dust lip
10. OE reference and exact transmission application

Identical dimensions alone do not guarantee interchangeability.

A replacement should match the relevant construction and application requirements as well as the nominal dimensions.
