CORTECO 19016601 FPM RHTC 20x30x7 mm - Radial Shaft Oil Seal Simmerring

CORTECO 19016601 FPM RHTC 20x30x7 mm - Radial Shaft Oil Seal Simmerring

CORTECO 19016601 FPM RHTC 20x30x7 mm is a radial shaft oil seal from the Simmerring product family, manufactured from FPM fluoroelastomer. It has a 20 mm inside diameter, 30 mm outside diameter and 7 mm width. The RHTC designation identifies a directional seal construction; catalogue data for this specific product indicates right-hand directional sealing geometry and an additional dust lip.

Technical data - CORTECO 19016601

What does CORTECO 19016601 FPM RHTC mean?

The complete product designation should be considered as a single technical identification:

CORTECO - manufacturer.

19016601 - CORTECO catalogue part number identifying this specific seal.

FPM - sealing material belonging to the fluoroelastomer family.

RHTC - construction designation. For CORTECO 19016601, catalogue data identifies a right-hand directional sealing structure and an additional dust lip.

20x30x7 mm - nominal dimensions: 20 mm inside diameter, 30 mm outside diameter and 7 mm width.

The complete designation is important because other 20x30x7 mm radial shaft seals can have different materials and sealing constructions.

Dimensions of CORTECO 19016601

The nominal dimensions are:

20x30x7 mm

where:

• inside diameter d: 20 mm
• outside diameter D: 30 mm
• width B: 7 mm

These dimensions define the principal installation geometry but do not independently determine interchangeability.

For correct identification, the dimensions should be considered together with:

FPM + RHTC + CORTECO 19016601

FPM fluoroelastomer

CORTECO 19016601 is manufactured from:

FPM

FPM belongs to the fluoroelastomer material family. The designation FKM is also widely used internationally for this general class of elastomers.

Fluoroelastomers are commonly selected for sealing applications involving many oils, fuels and lubricants and for operating conditions where greater thermal and chemical resistance may be required than in many conventional NBR applications.

The suitability of a specific FPM compound always depends on the actual operating medium, temperature and application.

For this reason, a universal temperature range is not assigned here to CORTECO 19016601 without confirmed manufacturer data for the specific compound.

FPM, FKM and Viton

FPM and FKM are designations associated with the same general fluoroelastomer family, although they originate from different nomenclature systems.

Viton is a trademark for specific fluoroelastomer materials.

Therefore, CORTECO 19016601 should technically be described according to its confirmed material specification:

FPM

It should not automatically be described as a Viton seal unless the use of that specific branded material is confirmed.

Construction of CORTECO 19016601 RHTC

CORTECO 19016601 is not defined only by its 20x30x7 mm dimensions.

An important part of the specification is:

RHTC

For this specific CORTECO reference, catalogue information identifies:

• directional sealing construction
• right-hand sealing structure
• additional dust lip

The primary sealing section operates against the rotating shaft surface, while the additional dust lip helps separate the main sealing area from external contamination.

The directional characteristic is technically important when selecting an alternative seal.

RHTC vs LHTC

RHTC and LHTC should not automatically be treated as interchangeable constructions.

The confirmed designation for CORTECO 19016601 is:

FPM RHTC 20x30x7 mm

If another seal has the same 20x30x7 mm dimensions but an LHTC designation, the shaft rotation direction and the required directional construction should be checked before installation.

Identical dimensions do not eliminate functional differences between directional seal designs.

CORTECO 19016601 vs a standard 20x30x7 oil seal

Various radial shaft seals are available in the nominal size:

20x30x7 mm

They may differ in:

• elastomer material
• primary sealing lip construction
• additional dust lip
• directional sealing structure
• outside diameter construction
• application requirements

Therefore, the description:

20x30x7 oil seal

is not sufficient to uniquely identify CORTECO 19016601.

The more precise identification is:

CORTECO 19016601 FPM RHTC 20x30x7 mm

CORTECO 19016601 vs NBR 20x30x7

NBR and FPM belong to different elastomer families.

Consequently:

NBR 20x30x7

should not automatically be considered equivalent to:

CORTECO 19016601 FPM RHTC 20x30x7

even when the principal dimensions are identical.

Material compatibility with the operating medium, temperature and application requirements must be considered before substitution.

CORTECO 19016601 vs TC 20x30x7

TC and RHTC are different seal construction designations.

A conventional:

TC 20x30x7

should therefore not automatically be treated as a direct technical replacement for:

CORTECO 19016601 FPM RHTC 20x30x7

based only on dimensions.

Before substitution, compare:

• elastomer material
• sealing lip geometry
• directional characteristics
• additional dust lip
• operating conditions
• application requirements

Confirmed application of CORTECO 19016601

Catalogue information identifies CORTECO 19016601, among its applications, as a:

radial shaft seal for an oil pump

The CORTECO dimensional catalogue associates part number 19016601 with MITSUBISHI applications.

This is a catalogue application for this specific CORTECO reference, rather than a general application assigned to all FPM 20x30x7 mm seals.

A vehicle application should not be selected solely by manufacturer name. The OE reference and exact application should also be verified.

Confirmed OE references

Catalogue data for CORTECO 19016601 includes the following OE references:

MITSUBISHI

• MD095355
• MD168057
• MD365697

HYUNDAI

• 2142133144
• 4314311010

These OE references are useful for product identification.

Compatibility should still be confirmed for the exact vehicle, engine and installation position before installation.

Alternative designations and reference numbers

Natural product designation variants include:

• CORTECO 19016601
• 19016601 CORTECO
• CORTECO 19016601 FPM
• CORTECO 19016601 RHTC
• CORTECO 19016601 FPM RHTC
• 19016601 FPM RHTC
• CORTECO 19016601 20x30x7
• CORTECO 19016601 FPM RHTC 20x30x7
• CORTECO 19016601B
• 19016601B CORTECO
• CORTECO RHTC 20x30x7
• FPM RHTC 20x30x7
• CORTECO Simmerring 20x30x7
• CORTECO oil seal 20x30x7
• CORTECO shaft seal 20x30x7

The reference 19016601B appears in aftermarket catalogue data as a commercial product reference. The base reference used in the dimensional catalogue is 19016601.

Confirmed OE references should be treated separately from alternative ways of writing the CORTECO product number.

Selection and interchangeability

Before selecting a replacement for CORTECO 19016601, verify:

• complete CORTECO reference 19016601
• dimensions 20x30x7 mm
• 20 mm shaft diameter
• 30 mm housing diameter
• 7 mm width
• FPM material
• RHTC construction
• directional sealing geometry
• additional dust lip
• shaft rotation direction
• operating medium
• operating temperature of the actual application
• OE reference when selecting the seal for a vehicle

Identical 20x30x7 mm dimensions do not automatically mean full technical interchangeability.

Installation of CORTECO 19016601

Before installation, clean the shaft and seal housing and inspect the surface that will contact the sealing lip.

The working surface should be free from:

• sharp edges
• burrs
• corrosion
• deep scratches
• excessive wear grooves

The seal should be pressed into the housing evenly and squarely using an appropriate installation tool.

Installation force should not be applied directly to the functional sealing lip.

Because RHTC is a directional construction, correct orientation and shaft rotation direction should be verified before installation.

Inspection before operation

After installation, check:

• correct seating of the seal
• absence of misalignment
• correct orientation
• shaft surface condition
• absence of sealing lip damage

A new Simmerring cannot compensate for severe wear of the shaft surface.

If a pronounced wear groove is present at the sealing lip contact area, replacing the seal alone may not eliminate the cause of leakage.

FAQ - CORTECO 19016601
