CORTECO 19030367 FPM/FKM SC 57.15x76.2x9.5 - Rotary Shaft Oil Seal

CORTECO 19030367 FPM/FKM SC 57.15x76.2x9.5 - Rotary Shaft Oil Seal

CORTECO 19030367 is an SC-type radial rotary shaft oil seal with dimensions 57.15x76.2x9.5 mm, manufactured from FPM/FKM fluoroelastomer, commonly referred to by the Viton material family name. CORTECO dimensional catalogue data confirms the exact combination 19030367 - FPM - SC - 57.15x76.2x9.5 mm and identifies the application as Nissan.

The FPM/FKM material makes this Simmerring particularly suitable for sealing applications involving oils, lubricants and elevated operating temperatures where a standard NBR seal may not provide the required material performance.

Dimensions 57.15x76.2x9.5 mm

The dimensions of CORTECO 19030367 are:

Shaft diameter: 57.15 mm
Housing diameter: 76.2 mm
Seal width: 9.5 mm

The dimensions correspond to imperial-derived values of approximately 2.25 x 3.00 x 0.375 inches, which explains the characteristic metric dimensions 57.15 mm, 76.2 mm and 9.5 mm.

The exact 57.15x76.2x9.5 mm dimensions are confirmed for CORTECO 19030367 in dimensional catalogue data.

SC Rotary Shaft Seal Design

The SC designation identifies the construction used for CORTECO 19030367. The manufacturer's dimensional data specifically lists this product as FPM SC.

The seal is designed for dynamic sealing between a rotating shaft and stationary housing. Its primary sealing lip works against the shaft surface to limit lubricant leakage from the mechanical assembly.

When replacing the seal, the SC construction should be considered together with its dimensions and material. A different seal profile with the same 57.15x76.2x9.5 mm dimensions should not automatically be considered technically identical.

FPM/FKM Fluoroelastomer

FPM and FKM refer to the fluoroelastomer material class used for this CORTECO seal. Viton is a well-known trade name associated with FKM fluoroelastomers.

Compared with conventional NBR, FKM is typically selected when the sealing position requires improved resistance to:

• elevated temperatures
• mineral oils
• synthetic lubricants
• fuels
• many hydrocarbons
• ageing and oxidation
• demanding chemical environments

The actual compatibility must always be verified against the specific fluid, concentration and operating temperature.

Why FKM is Used for Rotary Shaft Seals

The sealing lip of a rotary shaft seal operates continuously against a moving surface. Friction at the contact zone generates heat, while the elastomer is simultaneously exposed to lubricant and operating temperature.

FKM is therefore used in demanding shaft sealing positions where improved thermal and chemical resistance is required.

For CORTECO 19030367, the FPM material specification is explicitly confirmed in CORTECO dimensional catalogue data.

Nissan Application

CORTECO catalogue information identifies Nissan as the application associated with 19030367.

For vehicle-specific installation, compatibility should be confirmed using the original seal number, vehicle identification data or the corresponding OEM reference.

This is particularly important because a vehicle may use several different shaft seals depending on engine, transmission, axle and production version.

Rotary Shaft Sealing Function

CORTECO 19030367 is designed to provide dynamic sealing where a rotating shaft passes through a stationary housing.

Its principal functions include:

• retaining oil or lubricant
• reducing leakage along the rotating shaft
• separating the lubricated mechanism from its surroundings
• protecting the mechanical assembly
• maintaining controlled lubrication conditions around the shaft

Effective sealing also depends on the shaft surface finish, shaft runout, installation accuracy, lubrication and operating conditions.

Correct Replacement Identification

When selecting CORTECO 19030367, verify:

CORTECO reference: 19030367
Material: FPM / FKM
Design: SC
Dimensions: 57.15x76.2x9.5 mm
Shaft diameter: 57.15 mm
Housing diameter: 76.2 mm
Width: 9.5 mm
Application: Nissan

A standard seal with similar dimensions should not automatically be used as a replacement. The FKM material and SC construction are relevant parts of the technical specification.

Operational Advantages

Application identification: CORTECO catalogue data associates part number 19030367 with Nissan.

FAQ - CORTECO 19030367

What are the dimensions of CORTECO 19030367?
The seal measures 57.15x76.2x9.5 mm: 57.15 mm shaft diameter, 76.2 mm housing diameter and 9.5 mm width.

What material is CORTECO 19030367 made from?
CORTECO catalogue data specifies FPM, corresponding to the FKM fluoroelastomer material class.

Is FPM the same material family as FKM?
Yes. FPM and FKM are designation systems used for fluoroelastomer materials. Viton is a widely recognized trade name for certain FKM materials.

What does SC mean on CORTECO 19030367?
SC identifies the specific radial shaft seal construction. CORTECO lists part number 19030367 as FPM SC.

Is CORTECO 19030367 a rotary shaft oil seal?
Yes. It is a radial shaft sealing element designed to retain lubricant around a rotating shaft.

Is CORTECO 19030367 used for Nissan applications?
Yes. CORTECO dimensional catalogue data identifies Nissan as the application for this part number.

Why are the dimensions 57.15x76.2x9.5 mm unusual?
They originate from imperial dimensions: approximately 2.25 inch shaft diameter, 3 inch housing diameter and 0.375 inch width.

Can an NBR 57.15x76.2x9.5 seal replace this FKM version?
Not automatically. Although the dimensions may match, NBR and FKM have different temperature and chemical resistance characteristics. The material required by the original application should be retained.
