CORTECO 12014525 - product characteristics

CORTECO 12014525 is a dedicated valve stem seal designed for installation in the cylinder head of an internal combustion engine.

It is not a conventional radial shaft oil seal. The VA3 12-1 construction is designed to control the amount of oil passing through the area where the valve stem operates inside the valve guide.

Technical data

CORTECO 12014525 dimensions

The complete dimensional specification is:

12x16/20x15 mm

where:

• 12 mm - inside diameter

• 16 mm - first outside diameter

• 20 mm - second outside diameter

• 15 mm - height

The complete 12x16/20x15 mm geometry is an important identification feature.

This valve stem seal should not be selected solely on the basis of its 12 mm inside diameter.

What does CORTECO 12014525 VA3 12-1 mean?

12014525 is the CORTECO catalogue reference.

VA3 12-1 identifies the design of this valve stem seal.

FPM identifies the fluorocarbon elastomer used for the sealing component.

The complete technical identification is therefore:

CORTECO 12014525 - VA3 12-1 - FPM - 12x16/20x15 mm

Using the complete designation helps distinguish this component from other valve stem seals with a 12 mm inside diameter.

CORTECO 12014525 vs CORTECO 49472954

CORTECO 12014525 is an older reference that remains important for product identification, cross-referencing and search.

In newer catalogue data, the corresponding replacement reference is:

CORTECO 49472954

replacing:

CORTECO 12014525

Both numbers may therefore be encountered when searching for this valve stem seal.

The complete technical specification and OE reference should always be verified when comparing old and new catalogue numbers.

FPM material

CORTECO 12014525 is manufactured from FPM fluorocarbon elastomer.

FPM is widely used in demanding engine sealing applications due to its resistance to elevated temperatures and its compatibility with many oils and other media encountered in engine environments.

Material selection is particularly important for valve stem seals because they operate under the demanding thermal conditions present in the cylinder head.

Function of the valve stem seal

The valve stem seal operates around the valve stem and valve guide.

Its purpose is to control the amount of lubricating oil reaching the interface between these components.

The seal limits excessive oil passage while allowing the lubrication necessary for correct movement of the valve stem inside the guide.

This function is fundamentally different from that of a conventional radial shaft seal used on a rotating shaft.

MERCEDES-BENZ OE 4220530196

CORTECO 12014525 is associated with the MERCEDES-BENZ OE reference:

4220530196

Common formatting variations include:

• 4220530196

• 422 053 01 96

• A4220530196

• A 422 053 01 96

These different formats are useful when searching OE catalogues and parts databases.

Compatibility should nevertheless be confirmed for the specific engine and installation position before ordering.

Cross-reference numbers

Cross-reference numbers associated with CORTECO 12014525 / MERCEDES-BENZ 4220530196 include:

• 422 053 01 96

• CORTECO 12014525 valve stem seal

• CORTECO 49472954 valve stem seal

Both the older 12014525 reference and the newer 49472954 reference are useful for product identification and search.

Selection and interchangeability

Before purchasing CORTECO 12014525, verify:

1. CORTECO reference 12014525 or its corresponding newer reference.

2. VA3 12-1 design.

3. FPM material.

4. Inside diameter of 12 mm.

5. First outside diameter of 16 mm.

6. Second outside diameter of 20 mm.

7. Height of 15 mm.

8. MERCEDES-BENZ OE reference 4220530196.

9. Engine type and installation position.

An identical 12 mm inside diameter alone does not establish interchangeability with another valve stem seal.

The complete geometry, construction, material and OE reference must also be considered.

CORTECO 12014525 vs conventional radial shaft seal

CORTECO 12014525 should not be confused with a conventional rotary shaft oil seal.

A standard radial shaft seal is normally designed to seal a rotating shaft. CORTECO 12014525 is specifically designed for the reciprocating movement and lubrication requirements of a valve stem operating inside a valve guide.

Its VA3 12-1 construction and 12x16/20x15 mm geometry are therefore essential parts of the product specification.

Installation

Valve stem seals require careful and clean installation.

Before fitting the seal, inspect:

• valve stem

• valve guide

• installation surface

• mating components

During installation, protect the sealing element against cuts or damage from sharp edges and grooves on the valve stem.

The seal should be installed axially using the installation procedure and appropriate tooling specified for the particular engine.
