CORTECO 19016512 VMQ LHTC 72x96x9 mm - Silicone Rotary Shaft Oil Seal

CORTECO 19016512 VMQ LHTC 72x96x9 mm - Silicone Rotary Shaft Oil Seal

CORTECO 19016512 VMQ LHTC 72x96x9 mm is a radial rotary shaft seal manufactured from VMQ silicone rubber. This CORTECO oil seal has an inside diameter of 72 mm, an outside diameter of 96 mm and a width of 9 mm. The LHTC designation identifies its construction profile, which must be considered when selecting a replacement. VMQ silicone rubber is known for maintaining flexibility across a wide temperature range, although the exact operating limits of this product require confirmation from the manufacturer.

What Does CORTECO 19016512 VMQ LHTC 72x96x9 Mean?

The complete designation identifies the manufacturer, product reference, sealing material, construction profile and nominal dimensions.

CORTECO - the manufacturer's brand.

19016512 - the product identification number.

VMQ - the technical designation for a group of silicone rubber elastomers used in sealing applications.

LHTC - the seal construction profile designation. Its exact geometry should be verified using the manufacturer's technical drawing.

72x96x9 mm - nominal dimensions:

• 72 mm - inside diameter.

• 96 mm - outside diameter.

• 9 mm - width.

VMQ Silicone Rubber - Material Properties

VMQ is a silicone-based elastomer used in sealing applications requiring particular temperature-related properties and flexibility.

Temperature Resistance

VMQ silicone rubber is known for retaining flexibility at low temperatures and offering good resistance to elevated temperatures.

However, this does not mean that every VMQ oil seal has the same permissible operating temperature range.

The operating limits of CORTECO 19016512 depend on the specific rubber compound, seal construction, sealing medium and application conditions.

Chemical Resistance

Compatibility between VMQ and oils, greases or other fluids depends on the specific substance and operating temperature.

Silicone rubber should not automatically be considered resistant to all mineral oils, fuels, solvents or industrial fluids.

Chemical compatibility must be verified for the intended application.

Mechanical Properties

VMQ differs from NBR and FKM in its mechanical characteristics and behavior when exposed to various fluids.

For this reason, the sealing material should not be changed without checking the equipment's operating requirements.

LHTC Seal Profile - Why Construction Matters

The LHTC designation is an important part of identifying CORTECO 19016512.

It should not automatically be considered equivalent to common profiles such as BA, BASL, B1, B2SL or TC.

Differences between seal profiles may involve:

• Primary sealing lip geometry.

• Presence of an additional protective lip.

• Outer-case construction.

• Spring or other loading elements.

• Shaft surface requirements.

• Directional sealing characteristics.

Without a product-specific technical drawing, the exact number of sealing lips or spring arrangement should not be assumed.

Typical Applications of VMQ Rotary Shaft Seals

Radial shaft seals manufactured from VMQ may be used in appropriately designed mechanical systems where silicone rubber properties are required.

Potential applications include:

• Rotating shaft assemblies.

• Industrial equipment.

• Selected gearboxes and mechanical drives.

• Equipment operating under varying temperature conditions.

• Specialized sealing systems.

These are general examples of VMQ sealing applications, not a verified list of machines compatible with CORTECO 19016512.

VMQ vs NBR vs FKM - Material Comparison

An NBR or FKM seal should not automatically replace a VMQ seal simply because its nominal dimensions are identical.

Material selection can affect chemical compatibility, friction, durability and permissible operating conditions.

How to Select the Correct CORTECO 19016512 Oil Seal

Before ordering, verify:

1. CORTECO product reference 19016512.

2. Shaft diameter - 72 mm.

3. Housing bore diameter - 96 mm.

4. Seal width - 9 mm.

5. VMQ sealing material.

6. LHTC construction profile.

7. Type of sealing medium.

8. Operating temperature.

9. Shaft rotational speed.

10. Equipment manufacturer requirements.

When selecting a replacement, compare the original seal with the manufacturer's technical documentation.

Dimensions alone do not guarantee interchangeability.

Installation Guidelines

Before installing the CORTECO 72x96x9 mm oil seal, inspect the shaft and housing bore.

Check for:

• Shaft wear grooves.

• Corrosion.

• Scratches.

• Sharp edges.

• Contamination.

• Excessive shaft runout.

• Bearing play.

• Incorrect housing dimensions.

Install the seal evenly using an appropriate mounting tool.

Avoid damaging the sealing surfaces or deforming the seal housing.

Protect the sealing elements when passing the seal over keyways, splines or sharp shaft edges.

Lubrication requirements and installation orientation should follow the equipment manufacturer's instructions and the specific seal construction.

Frequently Asked Questions

What are the dimensions of CORTECO 19016512?

The seal measures 72x96x9 mm, with a 72 mm inside diameter, 96 mm outside diameter and 9 mm width.

What material is used?

The sealing material is VMQ, a silicone rubber elastomer.

What does LHTC mean?

LHTC is the seal construction profile designation. Its detailed geometry should be verified using the manufacturer's technical documentation.

Is VMQ silicone rubber?

Yes. VMQ identifies a group of silicone rubber elastomers used in technical sealing applications.

Is a VMQ oil seal resistant to high temperatures?

VMQ generally offers good resistance to elevated temperatures, but the permissible temperature range of this particular seal must be confirmed.

Can CORTECO 19016512 be replaced with an NBR oil seal?

Not automatically. VMQ and NBR have different material properties and are not interchangeable in every application.

Can an FKM oil seal with the same dimensions be used instead?

Only after confirming material compatibility, construction requirements and equipment operating conditions.

Does this oil seal have an additional dust lip?

The exact number and arrangement of sealing lips for CORTECO 19016512 require confirmation from the manufacturer's technical drawing.

Does the seal have a garter spring?

The presence of a garter spring should not be confirmed solely from the supplied designation without product-specific construction documentation.

Is VMQ suitable for mineral oils?

Compatibility depends on the specific silicone compound, oil formulation and operating conditions. It must be verified for the intended application.

Is this seal suitable for a specific vehicle or machine?

Compatibility must be confirmed using the original equipment part reference and technical documentation.

Can any 72x96x9 mm oil seal replace this product?

No. The VMQ material, LHTC profile and construction requirements must also be considered.
