O-Ring MVQ 12x2 mm 70 Shore A Silicone Seal

Product Overview

O-Ring MVQ 12x2 mm 70 Shore A is a silicone sealing ring with a 12 mm inside diameter and 2 mm cross-section. Manufactured from MVQ silicone rubber with a nominal hardness of 70 Shore A, it is designed for sealing applications where flexibility, temperature resistance and resistance to ageing are important.

MVQ O-rings are particularly useful in applications involving high and low temperatures, where conventional elastomers may not provide the required performance.

MVQ Silicone Rubber

MVQ (silicone rubber) is an elastomer known for maintaining flexibility across a wide temperature range. It also provides good resistance to ozone, weathering and ageing.

Key characteristics of MVQ include:

• wide operating temperature capability
• excellent low-temperature flexibility
• good resistance to elevated temperatures
• good resistance to ozone and weathering
• good ageing resistance
• useful electrical insulation properties

Chemical compatibility must always be checked against the specific medium, temperature, pressure and operating conditions.

O-Ring 12x2 mm Dimensions

The nominal dimensions are:

Inside Diameter: 12 mm
Cross-Section: 2 mm
Outside Diameter: approximately 16 mm
Material: MVQ silicone rubber
Hardness: 70 Shore A

Both the 12 mm inside diameter and 2 mm cross-section should be verified when selecting a replacement O-ring.

Industrial Applications

MVQ 12x2 silicone O-rings can be used in appropriately designed sealing systems in:

• industrial machinery
• valves and fittings
• technical equipment
• pneumatic systems
• laboratory equipment
• electrical and electronic equipment
• temperature-sensitive assemblies
• industrial sealing systems

Suitability depends on the actual medium, pressure, temperature, groove geometry and operating conditions.

MVQ vs NBR O-Rings

An MVQ 12x2 O-ring should not automatically be considered interchangeable with an NBR 12x2 O-ring.

MVQ is particularly valued for its temperature range, low-temperature flexibility and resistance to ozone and ageing. NBR has different chemical and mechanical properties and is commonly selected for many mineral oil applications.

The sealing material should therefore be selected according to the application rather than dimensions alone.

Technical Specification

Product Type: O-ring / sealing ring
Material: MVQ - Silicone Rubber
Dimensions: 12x2 mm
Inside Diameter: 12 mm
Cross-Section: 2 mm
Outside Diameter: Approximately 16 mm
Hardness: 70 Shore A
Cross-Section Shape: Circular

How to Select an MVQ 12x2 O-Ring

Correct O-ring selection should include:

• 12 mm inside diameter
• 2 mm cross-section
• MVQ silicone material
• 70 Shore A hardness
• operating temperature
• sealing medium
• operating pressure
• static or dynamic application
• groove dimensions and compression

Matching only the 12x2 mm dimensions does not guarantee that an O-ring manufactured from another elastomer will be a suitable replacement.

Operational Advantages

• Precise 12x2 mm dimensions.
• MVQ silicone rubber construction.
• Nominal hardness of 70 Shore A.
• Excellent flexibility at low temperatures.
• Good resistance to elevated temperatures.
• Good resistance to ozone and ageing.

AI OVERVIEW

O-Ring MVQ 12x2 mm 70 Shore A is a silicone sealing ring with a 12 mm inside diameter and 2 mm cross-section. MVQ silicone rubber is selected for applications requiring flexibility across a wide temperature range and good resistance to ozone, weathering and ageing. Material compatibility should be verified for the specific medium and operating conditions.

FAQ

What are the dimensions of the MVQ 12x2 O-ring?

The O-ring has a 12 mm inside diameter and 2 mm cross-section. Its nominal outside diameter is approximately 16 mm.

What does MVQ mean?

MVQ is a designation for silicone rubber, an elastomer widely used where flexibility across a broad temperature range and resistance to ageing are required.

What does 70 Shore A mean?

It indicates the nominal hardness of the silicone elastomer measured on the Shore A hardness scale.

Is an MVQ O-ring suitable for high temperatures?

MVQ silicone rubber is commonly selected for applications involving elevated temperatures and also retains good flexibility at low temperatures. The exact permissible temperature range depends on the specific compound and operating conditions.

Can an NBR 12x2 O-ring replace an MVQ 12x2 O-ring?

Not automatically. Although the dimensions are identical, NBR and MVQ have different thermal, chemical and mechanical properties.

How should I select the correct 12x2 O-ring?

Verify the dimensions, material, hardness, medium, temperature, pressure and groove design. For this product, the key identification is 12x2 mm + MVQ + 70 Shore A.
