O-ring 11x2 VMQ - Silicone Sealing Ring

Product Description

O-ring 11x2 MVQ 70 ShA - 100 pcs. is a silicone sealing ring with an inside diameter of 11 mm, a cross-sectional diameter of 2 mm and a nominal outside diameter of 15 mm. Manufactured from MVQ silicone rubber with a nominal hardness of 70 Shore A, it is designed for sealing connections in appropriately designed grooves.

MVQ silicone rubber offers good flexibility across a wide temperature range, excellent resistance to ozone and UV radiation, and good resistance to atmospheric ageing.

Silicone O-rings are particularly suitable for applications requiring stable elastomer properties under varying temperature conditions.

Each package contains 100 O-rings of the same dimensions and nominal hardness.

The nominal outside diameter is calculated as 11 mm + 2 x 2 mm = 15 mm.

MVQ Silicone Rubber - Material Properties

MVQ is a silicone-based elastomer commonly used in technical sealing applications. Its main advantage is its ability to maintain flexibility and sealing properties across a broad temperature range.

Key properties of MVQ silicone rubber include:

• Good resistance to high and low temperatures.

• Excellent resistance to ozone.

• Excellent resistance to ultraviolet radiation.

• Good resistance to atmospheric ageing.

• Good electrical insulation properties.

• Flexibility across a wide temperature range.

• Generally lower abrasion and tear resistance compared with many NBR rubber compounds.

Important: MVQ silicone rubber is not universally resistant to all oils, fuels, solvents or chemicals. Material compatibility must be verified for the specific operating medium, temperature and application.

The exact operating temperature range depends on the silicone compound and should be confirmed using the manufacturer's technical documentation.

O-ring Construction and Sealing Principle

The O-ring 11x2 MVQ 70 ShA features a continuous circular shape with a round cross-section.

When installed in a correctly dimensioned groove and compressed between mating surfaces, the elastomer deforms to create a sealing barrier that helps prevent leakage.

Sealing performance depends on several factors:

• Correct selection of O-ring and groove dimensions.

• Appropriate cross-sectional compression.

• Surface finish of mating components.

• Operating pressure.

• Operating temperature.

• Chemical compatibility with the sealing medium.

• Installation and operating conditions.

Proper groove design and installation are essential for maintaining reliable sealing performance.

Applications of Silicone O-ring 11x2

MVQ silicone O-rings are used in industrial and technical equipment where temperature resistance, flexibility and resistance to environmental ageing are important.

Typical applications may include:

• Static sealing connections in industrial machinery.

• Heating and thermal equipment.

• Electrical and electronic equipment housings.

• Components exposed to ozone and UV radiation.

• Technical assemblies requiring silicone elastomer seals.

• Selected pneumatic systems operating within the material's capabilities.

Suitability for a particular application depends on operating conditions and compatibility with the sealing medium.

Applications involving food contact, drinking water or medical equipment require appropriate certification or declarations of compliance for the specific product. The MVQ material designation alone does not confirm such approvals.

Installation and Operating Recommendations

Before installing the O-ring 11x2 MVQ 70 ShA, ensure that the sealing groove and mating surfaces are clean and free from sharp edges, burrs or contamination.

During installation:

• Avoid excessive stretching or twisting.

• Protect the O-ring from sharp edges and mechanical damage.

• Verify that the groove dimensions are suitable.

• Use only installation lubricants compatible with MVQ silicone rubber.

• Ensure that the O-ring is correctly positioned before assembly.

Due to the mechanical characteristics of silicone rubber, MVQ O-rings are generally better suited to appropriately designed static sealing applications than to applications involving intensive dynamic movement.

Incorrect installation, excessive compression or unsuitable operating conditions may reduce sealing effectiveness and service life.

FAQ - Frequently Asked Questions

What are the dimensions of O-ring 11x2 MVQ 70 ShA?

The O-ring has an inside diameter of 11 mm, a cross-sectional diameter of 2 mm and a nominal outside diameter of 15 mm.

What does MVQ mean?

MVQ is a designation for silicone rubber, an elastomer used in technical sealing applications because of its temperature resistance, flexibility and resistance to environmental ageing.

What does 70 ShA mean?

70 ShA indicates a nominal material hardness of 70 units on the Shore A scale, which measures the indentation hardness of elastomers.

Is the O-ring 11x2 MVQ resistant to high temperatures?

MVQ silicone rubber generally provides good resistance to elevated temperatures. The exact permissible temperature range depends on the specific silicone compound and operating conditions.

Is silicone MVQ suitable for oil sealing applications?

Compatibility depends on the type of oil, its additives, operating temperature and the specific MVQ compound. Material compatibility should be verified before use.

Can this silicone O-ring be used in food processing equipment?

Only if the specific product has the required documentation confirming compliance with applicable food-contact regulations.

Is the O-ring suitable for dynamic sealing?

Silicone O-rings are generally more suitable for static applications because MVQ typically has lower abrasion and tear resistance than many other elastomers. Dynamic use requires careful application-specific evaluation.

How many O-rings are included in one package?

Each package contains 100 pieces of O-ring 11x2 MVQ 70 ShA.
