Silicone O-Ring MVQ/VMQ 15x2

Overview

Silicone O-Ring MVQ/VMQ 15x2 100 pcs is a package of 100 GRN sealing rings with a 15 mm inside diameter and 2 mm circular cross-section. The O-rings are manufactured from VMQ silicone rubber, also searched commercially as MVQ. Silicone is selected for industrial sealing where temperature flexibility, resistance to ageing and stable elastomer properties are more important than the characteristics offered by standard NBR.

Industrial Applications

Silicone O-Ring 15x2 can be used in appropriately designed sealing points in technical equipment, covers, housings, instrumentation and industrial assemblies. VMQ is particularly relevant for equipment exposed to elevated or low temperatures and environmental ageing. Compatibility with the actual process fluid must be verified before using VMQ as an OEM replacement or alternative to another elastomer.

Construction

The seal is a one-piece elastomer ring with a 2 mm circular cross-section. It has no sealing lip, garter spring or separate dust lip. Sealing is generated by controlled compression inside a correctly dimensioned groove. Pressure capability depends on groove geometry, extrusion gap, material hardness and actual operating conditions.

Material

VMQ, Vinyl Methyl Silicone Rubber, is a silicone elastomer known for temperature flexibility and resistance to ozone, weathering and ageing. VMQ has different mechanical and chemical characteristics from NBR, FKM and EPDM, so identical dimensions do not make these materials automatically interchangeable. Temperature limits should be based on the specification of the actual silicone compound.

Why Industrial Buyers Choose This Product

Silicone O-Ring MVQ/VMQ 15x2 provides a material option for maintenance stock, industrial service, machine rebuilding and production support where silicone properties are specified. The 100-piece package provides practical technical inventory. For OEM replacement or fleet maintenance, buyers should verify dimensions, compound, hardness, medium compatibility and operating temperature against the original seal specification.

Operational Advantages

• VMQ retains useful flexibility across a broad temperature range.
• 15x2 mm dimensions provide clear dimensional identification.
• Silicone offers good resistance to ozone and atmospheric ageing.
• Circular geometry provides sealing through controlled groove compression.
• 100-piece packaging supports maintenance and production inventory.
• One-piece construction simplifies storage and replacement during industrial service.

FAQ

What does the Silicone O-Ring 15x2 size mean?

15 mm is the nominal inside diameter, while 2 mm is the diameter of the circular cross-section.

What is the correct material designation, VMQ or MVQ?

VMQ is the commonly standardized abbreviation for vinyl methyl silicone rubber. MVQ is also encountered commercially, which is why both terms can be useful for product identification and search.

What is the outside diameter of a 15x2 O-ring?

The nominal outside diameter is 19 mm, calculated as 15 + 2 x 2 = 19 mm. The product size designation remains 15x2.

Can a VMQ 15x2 O-ring replace an NBR 15x2 O-ring?

Not automatically. VMQ and NBR have different mechanical, chemical and temperature characteristics, so the required elastomer must be verified for the application.

How many silicone O-rings are included?

The package contains 100 Silicone O-Rings MVQ/VMQ 15x2 with the same nominal specification.
