VMQ Silicone O Ring Performance
Elastic Recovery
The silicone compound provides elastic recovery after controlled compression, helping the O Ring maintain contact with mating surfaces.
Weather & Ozone Resistance
VMQ offers resistance to ozone and outdoor environmental exposure, supporting applications subject to weathering and atmospheric conditions.
Temperature Adaptability
Silicone maintains useful flexibility across changing temperature conditions, with the applicable range
depending on the selected compound and service environment.
Compression Set Control
Proper compound selection and compression conditions can help limit permanent deformation after prolonged compression, supporting the retention of the O Ring's sealing profile.
Custom Silicone O Ring Development

Chaoyue supports custom VMQ O Ring development for applications requiring specifications beyond standard silicone sealing components. Product development can be based on drawings, samples, or mating-component information.
- Compound & Hardness Selection - Silicone formulation and Shore A hardness can be considered according to temperature, flexibility, compression, and environmental requirements.
- Application-Specific Geometry - Non-standard dimensions, cross-sections, profiles, and identification colors can be developed around the customer's assembly.
- Prototype to Batch Production - Supports sample evaluation, mold development, specification approval, and subsequent batch production according to project requirements.
FAQ
How should VMQ Silicone O Rings be stored before assembly?
Silicone O Rings should be kept clean and dry, protected from direct sunlight, excessive heat, ozone-generating equipment, and mechanical deformation. Keeping them in suitable packaging can help preserve their original condition before installation.
Can silicone O Rings be supplied with different identification colors?
Yes. Different colors can be discussed for part identification, product differentiation, or assembly management, subject to the selected silicone compound and color requirements.
Can VMQ O Rings be supplied with individual part numbers?
Yes. Part numbers, labels, batch identification, or other marking and packaging requirements can be arranged according to the customer's inventory and traceability system.
