Detail Information

Product Introduction

Silicone O Rings and rubber gaskets are among the most widely used sealing components in modern engineering and manufacturing. Produced by experienced silicone rubber gasket manufacturers, these precision-engineered parts play a critical role in ensuring airtight and watertight seals across diverse industries such as automotive, medical devices, home appliances, and industrial equipment.

1. What Are Silicone O Rings and Silicone Rubber Gaskets?

A silicone O Ring is a circular elastomer sealing element designed to prevent the passage of liquids or gases between two surfaces. It is commonly used in pumps, valves, engines, and fluid handling systems.

A silicone gasket, in contrast, is generally flat and used to create a larger sealing surface between flanges, casings, or housings. Both are manufactured from high-quality silicone rubber, offering excellent resilience, flexibility, and biocompatibility. Depending on customer needs, options include medical grade, food grade, and high-temperature resistant silicone.

2. Working Principle of Silicone O Rings – Especially Soft Silicone O Rings

The fundamental principle behind O Ring sealing lies in compression and elasticity. When installed, the O Ring is slightly compressed between two contact surfaces. Under pressure, it expands and fills micro-gaps, effectively preventing leakage.

Soft silicone O Rings are specifically designed for low-pressure and precision environments. Their softer material composition allows superior adaptability, making them ideal for medical devices such as ventilator connectors, infusion pumps, and diagnostic equipment, as well as home appliances like coffee machines, water purifiers, and kitchen devices.

3. Key Properties of Silicone Rubber O Rings & Gaskets

Wide Temperature Resistance: Functional from -60°C up to +230°C, ensuring durability in both extreme cold and heat.

Excellent Chemical Resistance: Resistant to water, oils, mild acids, and many cleaning agents, making them suitable for medical and household use.

Superior Elasticity and Flexibility: Even after prolonged compression, silicone O Rings maintain their sealing performance without permanent deformation.

Safety & Compliance: Available in FDA-approved, LFGB, and ISO-certified medical-grade silicone, ensuring safety in direct contact with food, medical fluids, or human skin.

Longevity & Cost Efficiency: Silicone seals offer long service life, reducing maintenance costs and minimizing downtime.

Application Fields

Automotive Industry: Engine seals, headlight gaskets, vibration-damping components.

Medical Devices: Ventilator seals, syringe pump gaskets, laboratory diagnostic equipment.

Home Appliances: Coffee makers, water dispensers, dishwashers, and kitchen equipment.

General Industry: Valves, pumps, and precision fluid control systems.
