Application Scenarios of O-rings

Silicone O-rings are widely used in automobiles, machinery, electrical appliances, cylinders, bearings, pumps, water pipes, valves, doors and windows, chemical pipelines and other scenarios.

The most typical application of silicone rubber O-rings is in the field of household appliances, especially products that are in direct contact with food. This is due to the thermal insulation and electrical insulation properties of silicone.

Properties of Silicone Rubber O-Rings

Its main functions are hole seals, oil seals, water seals, dust seals, fixed seals, shaft seals, and rotary seals.

Tolerates: extreme temperatures, corrosion resistance, wear resistance, against fungal growth, UV and ozone exposure, resistance to weathering, resistance to animal and vegetable oils and other oils.
Excellent compression resistance, flexibility, electrical insulation.

Which o-ring material is right for you?

When you’re choosing an O-ring for your project, it’s important to keep in mind the different factors that affect o-ring materials. These factors include:

• Application of O-rings
• The pressure the o-ring will be subjected to
• The temperature the o-ring will withstand
• Fastener size
• Sealed medium

Each of these factors has an impact on the performance of the O-ring. Not all O-ring materials are effective in all environments, and what works in one application may not work in another.Silicone rubber O-rings are the most popular material choice because of their ability to operate over a wide temperature range without melting or hardening.
