High Temperature O Rings Silicone Customized , Waterproof O Rings
For Auto Seals
Drawing of O ring:
This drawing will give you a concept of what o ring looks like.
Silicone o rings are widely used in industry and there are multiple
formulations. Silicone rubbers are often one or two part polymers,
and may contain fillers to improve properties or reduce cost.
Silicone rubber is generally non-reactive, stable, and resistant to
extreme environments and temperatures from -40 °C to +220 °C while
still maintaining its useful properties. Due to these properties
and its ease of manufacturing and shaping, silicone rubber is used
in silicone gaskets, seals and orings and can be found in a wide
variety of products such as:
- Automotive applications
- Many cooking, baking, and food storage products
- Apparel including undergarments, sportswear, and footwear
- Electronics equipment
- Home repair and hardware
- A host of unseen applications.
Silicone’s temperature tolerance maintains a lack of brittleness
below freezing and excellent tolerance of temperatures in excess of
150 °C (302 °F).
Silicone o rings, gaskets and seals are Resistant To: High/Dry Heat, Fungus, Sunlight, Ozone, and Weathering.
Do not use with: Fuels, silicone, and petroleum based oils, acids

ASTM D1418 Designation: MQ, PMQ, VMQ, PVMQ
ASTM D2000/SAE J200 Type, Class: FC, FE, GE
Apple Compound Designation: SL
Standard Color: Red
Key Use(s): Static seals in extreme temperature situations. Seals for medical
devices, compatible with FDA regulations.
Standard Compound: -40° to +220°C
Hardness (Shore A): 10 to 85
Features: Phenyl (PVMQ) based silicones can perform to -85°F. New polymers
can take short term to 600°F.
Limitations: Generally, low abrasion and tear resistance, and high friction
characteristics preclude silicones from effectively sealing some
dynamic applications. Silicones are also highly permeable to gases
and are generally not recommended for exposure to ketones
(MEK,acetone) or concentrated acids.
