Blue Red Good Electrical Insulation O Seal Silicone Small Rubber O Rings Manufacturer


Introduction for O Rings


Measurement of O Ring

Blue Red Good Electrical Insulation O Seal Silicone Small Rubber O Rings Manufacturer 0



O-Ring is a simple and versatile ring-shaped packing or sealing device with a circular

cross section. The opposite side of an O Ring are squeezed between the walls of the

cavity or gland into which the O -Ring is installed. The zero clearance within the gland

provides an effective sealing and blocking the flow of liquids, and gases through the

glands. Internal pressure dynamics and static.

O-rings are available in a variety of materials, in both standard and custom sizes. Our

proprietary compounds are designed to perform in a wide range of applications with

varying chemical exposures, pressures and temperatures.

*Service Temperature
For Silicones the service temperatures are from -60 C to 225 C. Some special types can be used in

extreme temperature up to 300 C and down to -100 C.

Silicone rubber performs well under environmental and temperature extremes. It is usually applied in

automotive and aerospace industries where flexibility and longevity are important. It is also a suitable

material for parts that need FDA approval for food handling equipment and appliances.




The below is the 


Material Temperature Characteristics Application
NR -50~80℃ Good elasticity, tensile strength, wear resistance Tires, cushions, seals, cable insulation sleeves
NBR -40~120℃ Oil resistance, wear resistance, high temperature and aging resistance Oil resistant seals, diaphragms, hose and soft tubing
SIL/VMQ -60~250℃ High and low temperature resistance, non-toxic tasteless, aging resistance, insulation resistance, good thermal conductivity Household articles, seals, shock absorbers, electronic accessories
EPDM -40~150℃ Weather resistance, ozone aging resistance, steam resistance, strong acid and alkali resistance Phosphate hydraulic oil system seals, hose and auto parts
FKM/FPM -40~240℃ High temperature resistance, oil,chemical,aging resistance, good insulation, flame-retardant, less
