Product Instruction

Silicone O rings are circular seals set in cylindrical applications to prevent media passing through joints and other breaks in construction. These O-rings are cheap, easy to install, versatile, and have immense capacity to handle pressures. Thus, they prominently used in mechanical equipment.

These O-rings can be made from various materials which are dependent on its application. Silicone O-rings can handle pressure exerted by hydraulic cylinders over their seals. O-rings are used in various types of motionless or movable joints and piping. Silicone O-rings are extensively used in aerospace and automotive fields.

Features of O-Rings:

1) Silicone Rings comprise of two parts: a rubber based inner core for providing compression and elasticity along with a thin outer jacket made from Teflon which provides the seal thermal stability and corrosion resistance.

2) Depending on core material, O-rings are suitable for operating temperatures ranging from -95ºF to 450ºF.

3) Silicone O-Rings are resistant to most of the chemicals and retain their mechanical properties even after being exposed to high temperatures for a long time.

4) These O-rings have excellent dielectric properties, a low coefficient of friction, flexibility, toughness, and less to no moisture absorption property.

5) These O-rings have two core types: solid core and hollow core. Standard O-rings are supplied with either Viton/FKM/ silicone energizers. Silicone O-rings provide more flexibility in cold temperatures. Hollow core O-rings are used in fragile applications where more elasticity is required.

6) Silicone rings have an outer jacket which can be made up from either fluorinated ethylene propylene (FEP) or perfluoroalkoxy copolymer (PFA). FEP offers protection against various chemicals and has a low coefficient friction and low compression set. PFA provides additional benefits like it has higher mechanical strength and it can resist stress and cracking. Thus, PFA jacketed O-rings can be used in applications which require higher thermal stability and durability.

7) These O-rings are resistant towards UV radiation, ozone, and hot air.

8) Silicone O Rings are resistant towards fungus.

9) These O-Rings are odorless and non-toxic as silicone compounds are clean. These silicone O-rings are used in food, medical, and semi-conductor applications.

10) These O-rings are often used in fuel systems when temperature is very low.

Exactsilicone supplies O-rings which are made from extruded silicone cord, strip, and complex shaped profile, made using vulcanizing technique. Thus, these silicone O-rings have smooth joints. We also mold or custom silicone O rings as per client’s re
