- O Rings
When assembled between two or more parts, an O-ring, also referred to as a toric seal, is a loop of elastomer with a round cross-section that is intended to be seated in a groove and squeezed to form a seal at the interface.
O-rings are among the most often used seals in machine design because they are affordable, simple to fabricate, dependable, and only need minimal mounting. Tens of megapascals of pressure can be sealed by them.
- O-ring Application:
O-rings may be utilized in applications that are static or dynamic and involve relative motion between the O-rings and the pieces. Rotating pump shafts and hydraulic cylinder pistons are two examples of dynamic objects.
Materials for rubber O-rings include NR, NBR, Neoprene, EPDM, Silicone, Viton and others. Here are a few examples of common O-rings produced from rubber material that are available.
NBR rubber O-ring:
Mineral oils, vegetable oils, aromatic hydrocarbons, petroleum oils, and many acids can all be used without damaging NBR (Nitrile) rubber. Moreover, it has adequate resilience, tensile, and compression set as well as good elongation qualities.
Silicone rubber O-ring:
Silicone rubber may be used with a wide range of acids and alkalis and is exceptionally chemically stable. It is resistant to oxidation, oil, ozone, UV light, high temperatures, and general weathering.
FKM (Viton) rubber O-ring:
FKM (Viton) rubber provides outstanding resistance to weathering, aging, chemical corrosion, oil, and flame. It maintains its mechanical qualities despite withstanding a wide range of corrosive fluids at high temperatures.
- Rubber Grommets
In general, rubber grommets are more frequently used to seal holes and shield cables and wires from edges and corners that could be sharp. Also, using rubber grommets instead of other types of grommets has various benefits.
