Customized High and Low Temperature Rubber Food Grade Sealing Gasket Silicone O Ring
Features
At their cross-section, most O-rings are disc-shape. Users place the O-ring within a groove between two joints, where, when pressured, its disc-shaped cross-section is compressed and deforms. When this happens, the O-ring creates a seal. The more pressure is applied inside or outside the O-ring, the stronger the seal becomes. The sealing capabilities of an O-ring, however, are not based on how well it deforms. Rather, they are based on its resilience, which is measured by its ability to hold its original shape after deformation.
Types
Silicone O-Ring
Silicone lends its support to applications that require a material high in resistance to fast, wide temperature swings, extreme dry heat and UV weathering. Typically, they're used in the heating and medical industries. However, because silicone is so expensive, silicone O-rings are also sometimes used around earplugs and as necklace strings.
EPDM O-Ring
O-ring EPDM types are extremely resistant to alcohol, acetone and polar solvents like MEK. However, they do have poor resistance to petroleum oils and greases. Most often, they are used with solvents.
Neoprene O-Ring
Heat exchangers and chiller systems rely on neoprene O-rings to seal refrigerants, like Freon, inside.
FKM O-Ring
FKM O-rings are useful in processes similar to other rubber O-rings, such as oil refining and chemical processing, because they are chemical resistant and have an extremely high process temperature limit.
Nitrile O-Ring
Of all the standard O-ring products, nitrile O-rings are the most popular. They are regarded for their oil and fuel resistance.
Clear O-Ring
Clear plastic O-rings are used routinely in hospitals and medical care centers, for IVs and other clear tubing. They are also common in food and beverage processing. Typically made from polyurethane or silicone, they can be ultra-clear or semi-clear, depending on your needs.
Metal O-Ring
Rubber O-rings are not universally temperature resistant without additives, which is why manufacturers sometimes also use metal O-rings or metal alloyed O-rings. Metal O-rings are generally stronger and more resistant to other stresses as well, like corrosion. They are used with applications that have a wider range process range, temperature range and/or corrosion range.
Metric O-Ring
Metric O-rings are O-rings with measurements specified using the metric system. Most O-rings outside of the US, including global O-rings, use metric O-ring measurements.
O-Ring Cord
O-ring cord is an O-ring product sold by the foot. With it, you can slice the material yourself, creating any O-ring size for a quick seal whenever you need it. They work best with large diameter, static applications.
Oil Seal Gasket
An oil seal O-ring gasket is designed to do three main things: 1) keep contaminants from seeping into any static or dynamic machinery 2) keep lubricant inside the equipment 3) keep fluids, like oil and water, from mixing
