O-ring rubber, rubber gasket, oring gasket is a common name for o-ring washers used mainly for sealing in flanges, couplings, hydraulic cylinders, fittings, water pipes. etc., the o-ring seal has capabilities such as resistance to oil, heat or other dangerous chemicals depending on the material that makes up the o-ring, rubber gasket.
Rubber o-ring construction materials, rubber gaskets can be made from many different types of materials such as: NBA rubber, neoprene, heat-resistant silicone rubber, Neoprene or some types of rubber o-ring gaskets, Rubber cushions that need to withstand extreme conditions such as high temperatures, chemicals, abrasion…etc are specially made from FKM at a higher cost.

Hardness of rubber o-rings: Can range from 40 shore A to 80 shore depending on the material and manufacturing process.
Product thickness: Depending on the customer’s request, it can be from D2 to D300.
Technical requirements: Rubber O-rings can have characteristics such as heat resistance, chemical resistance, abrasion resistance…etc, depending on the product’s use.
So what are rubber o-rings, rubber cushions usually used for?
We can see rubber o-rings, rubber gaskets are used in products used in the food processing industry and, this type of rubber o-rings are usually made of silicon and are often in direct contact. With food, such as beverage lids, canned foods, or in sealed food containers, these gaskets come in a variety of shapes, clear, rectangular, or square, and typically this product usually has a hollow inside to ensure elasticity and tightness when closing the lid, the materials that make up these rubber o-rings must meet food safety regulations.

In the medical field, rubber o-rings are used a lot to make products such as capping drug products, making syringes, surgical instruments, etc.
rubber o-ring products have characteristics such as user safety, high level of detail finishing, odorless and can be colored according to usage requirements.
Last and most common are rubber o-rings used in the machine parts of industrial machinery, in cars and motorcycles, in electrical products, or in pipelines. water, gas or other chemical pipelines…etc
Along with the development of science and technology of rubber O-ring products, rubber gaskets are being developed more and more improved in terms of technical characteristics and product quality, as well as can be used for different applications. used for many different purposes to create many quality products for human life.
