How To Know Types of Rubber Seals

You may have seen rubber seals almost anywhere. You just didn’t know that what you saw is another type of rubber seal. These rubber rings are commonly seen used for windows, for storage jars, for shower doors, and even for manufacturing purposes. Most people are fond of calling these seals rubber washers.

So, for information’s sake, isn’t it interesting to know the different types of rubber seals? You’ll surely be amazed to know that not rubber washers alone compose rubber seal varieties.

Learn the general rubber seal types, which are enumerated below:

  1. Oil Seal. Its name alone suggests that this common rubber seal is used to keep the oil in the container and prevent leaking. You can easily identify this type of seal because it usually comes with a flexible lip, rubbing against the container’s housing to provide better sealing of oil.
  2. Rubber O Rings. You will easily notice this seal type because they are in the class of o-rings. They are made from elastomer, a synthetic material similar to rubber. These are called Rubber O Rings because of their circular shape and round cross section. Usually, these are used for mechanical sealing.
  3. Rubber Hydraulic Seals. Just like the oil seals, the rubber hydraulic seals are especially made for hydraulic fluids. These are designed to bear the pressure and intense applications of industrial facilities that are using hydraulic fluids.
  4. Rubber Piston Seal. The special application of this seal is for better grip, making this common on bikes.
  5. Dynamic Seal. There are some machine components that in their functioning move relative to each other, although fluids still need to be sealed. But this motion causes leakage, and that is why a dynamic seal is used to stop the leaking.
  6. Lip Seal. This is perhaps the most flexible of rubber seals, making it useful for low-pressure and uniform sealing.
  7. Balanced Seal. This rubber seal is used in reducing the hydraulic pressure effects in seal compartments.
  8. Mechanical Seals. For manufacturers, these seals are very common, since these are specially created to survive high temperature, speed, and pressure.

Meanwhile, some seals are differentiated depending on their material make up. Thus, Teflon seals are made with Teflon materials and silicone seals are made out of silicone. Aside form the Teflon seals and silicone seals, other rubber seals named after the material used are the natural rubber seals, nitrile rubber seals, CSM seals, FKM seals, Butyl rubber seals, and styrene butadiene rubber seals.

See? There are many things you can learn from the simple rubber seals. But still, some people do not appreciate the usefulness of rubber seals. But actually, these magic seals are used in different industries including waste disposal, marine, aerospace, medical, pharmaceutical, automotive, nuclear, food, paper mills, and chemical processing. Meanwhile, machines that commonly need rubber seals are hydraulic cylinders, actuators, filters, engines, motors, lubricating systems, pumps, valves, and mechanical seals. But the most common applications where we see these everyday are for shower doors, for storage jars, and for windows.

The many uses of rubber seals with their various types make these simple yet useful things, humbly doing their purposes, ubiquitous in modern life. We may not notice their importance now, but the absence of a single rubber seal might hinder your world’s normal routine.
