Encapsulated O-Rings: What They Are and Where They’re Used

Encapsulated o-rings are specialty seals designed for use in applications where high temperature and corrosive conditions make the use of traditional elastomer o-rings infeasible.

The o-rings are comprised of two parts: a rubber inner core, which provides compression and elasticity, and a thin outer jacket made from Teflon®, which gives the seal high corrosion resistance and thermal stability. They are widely used in chemical, petrochemical, food, and pharmaceutical processes, where seals are required to perform reliably in extremely harsh environments.

Video: O-Ring Sizing Tools

For accurate o-ring sizing, use these tools which can all be purchased on the Global O-Ring and Seal website.

  • Laminated O-Ring Size Chart – An easy to use flip chart showing silhouettes of 239 different sizes of O-Rings. Simply place the o-ring on the chart to match the correct size.
  • O-Ring Sizing Cone – This O-Ring Cone measures 184 of the most popular size O-Rings from ¼” ID to 5-5/8″ ID in five standard cross sections (.070″, .103″, .139″, .210″, and .275″). This cone will provide the user with O-Ring dash numbers instantly. Just slip the O-Ring into the proper slot to determine the cross section. Then place the O-Ring onto the cone and adjust to the proper step to determine the AS568 size dash number above the slot.
  • Gauge – Slide gauge for measuring standard cross section o-rings with an inside diameter up to 13″.
  • Digital Caliper – A preferred tool for precise measurement, our sliding caliper can measure the diameter and length of many components – not just o-rings.
  • O-Sizer Tape – This specially designed o-ring measuring tape comes in three different sizes and is used to measure the ID of metric and AS568 o-rings up to 26 inches.
  • Pi-Tape – Our precision engineered pi-tapes are the most precise tool for measuring the inside diameter of an o-ring to the thousandths of an inch. We offer several different sizes of pi-tapes, depending on the ID size needing to be measured.

An Introduction to Metal Detectable O-Rings

Over time, exposure to extreme temperatures, continuous vibration, and corrosive clean-in-place (CIP) chemicals can cause o-rings in industrial processing operations to fail. When this occurs, fragments of rubber from seals and gaskets can shear off and migrate through sanitary systems to enter the product stream. In many processes, this issue requires little more than a short stoppage to replace the o-ring. However, in food, beverage, and pharmaceutical processing operations, where the end-product is meant for human consumption and quality is tightly regulated, it can be much more problematic.

What is An O-Ring?

According to the Oxford Dictionary, an o-ring is a round gasket that can contain a circular cross section which is often made of pliable material (rubber, plastic, etc.) that is used to create a tight seal in connections for pipes, valves, tubes, inlets, outlets, and much more. O-rings are one of the most common industry-used seals in machine design. This is because they are easy to make, cost effective, reliable, and are easy to install in many cases. O-rings can be designed and fabricated to operate in many conditions such as high or low temperature, under varying pressures, and for various media (the material flowing adjacent to the seal).

Save Time and Money with Shaft Repair Sleeves

At a certain point in the life of a crankshaft seal, technicians find the wear so severe that oil leaks are likely to occur even after the installation of a new replacement seal. Until recently, the only way to address the issue was to either re-machine the surface of the crankshaft or replace it entirely. Both of these options are time intensive and come with a hefty cost. However, Global O-Ring offers a superb alternative: the shaft repair sleeve. Continue reading “Save Time and Money with Shaft Repair Sleeves”

O-Rings for Rapid Gas Decompression‏

What is Rapid Gas Decompression?

Rapid Gas Decompression (RGD) is also commonly referred to as Explosive Decompression (ED) and is a phenomenon found in many high pressure processes. It occurs when a pressurized gas is released very quickly and can cause the rubber seals inside the piece of equipment to fail. This seal damage is not always visible because small bubbles form on the inside of the rubber seal, which can lead to seal failure. Certain o-ring compounds have been specifically formulated to resist this type of failure and withstand rapid gas decompression. These types of o-rings are commonly referred to as RGD, ED Resistant, or AED (anti-explosive decompression) o-rings.

History of the Vulcanization of Rubber

About Natural Rubber

You might be surprised to know that the rubber in your tires and so many other modern uses begins as a white, liquid type substance called latex that is derived from certain plants. If you cut a dandelion stem, for instance, you’ll see latex dripping from the stem. Theoretically, rubber could be made by growing dandelions, though considering the amount of rubber used in the world today, half the globe would have to be dandelion farms. There are approximately 200 plants in the world that could supply latex, though the source of over 99 percent of the natural rubber currently produced comes from the Hevea brasiliensis tree, or the rubber tree.
