High-temperature sealing o-rings are, as the name implies, designed to withstand extreme heat while continuing to provide a reliable seal between two surfaces or components.
This makes them ideal for demanding industries and environments such as oil and gas refineries, chemical processing, or any other scenario where a high-temperature seal is required, such as performance transport applications like turbo engines and aerospace engineering.
There are a number of popular high-temperature o-ring material choices, including nitrile, hydrogenated nitrile, silicone rubber, polyacrylate and more. Securing the best choice in any given scenario will generally be a balancing act between the specific operating temperature needed, and the most economical material option at that performance point.

Again, all industrial o-ring purchases should be carefully planned with direct reference to the specific role and environment the seal is required to perform in. However, as a rough guide to o-ring temperature rating and use limits, some of the more popular materials on sale generally operate within the following sorts of temperature ranges:
High-pressure resistance is a common requirement of industrial o-rings, along with reliable performance in high temperature and dynamic environments. For a high-pressure seal to work to optimal levels, o-ring design and manufacture again depends on choosing specific materials for better performance under specific conditions.
O-rings function on the principle that even pressure placed on the (more or less incompressible) o-ring material creates predictable deformation patterns around the perimeter of the gasket in its groove. This means there&#;s a fairly uniform mechanical stress placed on all contacting surfaces of an o-ring.
Provided the internal pressure from fluids being contained stays below a given O-ring's contact stress rating, it&#;s largely impossible for leaks to occur, even under high pressure. However, mechanical failure under high pressure can easily cause extrusion or destruction of the o-ring, which is why it&#;s important to choose the right material for the precise environment you&#;re looking to use it in.
An engine o-ring, especially one used in high performance or turbo engines, is a good example of a product that has to be rugged enough in design and material construction to handle various challenging requirements of temperature, pressure and chemical compatibility.
Many basic rubbers and polymers aren&#;t suitable for use with oils, fuels or solvent-based compounds. For use in an engine, an oil o-ring has to be created specifically from compatible hybrid materials that allow it to maintain crucial o-ring properties (flexibility, incompressibility) while offering more robust resistance to heat, pressure, o-ring leaking and chemical attack than a standard elastomer typically could.

Plumbing o-ring choices are widespread, given the range of materials, sizes and gauges available for use in ducting and pipework applications, as well as to form tight waterproof seals around taps and other fittings. Choosing the best product for the job depends on finding the correct size and shape for the specific role you have in mind.
Food-grade o-rings have been manufactured to more exacting standards of material composition, such that they&#;ve been officially declared &#;food safe&#; for use in the production and preparation of meals, beverages and dining products.
An approved food-grade o-ring must only consist of the material(s) declared and approved as food safety compliant in the country of manufacture/sale. In the UK, this applies to natural and synthetic rubbers, elastomers and polymers.
To achieve food grade approval, an o-ring manufacturer must also take into account extractable ingredients/compounds if the seal is to be used in direct contact with aqueous, acidic or fatty foods and drinks. Some common food-safe o-ring materials include EPDM, fluorocarbon, nitrile, neoprene and silicone.
Carbon dioxide often presents an issue for many types of o-rings, as softer materials have a tendency to absorb the gas over time and swell up. This can lead to an unreliable seal in the short term, and over time the CO2 will actually cause the o-ring to start to break down from within.
Some popular choices for use in applications where the o-ring will have extended CO2 contact include polyurethane, PTFE, nitrile, and fluoroelastomers. However, the best choice will always depend on the consideration of other environmental or application factors.
Aircraft o-rings and aerospace o-rings generally need to be highly chemically resistant, and able to operate within a wide range of temperatures and pressures in order to keep an aerospace craft&#;s powertrain running cleanly, efficiently and smoothly. Typical applications include fuel cap gaskets, fuel system o-rings, and valve cover seals.
Common elastomers for use in aerospace-type applications include nitriles, ethylene-propylene, fluorosilicones and more. Because there are so many different sizes and gauges of o-ring distributed throughout most aircraft engines and systems, most sales for aerospace and aeronautics are through bulk orders of multi-size o-ring kits.
In the world of industrial machinery, our attention often gravitates toward complex systems like intricate gears, advanced circuits, and high-tech control systems. Indeed, these elements are vital, but the success and efficiency of an industrial unit often hinge on simpler components, like o-rings. At Global O-Ring and Seal, we have always focused on these integral yet frequently overlooked components, acknowledging their pivotal role across numerous sectors. This comprehensive guide aims to deepen your understanding of the importance, usage, benefits, and selection of o-rings in the industrial landscape.
O-Rings might seem simple, but they serve an incredibly crucial function. Essentially, an o-ring is a loop of elastomer characterized by a round, or &#;o&#;-shaped, cross-section. It&#;s designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. This seemingly simple design, achieved through careful engineering, enables o-rings to withstand challenging environments, enduring harsh chemicals, extreme temperatures, and high pressures.
The structure of an o-ring is simple yet ingenious. Its round cross-section and the deformation it undergoes when compressed enables it to form an excellent seal, preventing gases or liquids from escaping. Let&#;s delve into the multifaceted significance of these sealing stalwarts.
O-Rings, though often hidden deep within the heart of machines, play an indispensable role in many industrial applications. Their primary function is to prevent the escape of gases or fluids, thus maintaining the integrity and operational efficiency of the systems they are part of.
Without o-rings, many industrial systems we rely on daily would fail. For instance, imagine a submarine grappling with high-pressure system failures or air conditioning units prone to refrigerant leaks. Worse yet, consider the catastrophic impact of a combustion engine failing due to improper sealing.
In each case, the robust and reliable o-rings stand guard, ensuring safe and efficient operation. Furthermore, o-rings also significantly contribute to industrial productivity. Any time lost due to leaks or malfunctions can cause substantial disruptions to output and performance. Therefore, the humble o-rings are the unsung heroes, forming the bedrock of efficient and uninterrupted operations in diverse industrial settings.
