Before we go over types of materials, hardness, sizes and tolerances of O-rings lets talk about how the O-ring actually seals. 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. A seal may consist of more than one component, such as an O-ring and a backup ring, or possibly an O-ring and two backup rings. 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. These variables may include pressure of the system, surface finish of metal parts, O-ring stretch, and squeeze, etc. This means there’s a fairly uniform mechanical stress placed on all contacting surfaces of an o-ring. 5. 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. O-rings are the most frequently used of all seals. … To do this, they use a biomedical silicone o ring, which forms a perfect seal and keeps the new tooth safe. When compared with an O-ring, these other seal types may show one or more design disadvantages which might be overcome by use of an O-ring. There are a number of popular high-temperature o-ring material choices, including nitrile, hydrogenated nitrile, silicone rubber, polyacrylate and more. The seals used in rotating, reciprocating, or oscillating motion are known as dynamic seals. This seal prevents particle, vapour and fluid leakage to protect and maintain pressure whilst keeps debris out, ensuring proper function and safety. This includes O-rings, D-rings, back-up rings, cover seals and gaskets. In general, depending on a number of factors including grade of o-ring and precise application, the Viton® seal working temperature range is held to be between -26 C and +205 C, although they can withstand higher temperatures for short periods. There are any number of high-performance materials used in the production of o-rings, ranging from nitrile and silicone rubber to fluorocarbons, metals and more. Nitrile O-ring seals. Hydraulic seals used internally on a sliding or moving assembly are normally called packings. An oil seal used for sealing a rotating member is called a rotary seal. End cover seal. In this section, we’ll look a little more closely at what o-rings do, and some of the applications that they’re very often used for.

Performance of these seals is affected by various variables. Over time, repeating this process will start to have an effect on the resilience and uniformity of the materials and the torus shape of the seal, and ultimately the o-ring will need swapping out for a new one if the seal is to remain tight. The O-Ring sits in the middle of a gland when it’s at rest, but as pressure begins to rise in the sealing system, the O-Ring shifts to the opposite side of the pressure. Double “O” ring seals have been used for many years to provide an aseptic seal for glass electrodes in stainless steel housings in fermenters. Cold set must be avoided: In applications where cryogenic operations work alongside higher temperature operations, the risk of stresses on the o-ring being unable to relax at low temperatures is high when the wrong type of seal is used. For more detail on all types of O-ring materials and designated temperature ranges, feel free to contact our expert support team any time - they’ll be glad to offer further advice and assistance on specific high-temperature seals, materials and applications. O-rings are used primarily for sealing. It also forms a better seal than plastic. An O-ring is an internal part found on all plunger-system blasters. Know about Different Types of Static Seals. To ensure a proper working of these seals, it is important that you source them from a reliable manufacturer. Therefore, the best O-Ring material is the material best-suited for the application. Common types of external seals The types of seals most commonly used with rolling (ball and roller) bearings are contact or lip seals; non-contact seals; and, to a lesser degree, various types of bearing isolators that combine the functions of contact and non-contact seals in different ways. They are usually non-metallic, quite soft rings placed in a housing, or arranged in a mixture of rings creating a sealing unit. Glide ring seal with an O-ring energizer for light- to medium-duty applications, made of hard grade polyurethane and an NBR O-ring. In this section, we’ll take a quick look at the various different o-ring material types. The resulting o-ring seal is both economical and reliable, as well as relatively resilient and easy to maintain/replace when needed. More information, including design criteria on O-ring … They possess a circular cross-section which works as a seal both in static and dynamic applications, being compressed amid mating surfaces within walls of the gland into which they are installed. In the UK, this applies to natural and synthetic rubbers, elastomers and polymers. What is the Difference between Static and Dynamic O-rings? They offer good resistance to high temperatures (up to 210 C), but are prone to failure below -15 C in dynamic applications when they tend to become too stiff and inflexible. Over time and in certain industries, specific o-ring colors have been used to differentiate between materials. O-ring rubber seals are available in a very wide range of gasket and o-ring types, including natural rubber as well as a large array of other elastomer and compound products. Phosphate ester hydraulic fluids, brake fluids and halogenated hydrocarbons are damaging to nitrile, and it’s not the best choice for high temperature or pressure demands, The nitrile o-ring temperature range is usually anywhere from -50 C to 120 C. Rubber o-rings are perhaps the most common type, serving an enormous array of purposes and functions in less specific or demanding applications than some of the higher-tech variants seen in heavy industrial environments. Resistance to petroleum oils, acids, silicone fluids is good, and Viton® is highly resistant to oxidation, UV damage, fungus, ozone, oils, and petroleum-based lubricants. This is known as the secondary seal and may be an o -ring as shown, a v -ring, a wedge or any similar sealing ring. Importance of FDA Approved O-Rings in F&B and Pharmaceutical Industries. [Figure 1] Hydraulic seals used between nonmoving fittings … O-Ring Colors. The point of the seal is to keep the air in, and push it out the other side, which increases performance. Paintballing: Paintball guns use compressed air to shoot globs of paint at unsuspecting enemies. Phelps carries a wide range of O'rings for various fluid sealing applications. Oil seals are used to protect shafts and bearings from ingress of … We supply Hydraulic & Pneumatic seals for single and double acting cylinders, composite piston seals, compact seals, independent wear rings, bonded seals, static seals (O Rings), and symmetrical seals. Silicone o-rings are very much a gasket/sealant industry standard today. For use as an anti-extrusion device in dynamic O-ring applications where there is high pressure or excessive gland clearance. A u-cup is an o-ring formed into a u-shaped channel. They’re commonly used due to the inherent resilience of stainless steel o-rings, which means seals can spring back promptly once pressure is reduced. The seal between the rotating member and shaft or shaft sleeve (4). Static Seal. The point of the seal is to keep the air in, and push it out the other side, which increases performance. Generally speaking, O-rings are used as static seals. Guide to Different Types of O-ring Applications, types of seals used in various dynamic, as well as static applications, Tips for Selecting the O-Ring Squeeze Ratio. O-ring seals for Flared Fittings come in two primary types that use O-ring face seals (ORFS): An ORFS fitting has a replaceable elastomeric O-ring held in a groove in the face of the fitting. Different types of dynamic movements - for example, rotary, reciprocating and oscillating - demand that o-rings be manufactured with different material qualities to perform to the optimal level. There are various types and arrangement of the mechanical seals being used for the centrifugal pumps. Basically an O-ring is used to block a pathway that fluid or air may escape through. Nitrile O-rings, which have a temperature range between -54 and 149 degrees Celsius, are suitable for use with water, petroleum oils and some hydraulic fluids. Our website uses cookies and similar technologies to provide you with a better service while searching or placing an order, for analytical purposes and to personalise our advertising to you.

Appropriate hardware configuration, durometer, and feet-per-minute values are important for a proper sealing. This catalog lists Koyo oil seals and O-rings, including all items of the dimension series specified in ISO, JIS and JASO (Japanese Automobile Standards Organization) standards. One of the simplest examples of a static seal is the O-ring. Nitrile O-ring seals. Seals prevent fluids from escaping through the gaps in mating pieces of hardware. It is a static seal to prevent hydraulic oil from leaking from the gap between the end cover and the cylinder wall. To keep the air sealed in and ensure a powerful shot, o rings are used throughout the gun. The base monomer or monomers is used to classify the type of rubber, for example: Nitrile, Silicone or Neoprene. A wide range of elastomers is available. O-Ring and Seal Material Guide for Oil and Gas Industry . Up to a point, this will create a tighter and tighter seal, but it’s vital not to put more stress on an o-ring than it’s designed to handle, as too much deformation will eventually cause the seal to start leaking again. An SEA J1452 ORFS is used in applications to reduce or eliminate leakage problems in … The more internal pressure is applied to this join, the more the o-ring is distorted inside its groove, which can improve its overall sealing force up to a point - but beyond a certain pressure, or under more dynamic workloads, this can cause failure of the seal. Known as ‘cold set’, this will create an unviable seal, leading to … A number of common seal types, T-Seals, U-Cups, V-Packing and other devices, have been, and are still used for both dynamic and static seals. ... (parts). This system is suitable for lower level hazards, provided that release of microorganisms is minimized and there are adequate disinfection procedures for dealing with leakages ( Werner, 1992 ).
