Viton®O Rings have a working temperature range -15 to +200 degrees C. Viton®O Rings have good chemical resistance to mineral and synthetic oils and greases, engine and transmission oils, fuel and non-flammable hydraulic pressure fluids Viton®also has a very low gas permeability which makes it suitable for vacuum applications. Our range includes British Standard (BS1806), British […]
Shore Hardness or Durometer is one of several measures of the hardness of a material. Hardness may be defined as a material’s resistance to permanent indentation. The durometer scale was defined by Albert Ferdinand Shore who developed a device to measure Shore hardness in the 1920s. The term durometer is often used to refer to the measurement as […]
O-Ring Material Issues. Recently, we shared the three most common O-Ring design flaws. By identifying potential problems like insufficient gland volume, high tolerance levels and over compression, engineers can resolve potential O-Ring issues before they happen. Choosing the proper material is as crucial to the success of an O-Ring as the design. Key questions must be […]
O Ring History The first patent for the O-ring, is dated May 12, 1896 as a Swedish patent. J O Lundberg the inventor of the O-ring, received the patent. The US patent for the O-ring was filed in 1937 by a then 72-year-old Danish born machinist, Niels Christensen. Soon after emigrating to the USA in 1891, he patented […]
The global mechanical seals market is expected to grow at a CAGR of over 9% during the forecast period. The discovery of shale gas production also plays a significant role in boosting the demand for mechanical seals, as it has triggered oil production and exploration activities, especially in the US. Similarly, even modern hydrocarbon processing […]
Encapsulated O Rings Encapsulated O Rings are used in chemically aggressive environments. Depending on the core choice encapsulated either Silicone or Viton a working temperature range of -15 to +200 degrees C is achievable. Another advantage of FEP is that it has a very low coefficient of friction. Download Specs
Market News Global nitrile butadiene rubber market set for rapid growth, to reach around £346 million by 2020 according to a new research report. Nitrile-butadiene rubber is a complex family of various butadiene monomers and unsaturated copolymers. Its chemical and physical properties vary based on the polymer’s composition of nitrile. This form of synthetic rubber is […]
Oil Seals (rotary shaft seals) are available in metric and imperial sizes. The primary function of an oil seal is to protect and enhance the lifespan of bearing systems by retaining lubricants thereby reducing friction. It is possible to offer various sizes ranging from 6mm to 1000mm on the ID. The standard oil seal will […]
Because mechanical shaft seal failures are the number one cause of pump downtime, it was decided to dedicate this to mechanical seal basics. Years ago, most pump shafts were sealed using rings of soft packing, compressed by a packing gland, but this type of shaft seal required a fair amount of leakage just to lubricate […]
Main elements of a mechanical seals All mechanical seals are constructed with the following basic sets of parts: A set of (very flat) machined and lapped primary sealing faces: The very close (near) contact between these two flat mating surfaces, which are perpendicular to the shaft, minimizes leakage. Dissimilar materials are usually used for the […]

Rotary seals for abrasive, corrosive applications Rotary seals will never displace mechanical seals and conventional compression packing in all process applications. However, Gerry Morgansenior engineer Garlock Sealing Technologies argues they offer a better option in abrasive and corrosive environments. The process industries rely on numerous pumps to perform reliably to maintain plant productivity. To […]
Mechanical Seals enhanced plans result in release free, solid, longer-enduring pumps Since pumps move media through reactors, valves and channeling, they serve as “the heart” of any procedure in which they are put. Along these lines, whether the pump is a huge sump pump, a little metering pump or anything in the middle of, processors […]

Years of experience have been captured in a plethora of O-rings design standards and a wealth of materials is readily available to suit most application requirements. Mick Holland describes how to take advantage of these standards to mitigate risk when specifying O-rings into your fluid sealing system. Within the O-ring industry, size references are often […]
The book, published by True North Books in association with Kingfisher (Lubrication), which was founded in 1867 and which has survived the “toughs and peaks” and “vagaries of global economics” to survive into the 21st Century. It was at the beginning of that other great shift in society, when people moved from the land into […]
