Hydraulic and Pneumatic Seals are mechanical devices placed in compression between two objects, so as to prevent the escape of fluids or gases.
At first sight a mechanical seal seems a simple and easy-to-use device but it is better to know all its possible fields of application because a wrong choice in design, size or material could compromise the entire device where they are applied.
Did you know that in January 1986 the cause of the Challenger space shuttle disaster was attributed to the malfunctioning of an O-ring? Determining factors in the space disaster were both the low temperature prior to launch, which made the ring too harsh, and the wrong choice of the material: Viton. This material in fact is not particularly recommended for applications at low temperatures since it takes twice the time, compared to other materials, to return to its original shape after freezing. It took only a small loss of fuel to detonate the shuttle 73 seconds after the launch!
When you choose a seal it is therefore essential to take into account several factors such astemperature, pressure, composition of the fluid process and of the mechanical load that must be supported. Choosing the right design and the suitable material help - as well as to avoid cosmic disasters - to increase the long-life service of the seal and to reduce both maintenance times and costs of the system.
Net Seals, thanks to its very experienced team of professionals, which every day works to meet your enquires, offers a wide range of components for all applications fields of hydraulic devices and for all standard sizes. We can provide both sealing systems for housings comply with international standards and specific solutions for each customer, while maintaining high standards in order to meet the most demanding applications.
Our product range includes:
The many different fields of application of seals allow Net Seals to enter every day in contact with different companies belonging to different sectors: agriculture, construction, automotive, shipbuilding, steel industry and metallurgy etc..
By the early 1940’s - when the first dynamic O-ring in history was perfected and patented by an American inventor, Niels Christensen, seals consumption started growing more and more.
During the Second World War, the O-ring became the standard seal for all hydraulic systems of the Us Air Force, and In the 1950's, came acceptance for industrial hydraulics, farm equipment, and so on.
Today billions of hydraulic and pneumatic seals are sealing every conceivable apparatus all over the world. We can find it in the air, on land, in the sea, and even in space.
It is therefore essential in choosing a sealing element being supported by a technical specialist who can suggest and guide customers through the most suitable solutions.
