There is a vast and diverse range of air fittings. Given below is some relevant information about them.
Pneumatic Fittings- These connect sections of pipe, hose and tube networks. These are put to use in pneumatic logic control systems as well as instrumentation. Their role is far more critical than merely connecting a pipe or a hose to air powered devices. On the contrary, these fittings facilitate the crucial control and safety operations in the process making valves and other devices unnecessary for the circuit in question.
Pneumatics system designers try to combine diverse capabilities into one unit offering not only a compact and streamlined size but also lowered chances of any leaks, easier installation and possibly lower costs. These air fittings are truly versatile in that they come in myriad sizes and configurations and are composed of different materials like brass, plastic, stainless steel and steel.
Seals that withstand high temperatures- If one’s hydraulic equipment is regularly subject to high increases in temperature, the regular industry standard thermoplastic polyurethanes may not do the job, in so far as sealing goes. That is where specialised high-temperature polyurethane seals manufactured by companies like Resilon provide extra protection.
In particular, Resilon 4350 can withstand a temperature that is as high as 250 to 300 degrees F . Not just that, it enhances sealing force by 30% This is possible on account of it using high-temperature nanotechnology that does not permit polymer degradation. The resultant extended seal life results in savings made by way of not having to replace failed seal systems.
How to select air fittings- There a number of factors that decide the choice of a particular air fitting. These include-working pressure & environment, type of load(air, water, oil, etc.),working temperature, material used to make the fittings(plastic, stainless steel , brass), shape( whether straight, elbow and so on), size( that of pipe and thread) and the kind of approvals mandatedThe plastic push -in fitting type for example, is best suited for use in polyurethane and nylon tubing.
Brass push in fitting, on the other hand, are mainly made with nickel coated brass, though composite ones made with glass-reinforced nylon are also available. What is good about brass push- in fittings is the fact that these can be easily disconnected as well reconnected making them ideal for use in a dynamic and ever-changing environment. These are quite versatile in that they can be used with nylon, polytherane, PE and other types of tubes.
Stainless steel push- in fittings on their part permit fast circuit assembly for passage of compressed air, and other gas across a wide range of pressure and temperature. Connections can be made and unmade manually in no time. Incorporation of the stainless steel colet design ensures superiors clamping with different types of tubes including nylon, polyethylene and polyurethane.These fittings are ideal for use in robotics and conveyor systems or for that matter on any system that requires the transfer of compressed air.
As we can see above, air fittings fulfil a variety of crucial functions across industry. It is vital that one have thorough knowledge of the kind of air fitting that best suits one’s process or industry, before placing an order. The good news is that there is a large number of manufacturers of pedigree who produce a wide range of air fittings used in a number of industries.
