![]() Miniature compression fittings are found in applications ranging from chromatography and bomb detection instruments, to medical devices and inkjet printing. Particularly useful for their extreme temperature and pressure capabilities, and their compatibility with aggressive fluids, compression fittings can be seen in systems varying from gas lines in refineries, to the plumbing under your sink. After that, check the penetration of the cutting ring.Compression fittings are one of the most common and versatile methods of connecting metal or hard plastic tubing. Please note that we should turn the nut instead of the fitting body. Then, hand-tighten the nut, and the wrench tighten 1 1/4 turns, by holding the fitting body with a second wrench, for final assembly. Then, insert the tube into the fitting body, up to fitting stopper with nut and cutting ring. To assemble the fitting with the tube, first, place the pre-oiled nut and cutting ring over the tube in the right direction. Please note that normal grease is not recommended for lubrication. We also need to lubricate the threads of the nut and the body of the fittings, the cutting ring and the 24˚ cone using a suitable lubricant like anti-bloc fett. ![]() After sawing off the tube, do use deburring tools to lightly deburr the inner and outer diameter of the tube ends. Saw machines are recommended for sawing off tubes. ![]() The material of fittings and tubes must be similar, except for copper tubes, which are used together with brass fittings. Compression Fittings Assembly Instruction: īefore assembling DIN fittings with tubes, we need to put attention on some details. Stainless steel fittings are readily accessible in the market.Ħ. They are resistant to corrosion and chemical damage as a minimum of 11% chromium is present in stainless steel. Stainless Steel Fittings: Stainless steel fittings encompass selenium, aluminium, silicon, nickel, molybdenum, chromium, sulfur, nitrogen, copper and selenium.Besides, they are resistant to extreme weather conditions and corrosion. Carbon steel fittings have the high strength quality which is durability due to its chemical composition. Carbon Steel Fittings: Iron, carbon, manganese, copper, silicon, sulfur, phosphorus, molybdenum, nickel, chromium, and vanadium are all contained in carbon steel.Brass is a metal made up of copper, zinc, and other metals which makes the material corrosion resistant and ideal for the production of a variety of tools, such as compression single ferrule fittings. Brass fittings can withstand high pressures and maintain their structure for a long time. ![]() The strengths of brass fittings are durability and high corrosion resistance. It has grown in popularity due to its topical relevance and dynamic traits.
