This style of fitting, like any other, has a basic function. To securely attach the tubes together in a safe, tight seal assembly. Close tolerance machining of high quality CNC machines allows a consistent production of all components. The dual connector end is able to lock onto the tube with a feature of "double bite". Each ring bites into the tube giving two separate sealing zones. This style of editing do so without transmitting torque or twisting of the tube so that the tube does not become "stressed." Therefore, the mechanical properties of the tube are maintained. An additional sealing point occurs at the bottom of the tube to the abutment. The pillar has an angle, the tube is forced in the rings which bite and cause the tube to the front.
Stainless steel fittings with the problem of jamming is solved by the use of silver. The internal parts of the nut are the only regions that are plated. Materials such as nickel alloys, high temperature alloys, duplex and super duplex are coated with an anti-bladder in the same way. However, molybdenum disulfide can be used as an alternative. These materials are selected to be compatible with the fluids they contain.
For the chemical stability of the ideal situation is that the two pipes and fittings are manufactured from the same type of material. There are strict assembly instructions to follow with this type of product. The rule states that for most sizes 1-1/4 rotations of the nut from the position of the finger tight, give all proper tight seal. It is allowed to continue to "tight" fitting, if a minor leak but it is not normally required.
When access to any system is necessary to provide such an excellent connections "break-in" point. Spouses can be made and remade several times without loss of sealing integrity, providing the installation instructions are correct followed. The strength of the assembly is such that the tube contained burst before installation shows no signs of leakage or movement.
This is subject to certain constraints on the thickness of the tube wall. If the wall is not too heavy rings not bite as well, as when the tube wall is too thin, the tube will collapse rather than allowing the rings to bite fully. Reference to the information product manufacturers must be made in all instances. The tube should generally have a hardness of up to 80 on scale "B" of Rockwell.
There are a number of manufacturers of such products throughout the world and they usually contain "LOK" the term in their product name. Major manufacturers to encourage users of this type of product not to inter-change of different products. It is considered sacrilegious to mix parts from different manufacturers. You should know that, with the possible exception of the two manufacturers, without exception, are based on the same original design. (The same inventor then to design two versions of the original design, the two exceptions mentioned above.) Interchangeability in this product is actually announced as positive by some companies. These same companies often provide overlapping part number in their documentation.
