Tube fitting comprise a total of three main parts, Namely fitting body, Coupling nut and a ferrule that serves as also termed as cutting ring, Progressive ring etc tube fittings perfectly suited for metric size tubes. Imperial size tube fittings are also manufactured by. Original metric fitting design is based on german standard. I. E. Din 2353. Later international standards organization formed a technical committee and released a standard as iso 8434 as a basic standard. Tube fittings as a broad term used by different industries with different fitting arrangement grounded in the application. Many types are tube fitting designs can be found presented as of mentioned below, Ferrule type / flare less weld on nipples 37?? flared fittings o, Ring face seal fittings iso has released different standards for all above types of tube fittings. The layout of tube fitting body, Coupling nut and ferrules are derived from ISO standards standards. The dimensions and the requirements are well defined by these standards. A selection of the key parameters for the attachment design are left to the manufacturer to have their choice of design specifications. Tube fitting body has 24 ?? cone with excellent surface finish for to get lower friction during assembly coupled with a provision to receive a tube with metric threads. Coupling nut has also metric internal threads with a support flange inside to propel the ferrule during assembly process. Ferrule design is very special in its geometry and metallurgy. The design has twin cutting edges which firmly grips the tube after assembly thereby creates a spill-resistant design joint. Has such tube fittings in many sizes and different configurations.
