The HEWCHO hydraulic fitting according to the norms ISO 8434-2/ SAE J514, is a mechanical fitting traditionally used for high pressure oleo-dynamic systems. The sealing is made by the contact between two metal surfaces, with no deformation of the single compo-nents. The coupling between the body of the fitting and the flared tube (cone angle 74°„) is guaranteed by the tigh-tening nut and by the pressure sleeve on the inside. This allow to realize a fast assembling-disassembling tube making the easiest realization of complex oleo-dynamic systems.
37° flare fittings perform well in severe applications where vibration, high pressure, and thermal shock exist. The flare fitting sleeve insures tube alignment with the fitting body axis and minimizes mechanical strain on the tube.
Flare fitting design allows for repeated disassembly and re-assembly with no need to replace any components. A wide range of configurations are available such as straight connectors, elbows, union, tees, and crosses as well as unique special adapters. Standard flare fitting materials include brass, carbon steel, and stainless steel.
Assembly performs extremely well even under severe vibration and thermal shocks Upon tightening, the sleeve ensures tube alignment with fitting axis, reduces mechanical strain on tube and compensates for vibration Fitting can be equally coupled to metric or fractional tubes Tube does not undergo distortion, remains constant and fluid pressure losses are negligible The system leak free integrity remains after disassembly and reassembly Individual replacement of any component
