Iso 12151-5 Pdf

ISO 12151-5 specifies the general and dimensional requirements for the design and performance of 37flared hose fittings in accordance with ISO 8434-2, made of carbon steel, for nominal hose inside diameters of 6.3 mm to 51 mm inclusive, in accordance with ISO 4397.
Winner call this type hose fitting as JIC(Joint Industrial Council ) hose fitting, and part no. is 167xx for male hose fitting and 267xx for female hose fitting. Below is some typical picture for these series.
ISO 12151-5 hose fitting (37flared hose fitting / JIC hose fitting) are for use in hydraulic fluid power systems with hose that meets the requirements of the respective hose standards and in general applications with suitable hose.
When install the 37flared JIC hose fittings to other connectors or tubes shall be carried out without external loads, and tighten the hose fittings as the number of wrenching turns or assembly torque, and when tighten the hose fittings need keep the hose no twist, otherwise the life of hose will be reduced.

Also referred to as Whitworth threads, the BSP thread type fittings seal using metal to metal angled surfaces or a combination of metal to metal and an O-ring. The angle of the sealing surfaces is 60 for both forms.
There are two popular thread forms, British Standard Pipe Parallel (BSPP) and British Standard Pipe Tapered (BSPT).
Identification is made by measuring the outside diameter of the thread and the number of threads per inch (25.4 mm)
Commonly referred to as just JIC fittings these metal to metal sealing type fittings have a 37 flare (sealing surface angle) and straight United National Fine straight Threads (UNF).
The original design specification for the fittings comes from the Society of Automotive Engineers (SAE) and these fittings are the most common American fitting type in Europe.

ORFS fittings are becoming the most popular international fitting type used on global OEM machines due to their high level of sealing and their good vibration resistance. The fittings use the O-ring compression mechanism to seal.
The female fittings have flat faces and straight threaded UNF swivel nuts. The male fittings have the O-ring in a groove in the flat face.
Seen as a major advantage, these fittings offer the possibility to build the hose assemblies into fixed distances/spaces, without having to move back other system components due the flat faces of the male and female fittings - the hose assembly can be slotted in.

The 4-bolt split flange (or full flange) fitting is used worldwide for connecting high pressure hoses typically to pumps, motors and cylinders, where the hose assemblies are subjected to large pressure loadings.
The sealing mechanism is through compression of the O-ring in the face of the flange head against the surface of the port/ connection.
The flange fittings are generally separated into two pressure classes referred to as 3000 psi (SFL) or 6000 psi (SFS).
ISO 12151-3 refers to the flange fittings as code 61 for the 3000 psi and code 62 for the 6000 psi.
In addition to these flanges, customer specific Komatsu and CATERPILLAR flanges can also be found in the market.
