The three parts of SAE J cover material, dimensional, and performance requirements of steel O-ring face seal (ORFS) connectors for tubing and the O- ring. O-Lok® end. (ISO /SAE J)/dimensions. .. for identification only. Small deviations be found between SAE J or ISO on bore sizes. Catalog PDF Section Updated October . of SAE J and ISO It is an O-ring .. Sizes 14 and 32 are not included in SAE J ** These.
Long tubes or those liable to high stress must be clamped to avoid excessive vibrations. Misalignment may impair system functioning. Correct lubrication of the components to be tightened is indispensable for correct functioning of the system: mineral oil for carbon steel fittings, nickel-based anti-seizing compound for stainless steel fittings. All the fittings contained in this catalogue may be used for oleo-dynamic systems only. Is not allowed the mixing of different materials.
The indicated pressures are intended for steel tubes only. Use of tubes without the aforementioned characteristics may seriously impair the efficiency of the fitting. We recommend to use the following tubes only: seamless cold drawn steel tubes as per ST The flaring of the tube must be made with the flaring machine model and not with hand tools.
It is important that the flaring is concentrical and perpendicular to the tube and ferrule. The brazing must be made with suitable materials. In order to obtain a curve of the tube as close to the tightening point as possible Fitting body the structural constructing ties typical of the ORFS fittings must be considered.
This product forces the user to leave a part of the ending section of the tube perfectly parallel. This part must be used during the flaring operation to block the tube. Please refer to the C quote. We recommend to use the following tubes only: cold drawn seamless stainless steel tubes with no welding as per 1. This product force the user to leave a part of the ending section of the tube perfectly parallel.
At the customers request, our Quality Service will issue certificates of origin for the materials used to manufacture the products delivered. Our Quality Experts are always ready to provide customers with advice, to guide them around our facilities as to provide documentation of the traceability system applied.
The use of high quality steel tubes in the right wall thickness, make this specific type of fitting particularly safe creating values of highest reliability between the sleeve, the fitting body and the tube, since is the flared part the strong point of this technology.
Nominal working pressures indicated in this catalogue are intended as maximums including pressure peaks. To use this fitting at higher requirements test must be carried out in accordance with the manufacturer.
The safety factor is intended as static test with the temperatures within the given range and complying with all the references contained in ISO , as far as tube connection is concerned. The size symbol for all tube sizes shall be the tube 00 or nominal hose 10 in millimeters, except dash size symbols may be used for braze sleeve and weld nipple for inch 2. Torque values listed in Table 1 are for controlled testing to established compliance to the performance requirements set forth in Part 2.
Recommended assembly torques by manufacturers may vary from Table 5. This covers unions, caps, bulkheads and swivels. Screw threads on the port end of the connectors shall be metric per ISO The dash size symbol applicable to all tube ends and straight thread a-ring boss ends shall consist of the number of sixteenth inch increments contained in the outside diameter of 2.
Torque values listed in Table 2 are for controlled testing to establish compliance to the performance requirements set forth in Part 3. Recommended assembly torques by manufacturers may vary from those shown in Part 3. This covers unions, caps, bulkheads and swivels, and plugs. For -4 only, adjustable torque is given. SCOPE 1. SAE J covers the requirements for "metric based" O-ring face seal connectors to metric stud ends along with the associated adapters, bulkhead and union connectors.
Metric hex wrenching flats are used throughout this standard. These connectors are capable of providing leak proof full flow connections in hydraulic systems operating from 95 kPa vacuum to the working pressures shown in Table 3.
Since many factors influence the pressure at which a hydraulic system will or will not perform satisfactorily, these values should not be construed as guaranteed minimums.
For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and manufacturer to ensure that required performance levels are met.
For use of these connectors in conditions outside the pressure and temperature limits specified, the manufacturers must be consulted. Both metric and inch tubing can be accommodated by changing only the sleeve to match the tube diameters. In the past, these connectors have been used predominantly with inch tubing.
For new designs metric tubing should be considered. Unless otherwise indicated, the latest version of SAE publications shall apply.
For a complete list of all references, see SAE J See Figure 6. SAE 3. From ISO 3. This type of stud end is typically used on shaped connectors e. See SAE J for specific size details.
Dimensions specified apply to finished part. For jump size connectors, the larger end is considered standard and is the basis for dimensions and tolerances overall, end to center, stock size, etc.
Drill Passages-At manufacturer's option, drill through passages in straight special size iump fittings may conform to the smaller diameter specified for up to two step size difference, or conform to one of the following for any size difference: a. The appropriate end may be countersunk to the larger diameter, or b.
The Standard is downloaded from www. Metric tubing shall be considered, see ISO for sizes. These pressures were established using connectors made of low carbon steel and tested according to SAE J This includes unions, swivels, bulkheads, plugs, and caps.
To convert from MPa to psi multiply by , for example, 63 MPa equals psi. Metric tubing shall be considered.
See SAE J for sleeve dimensions. The size symbol for all tube sizes shall be the tube OD or nominal hose ID in millimeters, except dash size symbols may be used for inch tube and braze sleeve and weld nipple for inch tubing. Equivalent dimension in millimeters.
SAE J may require sizing to meet these limits for brazing. SAE 4. See 4. The basic forging size may be increased up to the maximum size shown for barstock, but the size selected shall be a nominal metric wrench size across flats with minus tolerance only. Minimum across corner hex dimensions are 1. The minimum side flat is 0. See Figure 7. Connectors shall pass the burst, cyclic endurance impulse , vacuum and overtorque tests when tested per SAE J Recommended assembly torques by manufacturers may vary from the torques in Table 6.
Cyclic endurance test pressure. In accordance with ASME Torque values listed in Table 6 are for controlled testing to established compliance to the performance requirements set forth in Table 3. Recommended assembly torques by manufacturers may vary from Table 6.
SAE 6. All passages must be securely covered to prevent entrance of dirt or other contaminants prior to assembly and for parts distribution, handling, and storage.
Paper caps and plugs are not permitted. The connector designation consists of a basic code symbolizing in sequence the following: a the connector type, b the connector shape, and c the connector connecting ends. A "M" is inserted after the connector type to indicate a metric hex or wrench flat.
Suffixes are to be added to indicate the style and material. See SAE J for more complete information. These are added to the connector designation and modifiers. See Table 1 for the cross-reference between inch dash size designations and ISO metric tube designations.
The manufacturer shall provide assembly instructions for the proper use of the connectors. These instructions shall include at least the following details: a. Details relating to material and quality of suitable tube. Details concerning the preparation of selected tube. Details concerning the attachment of the braze sleeve and weld nipple to the tube.
