Metallic Connections for Fluid Power and General Use Part 1: 37 Degree Flared Fittings
RATIONALE
Rewrite of SAE J514 to harmonize with ISO 8434-2 where applicable, and properly organize similar adapters into individual
parts. 37 degree connectors with ISO 6149-3 stud ends are specified in ISO 8434-2 and are not included in this revision of
SAE J514.
In an effort to standardize within a global market and ensure that companies can remain competitive in an international
market, it is the intent to convert to metric hex sizes, which will:
•
Lead to one global system.
•
Guide users to preferred system.
•
Reduce complexity.
•
Eliminate duplications.
Performance requriements have been revised to remove ambiguity.
Internal and external hex O-ring plugs were removed from SAE J514. These plugs are now specified in SAE J1926-4.
Straight thread O-Ring ports, formerly part of SAE J514, are specified in SAE J1926-1.
The seat diameter d28 in Figure 15 was brought in line with diameter d24 for like parts.
Minimum stock sizes for female pipe listed in Table A9 have been revised due to a contradiction between the listed
minimums and the stock sizes specified for adapter unions, which will now appear in SAE J514/3.
37 degree fittings with NPTF pipe threads, formerly part of SAE J514, are now attached as Appendix B.
All dimensions are given in SI units. Except for nominal sizes, and thread designations, U.S. customary units have been
eliminated from this standard.

FOREWORD
The January 2012 edition of SAE J514 was a single document specifying the requirements for the following:
•
37 degree flare adapters with SAE J1926-3 stud ends and NPTF pipe ends.
•
Flareless bite type adapters with SAE J1926-3 stud ends and NPTF pipe ends.
•
O-ring plugs with internal and external hex.
•
NPTF pipe adapters
•
30 degree NPSM adapter unions.
ISO 8434-2 was published covering the requirements for 37 degree flare adapters with ISO 6149-3, ISO 1179-3,
ISO 11926-3, and ISO 9974-3 stud ends. This revision of SAE J514 adopts the connectors covered within ISO 8434-2,
incorporating the rationalized dimensions from ISO 8434-2 where applicable, for the inch (ISO 11926-3/SAE J1926-3) stud
end 37 degree connectors, as well as fitting configurations that are not specified in the ISO standard. Formerly, SAE J514
was organized as a single document with ten clauses, which included six sections. This revision of SAE J514 has been
organized into three sections as follows:
Part 1: 37 Degree Flared Fittings
Part 2: Flareless (Bite Type) Fittings
Part 3: NPTF Pipe Fittings and Pipe Unions
Grandfather clause: Fittings must conform to this revision of SAE J514 by April 1, 2025.
It is important to note that this and all SAE J-documents are intended for ground vehicle use only and not intended for
aerospace applications.
Modification of -2 through -16 sizes in these types of fittings for use with MS 33649 are no longer specified in this standard.

1. SCOPE
This part of SAE J514 covers general and dimensional specifications for 37 degree flared tube fittings. Also included are
37 degree flared fittings with NPTF pipe threads in Appendix B. These fittings are intended for general application in
hydraulic systems on industrial equipment and commercial products.
These fittings are capable of providing leak-proof, full flow connections in hydraulic systems operating at working pressures
as specified in Table 6. Since many factors influence the pressure at which a hydraulic system will or will not perform
satisfactorily, the values shown in Table 6 should not be construed as a guaranteed minimum.
For any application, it is recommended that sufficient testing be conducted and reviewed by both the user and fitting
manufacturer to assure that performance levels will be safe and satisfactory.

7. NOTES
7.1
Assembly Information
Torque values listed in Table 5 are for controlled testing to establish compliance to the performance requirements set forth
in Table 6. Recommended assembly torques by manufacturers may vary from Table 5.
Smaller sizes (-2 through -8) of 37 degree flare fittings are less tolerant to overtorque than the larger sizes. Overtorque in
these sizes causes deformation of 37 degree cone of the male end. Excessive deformation of the cone results in loss of
clamping force and, hence, loss of seal. It can also reduce flow area.
For installation information, refer to SAE J2593.
7.2
Identification Statement and Procurement Information
Use the following statement in test reports, catalogues, and sales literature when electing to comply with this part of
SAE J514/1: “37 degree connectors conform to SAE J514/1: 37 degree flared fittings.”
The 37 degree flared tube fittings shall be as shown in Figures 8 to 39 and Tables 9 to 21, as well as Appendix B. Dimensions
for double and single 37 degree flares on tubing to be used with these fittings are given in SAE J533.

APPENDIX A - TABLES FOR CALCULATING DIMENSIONS ON SPECIAL SIZES
Tables A1 through A11 and Figures A1 thorugh A3 are instructions which may be used for determining the overall lengths,
leg lengths, and stock sizes applicable to special size combination fittings not covered in the standard dimensional
tabulations.
A.1
TABLES FOR CALCULATING DIMENSIONS ON SPECIAL SIZES
Tables A1 to A7 present various factors to be used in determining the dimensions applicable to special size combination
fittings not contained in SAE J514.
In Tables A2, A5, A6, and A7, no factors are given for extreme combination sizes because of differences in factors due to
method of manufacture. These extreme conditions are rare and it is suggested a manufacturer be contacted for the proper
dimension.
No factors are given for bulkhead or swivel ends as combinations are not generally specified for these fittings.
Tables A8 to A10 present the minimum stock size acceptable for the various machine ends.
For any nonstandard size fitting, be it a connector, 45 degree or 90 degree elbow, tee, or cross, one end is always standard,
conforming to the SAE J514 tables of dimensions. Considering this end to be the largest on the fitting, it may then be used
as a basis for establishing the stock size and length (either over-all or end to center) for all other parts by deducting factors
equivalent to the reduction in machining requirements from the appropriate standard lengths as shown in Figures A2 and A3.
The factors applicable to the various end configurations and size reductions tabulated in the tables were determined on the
following basis:
Those pertaining to lengths were derived by maintaining the standard hexagon thickness for straight fittings and the standard
centerline to machining start for shaped fittings.
The factors shown in Tables A1 through A7 were derived by subtracting the standard machining length required for the
smaller end from that required for the larger standard end and rounding the result to a two-place decimal.
The minimum allowable stock size for the various types of ends are also tabulated for reference purposes.
A.1.1
Drill Passages
At manufacturer’s option, drill passages in special size (jump) 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 appropriate end may be drilled to the larger diameter up to the middle of the hex.

EXAMPLES
For a 37 degree flared male connector (Figure B1) with -8 tube OD and -12 NPTF, the overall length would be
determined as follows:
52.3 = L overall length for -12 tube to -12 NPTF from Table B3
- 5.3 = Factor from Table A1 for -8 machining on -12 size fitting
47.0 = Overall length for the nonstandard male connector
Since the -12 NPTF is the larger machining, the hex size of 28.58 (1-1/8) from Table B3 would apply.

For a 37 degree flared 90 degree male elbow (Figure B3) with -8 OD tube and -12 NPTF, the end to center length
M would be derived as follows:
42.2 = M dimension for standard -12 37 degree end
- 6.1 = Factor from Table A2 for -8 machining on -12 size fitting
36.1 = End to center length
Since the 3/4 NPTF is the standard end, the N end-to-center dimension would remain 1.59 as shown in Table B3. The
wrench flat size would be as shown by the Y column in Table B3 for the -12 tube OD.

Fittings involving hex sizes larger than “S1” shall include a turned shoulder of diameter “d26” and thickness “L45” as shown in
Figure A1. This turned shoulder permits the reduced straight thread end to seat in a standard port spot face.
For some combinations, additional length will be required to accommodate this feature. Therefore, all factors designated as plus
in above table should be added to standard length dimensions to obtain applicable values

APPENDIX B - 37 DEGREE FLARED PIPE FITTINGS
The fitting configurations represented in Appendix B are not preffered for new design.
Figures B1 thorugh B11 and Tables B1 through B4 provide specific information necessary to produce 37 degree flared
fittings with NPTF threads in accordance with this specification. All applicable provisions of SAE J514/1 apply to the
configurations specified in this appendix. Specific information required to produce these configurations follows.
B.1
ANGULAR TOLERANCE ON AXIS OF ENDS ON ELBOWS, TEES, AND CROSSES
Angular tolerance on axis of ends on elbows, tees, and crosses shall be ±2.50 degrees for 1/4 inch pipe fittings and ±1.50
degrees for 3/8 to 2 inch pipe fittings.
B.2
PIPE THREADS
Pipe threads, unless there is specific authorization to the contrary, shall conform to the Dryseal American Standard Taper
Pipe Thread (NPTF). Specifications are given in detail in SAE J476 (ANSI B1.20.3).
The length of full form external thread shall not be shorter than L2 plus one pitch (thread).
Where external pipe threads are produced by roll threading, the diameter of the unthreaded shank adjacent to shoulder
may be reduced to the E2 pitch diameter for brass fittings and to the root diameter on steel fittings.
External pipe threads shall be chamfered from the diameters tabulated below to produce the specified length of chamfer or
partial thread. Internal pipe threads shall be countersunk 90 degrees, included angle, to the diameters tabulated in Table 2.
B.3
LUBRICANT
Use of a compatible lubricant is desirable in assembling dryseal pipe threads on hydraulic tube or pipe fittings to minimize
galling and effect a pressure-tight seal.
