Specification summary of SAE J514 as applied to jic 37-degree flare fittings: the dimensions the standard fixes, the full size range supplied, and the related designations commonly cross-referenced.
SAE J514 — Scope
The table below lists the dimensions catalogued for jic 37-degree flare fittings under SAE J514. The scope of SAE J514 itself is not summarised here — where a figure matters, confirm it against the published document.
Tolerance & Product Grades
Product grade is a concept from dimensional fastener standards and does not apply to SAE J514. Tolerances for this part are the limits shown against each dimension in the table.
Dimensions Specified by SAE J514
| Dash size | Tube outside diameter | Thread (UNF) | Cone angle |
|---|---|---|---|
| -04 | 1/4 in | 7/16-20 | 37 degrees |
| -05 | 5/16 in | 1/2-20 | 37 degrees |
| -06 | 3/8 in | 9/16-18 | 37 degrees |
| -08 | 1/2 in | 3/4-16 | 37 degrees |
| -10 | 5/8 in | 7/8-14 | 37 degrees |
| -12 | 3/4 in | 1-1/16-12 | 37 degrees |
| -16 | 1 in | 1-5/16-12 | 37 degrees |
| -20 | 1-1/4 in | 1-5/8-12 | 37 degrees |
Equivalent Standards
Where direct equivalents exist (ISO ↔ DIN, ISO ↔ ASME), they are listed on the parent JIC 37-Degree Flare Fittings page.
Always confirm against the dimensions on this page, since some "equivalent" standards differ in tolerances and head geometry.
Companion Standards
A complete specification for jic 37-degree flare fittings normally cites several documents: one for the geometry, one for the material or mechanical properties, and one for the finish. SAE J514 is one of them, not all of them.
Custom manufacturing · Made to drawing
Need a pipe & pneumatic fitting to this standard in a non-standard size?
Parts built to SAE J514 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
