37° Flared Fittings for Stainless Steel Tubing
- Tubing: Use with welded or seamless 304 or 316 stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
- Specifications Met: ISO 8434, SAE J514, except fittings with BSPP and BSPT threads meet SAE J514 only
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They withstand high pressure, so they’re often used in hydraulic applications. Made from 316 stainless steel, they resist corrosion from water and chemicals. A complete fitting requires a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.

- For Use With: See table
- Temperature Range: See table
Fittings that swivel until tightened have a built-in nut that rotates 360° for easy installation.
Fittings with female tube end have an internal flare that mates with the male tube end of another fitting.

37° Flared Fittings for Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil
- Tubing: Use with seamless steel
- Specifications Met: SAE J514
Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on tubing that is flared to 37°. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately. Fittings are zinc-plated steel for fair corrosion resistance.
NPTF (Dryseal) threads are compatible with NPT threads.
