Sleeves for 37° Flared Fittings for Stainless Steel Tubing
- For Use With: Air, Hydraulic Fluid, Isopropyl Alcohol, Natural Gas, Phosphoric Acid, Water
- Temperature Range: -420° to 1,200° F
- Tubing: Use with seamless or welded 304 or 316 stainless steel that meets ASTM A213, ASTM A249, or ASTM A269
- Specifications Met: ISO 8434, SAE J514
Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on stainless steel tubing that is flared to 37°. Sleeves are 316 stainless steel for excellent corrosion resistance. They are also known as ferrules.
Inch × metric sleeve adapters convert the fitting from inch to metric.

37° Flared Fittings for Steel Tubing
Male Threads with
Gasket and Washer
- 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.
To prevent leaks, UN/UNF (SAE Straight) male threads have a gasket. Metric and BSPP male threads have either a gasket or a gasket and washer.

Tight-Space 37° Flared Fittings for Steel Tubing
- Temperature Range: -20° to 212° F
- Tubing: Use with seamless steel
- Specifications Met: SAE J514
The external hex bolt on these fittings allows for easy installation in cramped spaces. Fittings are also known as banjo-style fittings and JIC (Joint Industrial Council) fittings. They provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are zinc-plated steel, which has fair corrosion resistance.
