45° Flared Fittings for Copper and Brass Tubing
- Temperature Range: -65° to 250° F
- Tubing: Use with seamless brass and copper that meets ASTM B280
No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They require a nut (sold separately) for each tube end. Fittings are also known as refrigeration and SAE fittings. They are brass for good corrosion resistance.
Metric and UN/UNF (Straight) threads have a gasket to protect against leaks. Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

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.
