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, JIC, SAE J514, except fittings with BSPP and BSPT threads meet JIC and 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 are 316 stainless steel for excellent corrosion resistance. Fittings require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.

Precision AN 37° Flared Fittings for Stainless Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -320° to 1200° F
- Tubing: Use with seamless 304 or 316 stainless steel
- Specifications Met:
All fittings: AS (formerly AN), ASTM A380, JIC, SAE AS841; Straight reducing adapters also meet NAS1564
The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings. They are made to exact AS (formerly AN) specifications. Also known as JIC (Joint Industrial Council) fittings, they provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

Vibration-Resistant Precision AN 37°
Flared Fittings for Stainless Steel Tubing
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -320° to 500° F
- Tubing: Use with seamless 304 or 316 stainless steel
- Specifications Met: AS (formerly AN), ASTM A380, JIC
A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications. The threads on the tube end are Class 3A and adhere to tighter tolerances than other 37° flared fittings. They are made to exact AS (formerly AN) specifications. Also known as JIC (Joint Industrial Council) fittings, they provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are 316 stainless steel for excellent corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.
