McMaster 50715K692 37 Degree Flared Fitting for Stainless Steel Tubing Straight Connector with Swivel, for 1/2" Tube OD

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.

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.
