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 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.

- For Use With: Air, Hydraulic Fluid, Isopropyl Alcohol, Natural Gas, Phosphoric Acid, Water
- Temperature Range: -420° to 1,200° F
Through-wall fittings are also known as bulkhead couplings and panel-mount couplings; they mount through your wall or panel to create an inlet or outlet.

Made to tighter tolerances than other compression fittings, these are designed for high-precision applications. Also known as instrumentation fittings and flareless fittings. They come with a nut and a single sleeve (ferrule). The sleeve bites into tubing as you tighten the nut to create a strong seal. Fittings are 316 stainless steel for excellent corrosion resistance. A molybdenum disulfide coating on the nut acts as a lubricant for easy installation.
