About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

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 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.

Straight Adapters (Swivels Until Tightened), Female Tube × Male Threaded Pipe

For Use With: See table
Temperature Range: See table

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.

37° Flared Fittings for Steel Tubing

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.

NPTF (Dryseal) threads are compatible with NPT threads.

Straight Adapters (Swivels Until Tightened), Female Tube × Female Threaded Pipe

Temperature Range: -60° to 400° F

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.
