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.
- 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.

The male pipe threads on these fittings have a sealant applied for extra protection against leaks. Also known as JIC (Joint Industrial Council) fittings, they provide a tight metal-to-metal seal on tubing that is flared to 37°. They’re often used in hydraulic applications. Made from 316 stainless steel, these fittings have excellent corrosion resistance. A complete fitting requires a nut and a sleeve (ferrule) for each tube end—tighten the nut to create a secure seal that withstands high pressure. Nuts and sleeves are sold separately.
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.
Compression Fittings for Stainless Steel Tubing
A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings or bite fittings. Use them in low- to medium-pressure applications.
316 stainless steel fittings have excellent corrosion resistance.
ISO and DIN fittings meet international dimensional standards.
