How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

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.

BSPP threads and UN/UNF (SAE Straight) male threads have a gasket to protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

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.

45° Flared Fittings for Copper and Brass Tubing

Temperature Range: -65° to 250° F
Tubing: Use with seamless brass and copper that meets ASTM B280

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They require a nut (sold separately) for each tube end. Fittings are also known as refrigeration and SAE fittings. They are brass for good corrosion resistance.

NPTF (Dryseal) threads are compatible with NPT threads.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Metal Barbed Hose Fittings for Air and Water

Slide the barbed end into rubber hose and secure with the appropriate clamp or crimp-on hose ferrule.

Brass fittings are softer than other metal fittings, so they’re easier to thread together. Plain brass fittings have good corrosion resistance. Fittings with a threaded end are also known as hose nipples.

Metric, UN/UNF (SAE Straight), and BSPP male threads with gasket protect against leaks. UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

Threaded Hose Fittings for Compressed Gas

Use these fittings to connect welding hose to pressure regulators and torches. They are also known as CGA (Compressed Gas Association) fittings. Fittings are brass for good corrosion resistance.

Fittings with left-hand threads are identified with a notch in the nut.

Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.

Couplers for High-Pressure Fill Valves

Fill tanks and recharge struts—these couplers join hose to high-pressure fill valves with Schrader threads.

Some couplers meet SAE AS4395, an automotive industry standard for flared fitting dimensions.

Couplers with a shut-off valve let you control the flow of air by hand. When used with Schrader valves that have a core, the core depressor pin in these couplers press valves open to let air flow in.
