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.

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.
Fittings with a 45° flared end are also known as refrigeration and SAE fittings.

- Maximum Pressure: 250 psi @ 72° F
- Temperature Range: -40° to 160° F
- Attachment Type: Use Crimp-On Hose Ferrules, except For 1/2" Hose ID: Use Band-and-Buckle Clamps
- Specifications Met: SAE J476
Metal Push-On Barbed Hose Fittings for Air and Water
Fittings have sharper barbs than standard barbed hose fittings to grip rubber push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip.
Brass fittings are softer than other metal fittings, so they’re easier to thread together. They have good corrosion resistance.
Fittings with a flared end meet JIC or SAE standards for dimensions. Fittings with a 45° flared end are also known as refrigeration and SAE fittings.The optional installation tool (sold separately) allows you to connect large quantities of barbed fittings to push-on hose. Use the built-in cutter to squarely cut the hose without fraying. Then, clamp the hose into the tool’s vise and apply light pressure on the handle to drive into the fitting.
Note: To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

Nuts for High-Pressure Nipples for Compressed Gas
Slide a high-pressure hose nipple for compressed gas into one of these nuts to connect a pipe to the inlet of a pressure regulator. They are also known as CGA (Compressed Gas Association) nuts and inlet nuts.
Brass nuts have good corrosion resistance and are softer than 316 stainless steel nuts, so they're easier to thread together. Aluminum-plated brass nuts have better corrosion and wear resistance than unplated brass.
Note: Nuts have a CGA, BS, or DIN number that corresponds to a specific type of gas. Choose a nut with the same number as your tank and other system components.

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.
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.

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
- Specifications Met: SAE J512, SAE J513, UL Listed, except socket-connect fittings and fittings with BSPT thread meet SAE J512 and SAE J513 only
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.

- For Use With:
NPTF Threads: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Mineral Oil, Refrigerant, Water
BSPT Threads: Air, Cutting Oil, Diesel Fuel, Mineral Oil, Refrigerant, Water
