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.

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. Next, lubricate either the push-on hose, fitting or both. 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.

Screw-On Hose Fittings for D.O.T. Hose

Create or repair D.O.T. hose assemblies in the field with just a wrench and a vise, no crimper required. To install, separate the two pieces of these fittings. Screw the hose-end portion onto your hose, then thread the nipple portion into the hose-end portion. When assembled, these fittings compress against the hose to form a strong seal. Also known as reusable fittings, they can be unscrewed from your hose and used on a new one. All meet labeling and performance requirements for motor vehicle brake hose fittings.

Fittings with a flared tube connection swivel 360° until tightened for easy installation.

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.

Nuts for Barbed Hose Fittings for Compressed Gas

Also known as CGA (Compressed Gas Association) nuts, these are designed for low-pressure welding applications downstream of your tank and pressure regulator. Slide a barbed hose adapter for compressed gas into a male or female nut to make a threaded connection to torches or pressure regulators.

Nuts with left-hand threads are identified with a notch.

Brass nuts have good corrosion resistance. Note: Nuts have a CGA number that corresponds to a specific type of gas. Choose a nut with the same CGA number as your tank and other system components.

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.

Specifications Met: SAE J512

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal. Fittings have a single sleeve (ferrule) that compresses the tubing as you tighten the nut. The nut and sleeve are included. Fittings are also known as flareless fittings. They are brass for good corrosion resistance.

Tubing: See table
Specifications Met: NSF/ANSI 61

Made of moisture-resistant acetal, these fittings won't absorb water and lose strength, even in high-humidity environments. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. All meet NSF/ANSI 61 for use in drinking water systems.

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.

UN/UNF (SAE Straight) threads are also known as O-ring boss threads.

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

Supported 45° Flared Fittings for Copper and Brass Tubing

For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Mineral Oil, Refrigerant, Water
Temperature Range: -65° to 250° F
Tubing: Use with seamless brass and copper
Specifications Met:
Metric: SAE J512, SAE J513, UL Listed
All other fittings: SAE J512, UL Listed; except tee connectors for 1/2" tube OD

The flared end nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 45° flared fittings, refrigeration fittings, and SAE fittings. To assemble, place the nut (sold separately) on the tubing, flare the end of the tubing, then insert the tubing into the fitting and tighten the nut. Fittings are brass for good corrosion resistance.

NPTF (Dryseal) threads are compatible with NPT threads.
