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 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.

No need for expensive crimping tools—these fittings make air conditioning and refrigeration assemblies with clamps. Instead of a crimper, they use two clamps that you tighten against a cage on your fitting with pliers. Both fitting ends swivel until tightened, so you don't have to rotate the entire hose during installation. The cage and clamps stretch out after use, so they shouldn't be used again.
Fittings with an O-ring pilot create a leak-tight seal, so they’re often used in commercial and vehicle air conditioning systems. When you screw the fitting onto your tube, the bead and the pilot squeeze the O-ring, which fills in any gaps. The pilot also helps guide your hose onto the fitting, making it easy to properly align and secure the connection.

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.
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Mineral Oil, Refrigerant, Water; except adapters for 1/8" and 1" tube OD are not for use with fuel oil
- Specifications Met: See table
- For Use With: Air, Cutting Oil, Diesel Fuel, Fuel Oil, Mineral Oil, Refrigerant, Water; except nuts for 1" tube OD are not for use with fuel oil
- Specifications Met: SAE J512, SAE J513, UL Listed; except nuts for 1" tube OD meet SAE J512 and SAE J513 only
