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.

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.
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
- Specifications Met: SAE J512, SAE J513, UL Listed

Build-Your-Own High-Pressure Braided Chemical Hose
- Temperature Range: -40° to 350° F
- Hose: PTFE with 304 Stainless Steel Braid
- Female Fittings Swivel Until Tightened
Use shears or a cutoff saw and wrap the hose ends with tape to cut the hose to your desired length and then attach the fittings. You don’t need any special equipment to install. After you attach the fittings, be sure to test the hose for required pressure prior to using.
To attach fittings to hose, push the socket over the stainless steel braid, then wedge the sleeve under the braid. Next, insert the nipple into the hose and hand-tighten the socket onto the nipple. Finish by wrench-tightening the hex nipple until it is flush against the socket.
Female fittings are also known as JIC (Joint Industrial Council) fittings. They swivel until tightened for easy installation. Brass fittings with zinc-plated steel nut have fair corrosion resistance; 303 stainless steel fittings have very good corrosion resistance.
