What are two standards for flare fittings?
What are two standards for flare fittings?
The most common flare fitting standards in use today are the 45° SAE flare, the 37° JIC flare, and the 37° AN flare. SAE 45° flare connections are commonly used in automotive applications as well as for refrigeration and air conditioning. SAE fittings are typically made from brass.
What is a flare nut fitting?
A flare fitting has a tapered end that fits into a flared piece of tubing and is secured in place with a sleeve and flare fitting (threaded nut) to produce a pressure-resistant, leak-tight seal.
What are the dimensions of a 3/8 flare fitting?
SAE 45° Flare (SAE J512)
| Inch size | Dash size | Female thread O.D (in) |
|---|---|---|
| 1⁄4 | -4 | 13⁄32 |
| 5⁄16 | -5 | 15⁄32 |
| 3⁄8 | -6 | 9⁄16 |
| 1⁄2 | -8 | 11⁄16 |
What size is my flare fitting?
Flare Fitting
| Nominal Size | Female Thread I.D. (In.) | Male Thread O.D. (In.) |
|---|---|---|
| 3/8 | 9/16 | 5/8 |
| 7/16 | 5/8 | 11/16 |
| 1/2 | 11/16 | 3/4 |
| 5/8 | 13/16 | 7/8 |
Is flare the same as NPT?
NPT or IPT pipe threads are tapered, Compression Fitting Threads are Parallel. On the other hand compression fittings and flare fittings use threads that are cut in parallel, without taper.
How do you measure a man’s flare fitting?
Male flare type connectors are usually measured by placing the gauge on the sealing surface. If the centrelines of the connection and gauge are parallel, the correct angle has been determined.
What is 37 degree flare used for?
37° flare fittings perform well in severe applications where vibration, high pressure, and thermal shock exist. The flare fitting sleeve insures tube alignment with the fitting body axis and minimizes mechanical strain on the tube.
What is the difference between NPT and flare?
What thread size is a 6AN fitting?
The Good News
| Male Thread Size | AN Size* | Equivalent Tube Size (Nominal OD) |
|---|---|---|
| 9/16-18 | 6AN | 3/8″ |
| 3/4-16 | 8AN | 1/2″ |
| 7/8-14 | 10AN | 5/8″ |
| 1 1/16-12 | 12AN | 3/4″ |
ARE AN fittings the same as flare fittings?
Each AN size also uses its own standard thread size. AN fittings are a flare fitting, using 37° flared tubing to form a metal-to-metal seal. They are similar to other 37° flared fittings, such as JIC, which is their industrial variant.
