What is a female flare 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 size is 3/8 flare?
JIC 37° Flare (SAE J514)
| Inch size | Dash size | Male Thread O.D. (in) |
|---|---|---|
| 1⁄4 | -4 | 0.44 |
| 5⁄16 | -5 | 0.50 |
| 3⁄8 | -6 | 0.56 |
| 1⁄2 | -8 | 0.75 |
How do you measure brass flare fittings?
1) With a caliper, measure the thread diameter at the widest point across the threads (See image below). Outside diameter (O.D.) of male threads. Inside diameter (I.D.) of female threads.
How do you measure a womens flare fitting?
Female connections are measured by inserting the ID portion of the gauge into the connection on the sealing surface. Be sure the centerlines of the connection and gauge are parallel to identify the correct angle. For male flare type connections, place the gauge on the sealing surface to establish the measurement.
Do you tape flare fittings?
The threads in a flare fitting are NOT tapered and do not need to be sealed. The seal is between the flared end of the pipe/tube and the tapered face of the other side of the fitting. All the threaded collar does is supply force to create a seal between the opposite tapers of the two ends.
How are flare fittings sized?
Female connections are usually measured by inserting the gauge into the connection and placing it on the sealing surface. If the centrelines of the connection and gauge are parallel, the correct angle has been determined. Male flare type connectors are usually measured by placing the gauge on the sealing surface.
What is the thread size for a 3/8 compression fitting?

How is flare size measured?
How are women’s thread sizes measured?
Measure the thread diameter with your caliper. For male threads, measure the Outside Diameter (O.D). For female threads, measure the Inside Diameter (I.D).
Can you over tighten a flare fitting?
Fourth, don’t over-tighten the flare fitting, as this can cause leaks.
Do they make female compression fittings?
Compression Female Nut Because of their durability, pressure and chemical resistance, compression adapters are used to convert between a threaded port and a compression connection to rigid tubing. The compression adapter is available with either male or female NPT (National Pipe Taper) threads.
