What is an ISO flare?
ISO bubble flares are essentially the same components as plain bubble flares; the difference between the two types lies in the fact that ISO bubble flares have pipes and threads measured in metric sizes rather than in inches.
What is the difference between double flare and bubble flare?
Just like the double flare, the bubble flare may also be called something else such as DIN or ISO. When creating a bubble flare, you have one less step. When someone is making a double flare, they actually start out by making a bubble flare before that.
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 type of flare is used mostly in the United States?
The SAE/double (inverted/45degree) flare and the DIN/ISO bubble flare. We will refer to them as SAE or DIN flare. The most common is the SAE flare. Typically found on all American and Asian cars, but the European style DIN flare is appearing everywhere now.
What is the most common brake line size?
The two most common brake lines found are 3/16″/4.75mm and 1/4″. The smaller size is 3/16″/4.75mm brake line, CNF-3; and the larger size is 1/4″, CNF-4. 3/16″ is found on virtually all cars and trucks made in the world.
Is inverted flare the same as double flare?
It’s called inverted because the adapters are female and the nuts on the lines are male. DOUBLE flare has nothing to do with the types of fittings or inverted or SAE. Double flare means you make a “double fold” with the tool. This folds the raw edge of the line in like a cuff on your pants to prevent it from splitting.
Can you single flare brake lines?
1. Single Flares are only acceptable on low-pressure lines, but not acceptable for high-pressure brake systems. A single flare is just as it sounds, the line is flared out just once in a conical shape. Single flares are not acceptable for brake lines and tend to crack and leak quite easily.
What are 45 degree flare fittings called?
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. SAE and AN/JIC connections are incompatible due to the different flare angle.
