Are inverted flare and double flare the same?

The first is the inverted double flare, used by most domestic production cars and trucks. … It uses a 45* double flare to seal, which has tubing that is folded over into itself before flaring outward. The double flare is used for installations that require repeated tightening/untightening.

What is an SAE inverted flare?

SAE Inverted Flare (SAE J512) Widely used in automotive systems, the inverted flare connection features a machined male connector with a 420 seat, and a flared male tubing with a 450 seat. The female side has a 420 seat that provides a sealing surface. The threads connect together to make a mechanically strong bond.

What are the two types of brake line flares?

There are two basic types of flares used on OEM automotive brake systems throughout the world. 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.

What’s the difference between a double flare and a 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.

Do you need to double flare brake lines?

Double flares are necessary for brake lines due to the high pressures inflicted on them by the hydraulic system. Single flared lines are only appropriate for low-pressure lines due to their tendency to crack or leak.

Are all brake line fittings the same?

There are two basic sizes of brake lines. 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.

What is the difference between single and double flaring tool?

A double flare is one where the end of the line edge is folded back into the line making a concave surface. These are for high-pressure lines and single flares are only used in low-pressure line applications. Pro-tip; if you are flaring a line always remember to properly place the line nut on before flaring the end.

What is a double flaring tool used for?

The double flaring tool kit has been designed to make double or single flares in copper, aluminum, and brass tubing as well as soft steel brake line tubing.

Is single flare OK for brake line?

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.
