What is an inverted male flare?

Inverted Flare Hydraulic Tube Fittings Recommended or use in hydraulic brake, power steering, fuel lines and transmission cooler lines. Inverted flare fittings are inexpensive and reusable. Inverted flare provides excellent vibration resistance. Seats and threads are internal and protected.

How does an inverted flare fitting work?

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. On the right, is a 37* single flared line with a tube sleeve and coupler that allows you to adapt to AN fittings.

Is an inverted flare the same as a 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.

What is a male flare fitting?

Flare fittings are a type of compression fitting used with metal tubing, usually soft steel, ductile (soft) copper and aluminum, though other materials are also used.

What is 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.

Can I use a double flare instead of a bubble flare?

The bubble flare brake lines are the first step in producing the double flare brake lines. This suggests that you will have to go through creating a bubble flare before using the double flare in the braking system of your car. On the other hand, it is also possible to create a bubble flare from a double flare.

What angle is an inverted flare?

In the first image above, the SAE double inverted flares are considered to have a 45 degree angle – this angle matches the female end of the fitting, whereas the male end has a 42 degree angle. During assembly, as the tube nut is tightened, the male end deforms to match the angle of the female end.

What is a flare nut wrench used for?

Flare nut wrenches are a type of open-ended wrench that’s intended for use with hexagonal nuts and fittings, which are sometimes referred to as flare fittings. Visually, they resemble box or ratchet wrenches but with an open head instead of a closed loop.

What is better flare or compression fittings?

Generally speaking, compression outlets are used for water and compressed air lines, where slight leakage isn’t going to cause too much of a problem. Flared outlets are used for gas and high-pressure lines, where even a little leakage can cause major problems if left unattended.

Is a bubble flare a single flare?

It looks similar to a single flare but it is much stronger and acceptable for the high pressure found in a brake system. Double flares are found on most all US manufactured cars through the 80’s. 3. DIN/ISO or “Bubble Flares” are common on many import vehicles especially European vehicles.

What do you call an inverted 45 degree flared fitting?

Fittings are also known as inverted 45° flared fittings, refrigeration fittings, and SAE fittings. To assemble, place the nut (sold separately) on the tubing, flare the end of the tubing, then insert the tubing into the fitting and tighten the nut. Fittings are brass for good corrosion resistance.

How do you make an inverted flare fitting?

•Assembly Instructions – 1)Cut tubing to desired length. Make sure all burrs are removed and the ends are cut square. 2) Slide nut on tube. Threaded end “A” of nut must face out. 3) Flare end of tube with a 450 flaring tool, a) Measure flare diameter. b) Examine flare for excessive thin out.
