What is a 37 degree flare?
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 degree is a double flare?
– double flares are used with 45 degree inverted flare fittings, which is what’s stock on older cars on brake, fuel, hydraulic, and vacuum lines. Part of this is based on the fittings – if single flared the nut may bottom out before the fitting seals.
What degree is a flaring tool?
37 Degree AN Flare Tubing Standard Tube Flaring Tool.
What is the difference between a flare and a double flare?
The single flare is very identical to the double flare. Although they look a lot alike, the double flare is much stronger and can hold more pressure build up inside the braking system. The double flare is a flare that is especially popular in vehicles imported from Europe.
ARE AN fittings 37 degree?
The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.
WHY ARE AN fittings 37 degrees?
This fitting design was the forerunner of the current AN and SAE 37° flare fittings. The U.S. Air Force, with help from Wright Patterson Air Force base, developed a fitting with 37° flare angle, before WWII, which became known as the “AN” fitting. This fitting had precision 3A/3B threads.
What the difference between 37 and 45 degree flare?
JIC 37 degree flare union fittings is in most hydraulic systems in high pressure application such hydraulic excavator, loader and tractor etc. SAE 45 degree flare fittings is used in low to medium pressure applications such as military and aerospace equipment. they doesn’t interchangeable into each other.
Will 45 degree flare seal on 37 degree?
– flared at 45 degrees would seal against a 37 degree fitting. Pay attention to what type reducer you’re using.
What is a double flare tool?
OTC’s No. 4503 Double Flaring Kit is designed to make double or single flares in copper, aluminum, and brass tubing as well as soft steel brake line tubing. Chrome plated alloy steel swivel reduces friction and helps ensure a smooth, even flare.
How do I use a double flare tool?
Position the flaring tool with the point entering the tubing end and centered. Turn the screw clockwise and tighten until the cone is bottomed out completely. Remove the flaring tool and inspect the tubing end. The flare should be even all around with no cracks or gaps.
When should a double flare be used on tubing?
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. The fitting moves against the folded over section causing that to wear and not the already thinned outer pipe wall.
Is 37 flare the same as JIC?
AN and JIC Fittings Interchangeability AN 37° flare and industrial 37° flare fittings function identically. In many cases, they appear to be functionally interchangeable, but they are not.
