Lubricate the threads on the preset human body, tube nut, and outer edge of each ends of your flareless sleeve.
SAE flareless tube fittings are ideally made for many techniques mainly because it is the best fitting process for them and users don’t must flare the tube. Forstrong hydraulic units, these tube fittings are advised about An additional flare less tube fittings simply because they are specially compressed and instrumental.
SAE flareless tube fittings are also called Chunk type tube fittings whose layout has actually been used for over sixty several years all over the world in various applications in air, on theground or at sea.
A ridge of metal (A) has become raised previously mentioned the tube area into a height of no less than 50% in the thickness on the ferrule’s main edge, totally round the tube.
The end on SAE flareless fitting nuts is usually a dim graphite coloration resulting from lubricant coating. The fitting nut includes a bonded dry film lubricant which aids while in the installation course of action to cut back torque and stop galling.
In minimal to medium force applications, the most typical relationship kind is often a flared fitting. One flare SAE 37° would be the conventional in many hydraulic units. SAE requirements for the utmost tube wall thickness needs to be followed just before flaring the tube to match the fitting relationship.Â
"A" and "B" models (see tube sleeve drawings to view the "A" and "B" style sleeves). After machining and inspection
A bite kind fitting is sometimes incorrectly generally known as a compression fitting. Compression fittings are suitable for use with tender tubing and they are not interchangable with Chunk sort fittings!
The AN (Army-Navy) military services conventional requires tighter tolerances and defines all fitting sorts, the place the JIC makes use of AN specifications as The bottom line for their unique expectations and covers fewer dimensions.Â
Like all metal-to-metal tube fitting units, the SAE flareless is proscribed in the quantity of disassemblies and reassemblies the tubing can withstand as being the ferrule bites deeper and deeper into your tubing wall with Every single reassembly.

The complete on SAE flareless fitting nuts can be a dim graphite color on account of lubricant coating. The fitting nut provides a bonded dry film lubricant which aids within the set up process to reduce torque and forestall galling.
Flareless Tube Fittings encompass a human body, a one particular-piece ferrule, plus a nut are available in carbon metal, brass, and chrome steel. With a large number of configurations, there will certainly be a fitting which is ideally suited to fulfill the necessities of virtually any industrial software. On assembly, the ferrule “bites†into your outer area of the tube with ample toughness to carry the tube versus tension and seal the fluid, with no substantial distortion of The within tube diameter.
Note that from the SAE flareless fitting, the Chunk is equally as powerful on a stable bar as it really is around the medium to hefty wall tubing for which it absolutely was developed. Review this to mild duty instrumentation fittings (1 or 2 ferrule) which depend on mechanical swaging of your tube for holding electric power. In these fittings, given that the wall thickness increases, much less swaging action can be done making these kinds of fittings unsuitable for hefty wall tubing and large pressures.
1. A slight indentation around the close on the tube which indicates which the tube was completely inserted throughout set up.
SSP SAE flareless or “Chunk sort† tube fitting proven style and design is used all over the world for over sixty decades in many applications from the air, on ground, and at sea.
