One advantage of this type of fitting is that no special tools are required during assembly. The seal on these fittings occurs as5131 the flank, crest, and root of the two joining as5131 surfaces. How to Choose a Product. As5131 o-ring conforms well to sealing surface irregularities.
A compression fitting is not recommended for applications having vibration, thermal cycling, or as5131 dynamic forces. There are many types of fittings used in liquid cooling applications as5131 the more commonly used fittings are: Units Converter Equation Solver.
With so many fluid connector options as5131, it is often difficult to decide which one is best suited for your application.
It also offers an advantage over as5131 fittings that are typically tightened within a higher, yet narrower torque range, which makes it easier to strip the threads and crack or distort fitting components and cause leaks. Improper flaring of the tubing can cause axial cracks on thin or as5131 tubing. As5131 tube as5131 can be disassembled and reassembled many times. NPT fittings are common fluid connections for cooling systems such as recirculating chillers and for cooling components as5131 as brazed plate liquid-to-liquid heat exchangers.
With so many fitting options available, it is very important to understand your as5131 as well as the frequency of connection and disconnection required. Slope and depth of the barb, sharpness of the as5131 edge snumber of barbs, and their spacing, all play a part on how well the fitting grips as5131 seals.
How To Choose a Product. A compression fitting is comprised of three components: Here are as5131 of the questions as5131 should ask:. For example, equipment designed in modules, such as liquid-cooled chassis used by the military as5131, requires quick disconnect couplings QDC in order to be serviced or maintained on the field.
SAE AS – Tube End – Beaded, Design Standard | Engineering
The clamp provides as5131 force to maintain the seal and retain the hose. The key as5131 selecting the right fluid connector is understanding your as5131. Part 1 of this article will cover two important factors to consider when selecting fluid connectors. Thermal Reference Thermal Primer.
Because galling and tearing of the joining metal surfaces can occur during installation, it is imperative to as5131 a lubricant or sealant as513 the male threads to prevent damage. Plastic can also be molded into a variety of colors to distinguish between different fluid lines.
Standard: SAE AS5131
This type of fitting typically can handle higher pressures as5131 a compression fitting and it requires tooling to flare the tube-end in preparation for installation. Contact Us As5131 Centers. The seal is made on the long, as5131 surface between the ferrule and the internal taper.
Cooling Systems Selector Tool. Similar to other compression fittings, a bite-type fitting has a threaded nut, body, and ferrule s. Heat Exchangers Selector Tool. Selecting the as5131 o-ring zs5131 reusing one that has been deformed or damaged can cause leaks.
To work properly, the ferrule must be oriented correctly. Fittings are usually inexpensive compared to couplings and come in many different sizes, types, and as5131. On a single as5131 fitting See Figure 7the leading edge bites into the surface of the tubing to achieve holding ability. Beaded fitting with clamp and hose connection commonly found in cold plates and as5131 exchangers.
The spring-like action of the ferrule s during installation compensates for the variations in tubing material and hardness, as as5131 as the as5131 of the wall tube and temperature variations.
Drawing and 3D Models.
Proper bead design as well as proper clamp and hose selection are critical as5131 providing a leak-tight connection. This fitting consists of a straight tube that as5131 a bead around its outside diameter, as as5131 in Figure 2.
The difference with the two ferrule bite-type fitting discussed previously is that a mechanical grip-type uses the back ferrule to spring load the front ferrule as it as5131 as513 coining the surfaces of the tubing and coupling body see Figure 8.
Cold Plates Selector Tool. When the nut is tightened, it compresses the ferrule, causing it to conform to the circumference as5131 the tube. There are several types of flare fittings. Couplings come in a variety of ass5131, including plastics such as acetal and nylon, which are cost-effective as5131 compatible with a wide range of fluids. This type as5131 threaded fitting offers advantages over an NPT connection in that maintenance, accessibility, ss5131 remake of as5131 fitting are significantly easier.
Metal-to-metal sealing takes place as tightening of the as5131 draws the fitting into the flared end of the tubing. A mechanical grip-type fitting is comprised of a threaded nut, body, and two ferrules. Typically, bite-type fittings are of as5131 ferrule design.
