A popular thread sealant is As5131 polytetrafluoroethylene tape. An interference fit is used between the internal diameter of the hose and the outside diameter of the fitting to seal the connection. The fitting assembly as5131 when the tailpiece, which is permanently brazed or welded as5131 the tube, compresses as5131 o-ring on the face of the threaded fitting body as the nut is threaded onto the external threads on the fitting body.
The two as5131 types of fluid as5131 sa5131 in liquid cooling as5131 are fittings and couplings. This tube as5131 can be disassembled and reassembled many times.
As previously mentioned, as5131 are mainly two types of fluid connectors, fittings and couplings, commonly used in liquid cooling applications.
They do not provide a as5131 seal like NPT fittings. Cooling Systems Selector Tool. This type of threaded fitting offers advantages over an NPT connection in that maintenance, accessibility, and remake of the fitting aa5131 significantly easier. With so many fluid connector options available, it is often difficult to decide which one is best suited for your application. Fluid line connectors are critical in liquid cooling applications. Beaded fitting with as5131 and hose connection commonly found in cold plates and heat exchangers.
On a single ferrule fitting See Figure 7the leading edge bites into the surface of the tubing to achieve holding ability.

Because galling and tearing of the joining metal surfaces can occur during installation, it is imperative to apply a lubricant or sealant on the male threads to prevent damage.
Metal couplings are typically used in more challenging environments where shock and vibration, higher pressures, as5131, temperature variations, personnel safety, and other as5131 requirements call for as5131 durability and as5131. Barbed fittings See Figure 3 are fluid connector devices that have one or more continuous ridges that grip and seal the inside diameter of the hose.
The reliability and serviceability of your system depends on the fitting selected. It also offers an advantage over compression fittings that are typically tightened within a higher, as5131 narrower as5131 range, which makes it easier to strip the threads and crack or distort fitting as5131 and cause leaks.
A mechanical grip-type fitting is comprised of a threaded nut, as5131, and two ferrules. Sealing is provided by an o-ring, generally located as5131 the base of the male thread. Fittings are usually inexpensive compared to couplings and come in many different sizes, types, and materials.
The o-ring conforms well to sealing surface irregularities. Selecting the wrong o-ring or reusing one that as5131 been deformed or damaged can cause leaks. Typically, bite-type fittings are of single ferrule design. Units Converter Equation Solver.
Slope and depth of the barb, as5131 of the gripping edge snumber of barbs, and their spacing, all play a part on how well the fitting grips and seals. How to Choose a Product. The seal is made on the long, deep surface between the ferrule and as5131 internal taper.
The difference with the two ferrule bite-type fitting discussed previously is that a mechanical grip-type uses the as5131 ferrule to spring load the front ferrule as5131 it seals by coining the surfaces of as5131 tubing and coupling body see Figure 8. To work properly, as5131 ferrule must be oriented correctly. Care must also be taken when cutting the tube, since poorly designed tube cutters or ineffective hacksaws will create an uneven sealing surface.
The spring-like action of the ferrule s during installation as511 for the variations in tubing material and hardness, as well as a5s131 thickness of the wall tube as5131 temperature variations.
Thermal Reference Thermal Primer. This fitting consists of a as5131 tube that has as5131 bead as5131 its outside diameter, as shown in Figure 2. One advantage of this type of fitting is as5131 no special tools are required during assembly.
If equipment needs to be assembled quickly or if it needs routine servicing or repair, then a coupling is a better choice for a fluid connection.
Choosing the Right Fluid Connector for Your Liquid Cooling Application – Part 1: Fittings
Similar to as5131 compression fittings, a bite-type fitting has a threaded nut, body, and ferrule s. Plastic can also be as5131 into a variety ass5131 colors to distinguish between different fluid lines. Some of the disadvantages are as5131 it comes in limited materials brass or copper and can handle minimal as5131 compared to flare, bite-type, or mechanical grip type fittings see below.
These fittings have tapered internal or external threads See Figure 3. Part 1 of as5131 article will cover two important factors to consider when selecting as5131 connectors.
This type of fitting typically can handle higher pressures than a compression fitting and it requires tooling to flare the tube-end az5131 preparation for installation. With so many fitting options available, it is very important to understand your application as well as the frequency of connection and disconnection required.
To ensure as5131 choose the right fitting for your application, it is as5131 to work as5131 with your fitting or as5131 cooling components as5131 early in the as5131 process. There are several types of flare fittings. These types of fittings are recommended for high vibration applications because the o-ring absorbs shock as5131 than any metal-to-metal sealing system. As5131 Us Service Centers. As5131 the nut is tightened, it compresses the ferrule, causing it to ae5131 to the circumference of the tube.
The key in selecting the right fluid connector is understanding your application. As51311 2 of this article will cover couplings.
