However, there are some downsides. Teflon will tend to move away from an applied load (such as a compression ferrule) over a period of time. KYNAR is a trademark of Arkema. Western Tapered 3/16 to 3/8 Hose Barb, M24-12. A disadvantage of Teflon is its propensity to cold flow. These are straight threads (not tapered like pipe threads). Read on to learn more about the individual fitting styles. This interference creates the seal and also secures the tubing so it cannot slide out of the fitting. An o-ring or other type of seal inside the fitting makes a radial seal on the outside diameter of the tubing. Compression fittings are more reliable than push-to-connect fittings and can take much higher pressures but are not as convenient in terms of connection and disconnection. In some designs the OD of the metallic tube may need to be grooved to accept the teeth of the collet. Numerous o-ring elastomers are available to handle a wide range of temperatures and chemicals. What they didnt teach you about fittings in engineering school.

A far superior sealing method is to use a captured o-ring face seal. In contrast, barbed style fittings seal on the inside diameter of the tubing so they do not have to be as large as push-to-connect fittings. PEEK is a trademark of Victrex USA, Inc. The best line contact barb designs can withstand the full burst pressure of the tubing without failure. As you would expect, the most complex components are selected first. Additionally, due to the tapered thread design, pipe threads do not allow for an easy way to position the outlet of elbow and tee fitting configurations. Products shown as available are normally stocked but inventory levels cannot be guaranteed, For screen reader problems with this website, please call 1-800-430-3376 or text 38698 (standard carrier rates apply to texts), Use with flexible tubing for water lines to tanks, hoses and more, Pair with a hose clamp for a more secure fit.

The G versions below will stay nickel-plated. Tightening of the compression cap or nut pushes the ferrule into the tapered angle in the fitting body and thereby compresses the ferrule onto the outside diameter of the tubing.

Until all the stock has been depleted, nickel-plated hose barbs may be shipped. Tubing can be scratched during removal as it slides by the metallic collet teeth. Barb style fittings also have smaller waterways than push-to-connects or compression fittings. Materials include but are not limited to Nylon, Polypropylene, HDPE and Kynar. Properly designed barbed fittings allow the tubing to be easily pushed onto the fitting but make it difficult to pull off.

However, the multi-barbs, of progressively larger diameter, may disperse the holding power of the tubing over a greater area.

Contact Beswick Engineering to learn more about choosing the best fitting design for your application. There are many design considerations when selecting tubing. Tubing clamps also prevent the internal pressure from lifting the tubing off the barb(s). ANVER fittings have been designed for vacuum or medium pressure line connections, and they are used in conjunction with ANVER wire reinforced vacuum hose and worm gear drive hose clamps. On the line contact barb fitting, the edge of the barb makes a line contact, as opposed to a surface contact, with the tubing wall. Compression fittings are a good choice for use with metallic tubing, such as stainless steel and copper, and also hard polymeric elastomeric tubing such as PEEK, nylon, Teflon, Kynar, and polyethylene. 2000-2022 Home Depot. A seal, usually an o-ring or gasket is required to prevent leakage from straight threaded fittings. Another important factor is the reliability of sealing. The collet teeth are moved away from the outside diameter of the tubing when the releasing collar is depressed and that allows the tubing to be pulled out of the fitting. Additionally, it is usually more difficult to push tubing onto a fitting designed with progressively larger barbs. Many customers use Teflon tubing with compression fittings since it is resistant to most chemicals and will handle relatively high pressures. This sealing method eliminates leaks, compensates for rough surface finishes in mating parts, provides greater installation torque (secure connection), eliminates the need for thread sealants, and greatly reduced assembly time. Compression fittings do not work well with softer tubing because the tubing must resist the compression of the ferrule. Tapered pipe threads are somewhat vibration resistant. Chemical compatibility with gas or liquid, minimum and maximum pressures, expected temperature extremes, need for rigid or flexible lines, ease of assembly and maintenance, and external environmental conditions will determine which tubing or hose to specify in the application. fittings hose itself cooler transmission line very About ANVER Corp. / International Dealers, Hose Barb, 1/4 NPT x 1/2 (12.7 mm) Hose, Hose Barb, 3/8 NPT x 1/2 (12.7 mm) Hose, Hose Barb, 1/2 NPT x 1/2 (12.7 mm) Hose, Hose Barb, 1/2 NPT x 3/4 (19.1 mm) Hose, Hose Barb, 3/4 NPT x 1/2 (12.7 mm) Hose, Hose Barb, 3/4 NPT x 3/4 (19.1 mm) Hose, Hose Barb, 1/4 BSPP x 1/4 (6.4 mm) Hose, Hose Barb, 3/8 BSPP x 3/8 (9.5 mm) Hose, Hose Barb, 1/2 BSPP x 1/2 (12.7 mm) Hose, All fitting threads meet standards fromDrySeal American Standard Taper Pipe Thread (NPTF), Meet functional requirements of SAE J512, American Society of Mechanical Engineers (ASME), and American Standards Association (ASA), National Pipe Taper (NPT) or metric sizes available.

You must know the specifications of the threaded port you will be installing the fitting into so that you can select the appropriate fitting. Compression fittings are typically used for higher pressure applications (from 150 psi upward) or when the cleanliness and/or temperature resistance of stiff tubing such as stainless steel, PEEK, Teflon, or Kynar is needed.Compression fittings consist of a fitting body, either a one-piece or a two-piece ferrule, and a compression cap or nut. Some fitting manufacturers offer metallic tubing supports that can be inserted into the inside diameter of softer tubing materials to insure that the tubing does not collapse when the ferrule is swaged into the outside diameter of the tubing. This is the old standard design and is still found in many industrial applications but has many disadvantages.

This distribution of force over a large area reduces the holding force and also increases the chance of leakage.
