Types of Tube Connector

Hose barb termination
Barbed fitting terminations hold on the inside diameter (id) of a tube. They are typically used with pvc, polyurethane, silicone and other rubber and plastic tubing. These types of connectors are designed for one-time installation, but if the tubing is flexible enough they can be removed. They are sized for tubing with inner diameters (id) from 1/16″ to 3/4″ and 3mm to 19mm. The 1/16″ and some 1/8” barbs have a shroud to provide extra strength. Many of cpc's sterile biopharmaceutical connectors, including parts of the aseptiquik® series, use the hose barb system. You'll also see this type of thread used for some of our everis® liquid cooling couplings.

Pipe thread termination
Pipe thread connectors are industry standard, threaded connections that use a tapered male into a tapered female thread and tighten on themselves to seal with the added help of pipe dope or teflon® sealants. This type of tube connector offers equipment manufacturers the flexibility of a threaded port that will accept many different connections as long as they are standard pipe thread connections. The most common types of pipe threads are npt and bspt but others are available — some of which can be found among our lineup of general purpose couplings and connectors.

John guest fittings
These fittings are typically used with 1/4″ and 3/8″ od semi-rigid and metal tubing in applications requiring low flow restriction on the internal diameter of the tubing. With this tubing connector type, the tube is inserted into the fitting and an o-ring seals on the external diameter of the tube. Mechanical retention is provided by internal retainers that also hold on the outer diameter (od) of the tube. These push-to-connect type fittings provide a tight connection but are designed to enable quick removal of the tubing if necessary. John guest terminations provide the combination of quick assembly and the use of the cpc quick connect and disconnect.

Polytube fittings
Ptf terminations are typically designed for use with semi-rigid tubing such as polyethylene, nylon, polyurethane, etc. This type of connector can also be used with flexible tubing as long as the ids/ods are compatible. Whereas hose barbs are inner diameter (id) dependent, ptf's are inner and outer diameter (od) dependent. They are sized for .100″ id x 5/32″ od, .170″ id x 1/4″ od, and .250″ id x 3/8″ od tubing and their metric equivalents. These connections have a smaller barb that is more easily removed from the tube and then backed up with a nut that compresses the tube onto the barb, similar to a hose clamp.

Soft tube fittings
This type of tube fitting is designed for flexible tubing applications where the tube is installed over a stem — an integral nut slides forward over the tube and tightens against the tubing and the stem as pull force is exerted. This fitting allows for easy tubing removal. They are inner and outer diameter dependent and sized for 1/4″ id x 3/8″ od and 3/8″ id x 1/2″ od tubing. You'll often see fittings like this used in healthcare, where medical tubing connectors need to be used in various types of flexible tubing.

Compression fittings
Designed for use with semi-rigid or rigid tubing, a compression fitting is used to connect tubing or hose to a system. The seal is made between the tubing and compression fitting by squeezing the tubing or hose against the ferrule and body of the compression fitting by tightening a nut to seal and hold. These types of tube fittings also offer free flow without internal flow restriction.

Material of Tube Connector

Aluminum
Lightweight and corrosion resistant. Aluminum is commonly used for plumbing and is the preferred fitting material for aluminum tubing. By itself, aluminum has low tensile strength and is used when high corrosion resistance is needed. It is alloyed with zinc, copper, silicon, manganese, and/or other metals to improve its strength and hardness.

Brass
Strong, durable, and corrosion resistant, with high temperature ductility and good conductivity. Brass is an alloy of copper and zinc, and is the most common tube fitting metal used in industry because of its machinability and its excellent performance properties. Brass fittings can have various protective or decorative finishes which should match the finish of the tubing.

Cast iron
Strong and highly abrasion resistant. Cast iron fittings and tubes are used primarily in building construction for sanitary, storm drain, waste, and vent tubing applications because of their resistance to abrasive materials like sand, gravel, solid wastes, and debris.

Copper
Extremely corrosion resistant with excellent conductivity. Copper fittings are important for many plumbing and heating applications, and are commonly used for residential water supply lines. Copper fittings are usually used in conjunction with copper tubing, and come in either soft or rigid forms. Soft or ductile copper is easily bent and maneuvered, and is the only type suitable for flare connections. Rigid copper is not bendable and requires directional fittings to go around corners and obstacles.

Steel
Durable and strong, with a high resistance to heat. Steel is an alloy of iron and carbon - it is commonly alloyed with other metals to improve its corrosion resistance and durability. It is used in both commercial and industrial applications for carrying water, flammable gases, and other fluids. Galvanized steel is coated with zinc for rust and chemical corrosion resistance. Carbon steel is alloyed with higher levels of carbon for increased durability and strength.

Stainless steel
Relatively strong with excellent chemical and corrosion resistance. Stainless steel is an alloy of steel that contains over 10.5% chromium, providing excellent corrosion resistance for sanitary applications and those dealing with aggressive fluids and materials.

How to Maintain Tube Connector

Clean the coupling area and use protective caps
A little care and preventive maintenance during daily use will extend the service life of hydraulic quick release couplings. Pre-cleaning the coupling area and using a suitable protective cap is a very small cost in terms of effort and time, but makes a significant difference in terms of long-term performance and durability.

Do not use tools that could cause damage and leaks
Quick release couplings are designed to operate without additional tools that could cause damage and compromise function. In particular, the release of residual pressure must be entrusted to an appropriate mechanism, as external intervention can lead to unwanted leaks and possible ground contamination.

Regular maintenance checks
Inspections should be carried out at regular intervals, depending on the application, in order to prevent complications during use.Recommended maintenance includes the following.Thorough cleaning of external componentsLubrication of the coupling area or moving parts with oil/grease compatible with the specific sealCoupling and decoupling testsChecking the correct tightening torque of the adapterChecking coupling and decoupling sealsCheck the level of hydraulic contamination of the circuit.

Replace quick couplings as required and in good time
Based on the test results, the replacement of quick couplings should be evaluated and planned in advance to avoid interruptions in daily operation due to inefficient or worn components.

How to Choose a Tube Connector

Electrical requirements
The first step in choosing the right connections for your device is determining the electrical current and voltage specifications for each contact. You must ensure that not only do you have the correct amount of connections but that those contacts are also capable of carrying the power needs of your system.

Adding new features
Determine whether further functionalities can or should be introduced to your connector after you've identified electrical requirements. Hybrid connectors are often custom made, however, if you have the opportunity to focus with a supplier to produce a hybrid connector that is tailored to your unique needs, it may be worthwhile.

Types of termination
The assembly procedure and the capability to secure a connector are both affected by termination types. Solder contacts are generally easier to seal from moisture penetration, although crimp contacts may provide superior field reparability.

Sealing the environment
Check the manufacturer's Ingress Protection rating for dust and water sealing at various depths and operational time frames if the connectors will be utilized in tough operating conditions. Make sure you know what your connectors will be used for.

Substance
Brass fittings with copper plating have a longer lifecycle and are more wear-resistant than other materials. Metal connectors are an alternative if lightweight is a concern. Plastics are ideal for single-use and throw-away applications.

Needs for Reliability
Now that you've looked at the electric, ending, closing, and availability of materials, it's time to consider how often your customer will connect and disengage the item throughout its life.

Mass production
Miniaturization is doing some amazing things right now, and you should enjoy its benefits whenever possible. Examine the features in each connector carefully, since they become increasingly critical as the current and voltage rise.

Assemblies and raw cable
It's time to specify the basic cable and the cable component after you've identified your connector. Because connectors are shrinking all the time, it's becoming more common to specify a little connector that won't function with the longer cable you want to use. To verify whether the cable and connector are compatible, you'll need to look at them both together.

Inquire about customer and distribution channels
Check for practical delivery dates; unique connectors from any source will usually take longer to arrive than a standard product. If you can use anything that has already been designed, the delivery time will be reduced.

Engineering assistance can help you save time
Inquire about the technology product development support you may expect from vendors. Find out more about the design and fabrication services that are available.
