Tube connectors are used to connect tubes.
The most commonly used type is the taper type, which is inserted into the tube and tightened. The easy-to-handle push-one type is used for gases such as high-pressure air. Other Swagelok type tubes and tubing connectors are also available for lowering leakage.
There are straight, T-shape, Y-shape, L-shape, and irregularly shaped types, which are selected and combined according to the system.
Tubes are used to flow liquids and gases. Tube connectors are used to connect and branch tubes, to connect tubes of different diameters, and to connect tubes and equipment.
When non-corrosive liquids are used, inexpensive tube connectors can be made of any material. However, when acids or alkalis are used, the material of the connector must be carefully selected along with the material of the tubing to prevent corrosion. Corrosion can lead to leakage of liquid and accidents, so appropriate materials must be used. Polypropylene resin is often used as a material, but when used for highly corrosive liquids, fluoroplastic material with high corrosion resistance is chosen.
Since tube connectors are used to connect tubes, they are designed in various ways to prevent leakage. The most leak-resistant type of tube connector is the Swagelok type, which uses a ferrule to tighten the connector firmly so that there is almost no leakage. Conversely, the connector type that leaks easily is the push-one type, which does not require tightening and is convenient. This type is used for high-pressure air and high-pressure nitrogen. It is used for air guns and other inexpensive, easy-to-use tubing connectors.
Tubes are made of vinyl, silicone, PCV, etc., and the material of the tubing connector should match the tube material as closely as possible. In particular, it is best to be careful when using joints, as they are prone to leaks and other defects. In addition, when connecting tubing with different outside diameters, it is necessary to consider the possibility of reduced flow or changes in the flow rate. Please pay attention to these points when using tube connectors.
