2. Specifications and Sizes

Copper barb connectors are available in a variety of specifications and sizes to meet the needs of different pipe connections. Common specifications and sizes include:

Pipe diameter

• Small pipe diameter: suitable for connecting hoses with smaller diameters, usually between 6mm and 12mm, suitable for connecting small pipes, such as laboratory equipment and small industrial equipment.
• Medium pipe diameter: suitable for connecting hoses with medium diameters, usually between 12mm and 25mm, suitable for ordinary industrial equipment and home use.
• Large pipe diameter: suitable for connecting hoses with larger diameters, usually above 25mm, suitable for large industrial equipment and municipal engineering.

Length and thread

• Length: The length of the barb connector varies according to the needs of the pipe connection, usually ranging from 20mm to 100mm, to ensure sufficient embedding depth and connection strength.
• Thread type: There are two types of metric threads and imperial threads. When choosing, you need to match them according to the thread standard of the pipe.

Working principles and advantages of copper barb connectors

Working Principle

The design of the copper barb connector is based on a simple and effective physical structure. Its main working principle is as follows:

1. Barb design: There are multiple barbs on the connector, which will embed into the inner wall of the hose after the connector is inserted into the hose. This design uses friction and mechanical bite force to ensure that the hose will not fall off easily.
2. Tight fit: The size and shape of the barb are precisely designed to fit tightly with the inner wall of the hose to form a strong connection. During the connection process, the barb slightly compresses the hose material, thereby increasing the stability of the connection.
3. Pressure distribution: When the barb of the connector is stressed, it will evenly distribute the pressure over the entire connection area of ​​the hose to avoid damage to the hose due to excessive stress at a single point.

Advantages

1. Simple physical structure: The design of the copper barb connector is very simple, and it mainly relies on the friction and bite force between the barb and the hose for connection. No complex mechanical devices or tools are required, and the operation is simple and efficient.
2. Strong connection: The barb structure provides extremely strong connection force to ensure that the hose will not fall off in high pressure or high vibration environments. This design makes it perform well in situations where high reliability is required, such as industrial piping systems.
3. Durability: Copper material has excellent corrosion resistance and durability, can be used for a long time in harsh environments, and reduces the frequency of replacement and maintenance.
4. Versatility: Suitable for a variety of hose materials, such as plastic pipes, rubber pipes and metal pipes, and can be applied to a variety of fluid media, including liquids and gases.
5. Easy installation: No special tools are required, and installation can usually be completed manually, which greatly saves time and labor costs and improves work efficiency.
6. Safety: The firmness and durability of the connector ensure the safe operation of the pipeline system and avoid leakage or other safety accidents caused by hose detachment.

How to choose the right copper barb connector

Choosing the right copper barb connector requires comprehensive consideration of the pipe material, size, and specific application scenarios. The following is a detailed selection guide:

1. Choose according to pipe material and size

Pipe material

• Plastic pipe: For plastic hoses, choose copper barb connectors with larger barbs to ensure a tight bite and prevent slippage.
• Rubber pipe: Rubber pipes are usually softer, so you can choose connectors with slightly smaller barbs to prevent damage to the pipe wall while still maintaining a secure connection.
• Metal pipe: Metal pipes require stronger connection force, so you should choose connectors with multiple barbs and precise dimensions to ensure stability and durability.

Pipe size

• Small diameter pipe: For pipes with smaller diameters, choose a suitable small copper barb connector, usually between 6mm and 12mm, to ensure that the connector can be inserted and fit tightly.
• Medium diameter pipe: Medium diameter pipes are suitable for medium-sized connectors, usually between 12mm and 25mm, to provide sufficient connection strength.
• Large diameter pipe: Large diameter pipes require large connectors, usually above 25mm, to ensure reliable connection under high pressure and high flow conditions.
