Gas Cylinder Connectors & Tube Fittings

Cylinder connectors are essential components used to connect gas handling apparatus, such as pressure regulators or pigtails, directly to high-pressure gas cylinders. These connectors enable the safe and efficient transfer of gases from the cylinder to the downstream equipment.

The actual design and configuration of the cylinder connector can vary depending on the type of gas stored in the cylinder. To ensure standardisation and safety, the Compressed Gas Association (CGA) has established a set of guidelines and codes known as CGA Connection Numbers. These codes specify the type of connector required for specific gases and help prevent accidental misconnections that could lead to hazardous situations.

There are three primary types of cylinder connectors, each identified by a specific CGA Connection Number:

(Diameter Index Safety System): CGA DISS connectors are commonly used in medical gas applications, particularly in hospitals and healthcare facilities. They are designed to prevent the accidental interchange of gas connections. Each gas-specific connector has a unique combination of pin positions and diameters, ensuring that only the correct gas can be connected.

CGA VCC (Vapor Cylinder Connection)

CGA VCC connectors are used for connecting vapor service cylinders, which contain gases in their gaseous state. These connectors typically feature a threaded design for a secure connection.

CGA VCQ (Quick-Connect Cylinder Connection)

CGA VCQ connectors are quick-connect types, allowing for rapid and easy attachment and detachment of gas equipment from the cylinder. They are often used in industrial settings for gases that can be safely handled in their gaseous state.

The typical construction of cylinder connectors involves a nut and nipple arrangement. The nipple is attached to the gas handling apparatus, and the nut is threaded onto the cylinder valve to secure the connection, preventing gas leaks.

It is crucial to use the correct cylinder connector and follow the CGA guidelines to ensure the safe handling and usage of gases. Misusing or interchanging cylinder connectors for different gases can lead to serious safety hazards, equipment damage, or contamination. Therefore, it’s essential to be familiar with the specific CGA Connection Numbers and their corresponding applications when working with gas handling apparatus and cylinders.

Tube Fittings Series

Also known as instrument pipe fittings or compression fittings, they are essential components used to connect and join tubing or pipes in various industrial, commercial, and instrumentation applications. These fittings are designed to provide secure, leak-free connections while allowing for easy installation and disassembly. They are widely used in industries such as petrochemical, oil and gas, chemical processing, pharmaceuticals, and instrumentation systems.

Due to their reliability and ease of use, tube fittings have become standard components in many industries where secure and leak-free connections are critical. They play a crucial role in various fluid and gas handling applications, enabling efficient and safe transportation of substances in complex systems.
