Frequently Asked Questions Cross Connectors

Cross connectors provide a single, compact connection point for four tubing lines, which is more space-efficient and creates less dead volume than using multiple T connectors joined together. They also reduce the number of potential leak points in a system, as you have one connection point instead of multiple interconnected fittings. This makes them ideal for applications requiring precise fluid handling and minimal dead volume.

These cross connectors are designed for use with flexible tubing having the corresponding inner diameter: 6mm connectors (Code 46121) are for 6mm ID tubing, 8mm connectors (Code 46122) are for 8mm ID tubing, and 10mm connectors (Code 46123) are for 10mm ID tubing. For optimal leakproof performance, use tubing with the exact matching inner diameter and ensure it is pushed fully onto the connector.

Yes, these cross connectors are manufactured from polypropylene, which is autoclavable at standard sterilization temperatures (121°C). This makes them suitable for sterile applications in microbiology, cell culture, and pharmaceutical settings. However, always ensure that any tubing attached is also autoclavable and compatible with the sterilization process.

These connectors achieve leakproof joints through precision-engineered barbed ends that create multiple points of contact with the inner wall of flexible tubing. When tubing is pushed onto the connector, the barbs compress the tubing material, creating a secure mechanical seal that resists both pull-out forces and internal pressure. The design ensures consistent, reliable sealing across all four ports.

The pressure rating depends on several factors including tubing material, tubing wall thickness, temperature, and the security of the connection. Generally, these connectors are designed for low to moderate pressure applications typical in laboratory settings (gravity feed, peristaltic pumps, etc.). For high-pressure applications, we recommend testing under your specific conditions or consulting with our technical support team.

Polypropylene offers excellent chemical resistance to aqueous solutions, dilute acids, dilute bases, alcohols, and many organic solvents including acetone, ethanol, and methanol. However, it may not be suitable for strong oxidizing agents, concentrated acids, chlorinated solvents (like chloroform or dichloromethane), or aromatic hydrocarbons (like toluene or xylene). Always consult chemical compatibility charts for specific applications.

Yes, these connectors can be used with standard peristaltic pump tubing of matching inner diameter. However, ensure that the tubing is pushed fully onto the connector to achieve a leakproof joint. The connection should be secure enough to withstand the pulsatile flow and pressure generated by peristaltic pumps.

Each size of cross connector is supplied in economical packs of 36 pieces. Code 46121 (6mm) comes in packs of 36, Code 46122 (8mm) in packs of 36, and Code 46123 (10mm) in packs of 36. This bulk packing ensures laboratories have adequate supplies for multiple setups and complex manifold systems.

For optimal leakproof performance: 1) Cut tubing ends squarely, 2) Push tubing firmly onto each connector end until fully seated, 3) For difficult connections, moistening the tubing end with water or appropriate solvent can ease insertion, 4) Ensure all four connections are secure before pressurizing the system, 5) Periodically check connections, especially if tubing ages or becomes brittle.

Yes, these cross connectors are manufactured from polypropylene material conforming to US FDA 21CFR standards, making them suitable for direct food contact applications. This compliance ensures they meet strict safety requirements for food processing, pharmaceutical, and clinical laboratory use.
