Frequently Asked Questions L Connectors

Bending tubing, especially at sharp 90-degree angles, can cause kinking, which restricts flow and can eventually lead to tubing failure or cracking. L connectors provide a smooth, controlled 90-degree turn that maintains full internal diameter throughout, ensuring unrestricted flow and preventing kinking. They also create a more professional, organized appearance and make it easier to route tubing in tight spaces.

These L connectors are designed for use with flexible tubing having the corresponding inner diameter: 6mm connectors (Code 46131) are for 6mm ID tubing, 8mm connectors (Code 46132) are for 8mm ID tubing, and 10mm connectors (Code 46133) 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 L 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 L connectors feature 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. This design ensures consistent, reliable sealing in any orientation.

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.

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 connection. The connection should be secure enough to withstand the pulsatile flow and pressure generated by peristaltic pumps.

Each size of L connector is supplied in economical packs of 36 pieces. Code 46131 (L-6mm) comes in packs of 36, Code 46132 (L-8mm) in packs of 36, and Code 46133 (L-10mm) in packs of 36. This bulk packing ensures laboratories have adequate supplies for multiple setups and organized tubing 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 both connections are secure before pressurizing the system, 5) Periodically check connections, especially if tubing ages or becomes brittle.

Yes, these L 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.
