Unequal straight connectors are essential whenever you need to join two pieces of tubing that have different inner diameters. This commonly occurs when connecting equipment with different port sizes, adapting between pump tubing and delivery lines, integrating components from different manufacturers, or modifying existing fluid systems. They eliminate the need for complex adapter assemblies and reduce potential leak points.
The size designations indicate the range of tubing inner diameters each end can accommodate. For example, 4-8/8-12mm means one end accepts tubing with inner diameter between 4-8mm, and the other end accepts tubing with inner diameter between 8-12mm. The tapered design allows each end to securely grip any tubing size within its specified range.
These unequal tapered connectors are available in three size combinations: R1 (4-8mm on small end / 8-12mm on large end), R2 (4-8mm on small end / 12-16mm on large end), and R3 (8-12mm on small end / 12-16mm on large end). These three combinations cover the most common tubing size transitions found in laboratory settings.
Yes, these unequal straight 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.
For optimal connection: 1) Cut tubing ends squarely, 2) Select the correct end for each tubing size, 3) Push tubing firmly onto each tapered end—the further you push, the tighter the grip becomes, 4) For difficult connections, moistening the tubing end with water or appropriate solvent can ease insertion, 5) Push until you feel resistance and the tubing is securely gripped on both ends, 6) Test connections by gently pulling before pressurizing the system.
The pressure rating depends on several factors including tubing material, tubing wall thickness, temperature, and how far the tubing is pushed onto each taper. Generally, these connectors are designed for low to moderate pressure applications typical in laboratory settings (gravity feed, peristaltic pumps, etc.). The tapered design provides better grip under pressure as the force pushes the tubing further onto the taper.
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 work well with silicone tubing as well as other flexible tubing materials like Tygon, PVC, and polyurethane. The tapered design provides excellent grip on silicone, which can sometimes be slippery with standard barbed connectors. Ensure the tubing inner diameter falls within the appropriate range for each end.
Each size of unequal straight connector is supplied in convenient packs of 12 pieces. All three sizes (R1, R2, and R3) come in 12-piece packs, making them economical for laboratories with diverse tubing adaptation needs.
Yes, these unequal straight 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.
