Tapered connectors have a conical shape with gradually increasing diameter, providing a progressive grip that tightens as tubing is pushed further on. Untapered connectors have a cylindrical shape with consistent diameter along each end, providing uniform, predictable grip. Untapered connectors are often simpler to use and provide consistent performance, while tapered connectors can accommodate slight variations in tubing size more easily.
This designation indicates that the connector is designed to accommodate tubing with inner diameters ranging from 7mm to 13mm overall. However, since this is an unequal connector, the two ends have different specific diameters within this range to allow connecting tubing of different sizes. The exact end diameters are engineered to provide optimal grip for common size transitions within the 7-13mm range.
Yes, these unequal untapered 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 cylindrical end until fully seated, 4) For difficult connections, moistening the tubing end with water or appropriate solvent can ease insertion, 5) Ensure tubing is pushed on sufficiently to achieve full contact, 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 securely the tubing is attached. 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 work well with silicone tubing as well as other flexible tubing materials like Tygon, PVC, and polyurethane. The cylindrical design provides consistent grip on silicone tubing. Ensure the tubing inner diameter is compatible with the connector ends.
These unequal untapered straight connectors (Code 46153-J1) are supplied in convenient packs of 12 pieces, making them economical for laboratories with regular tubing adaptation needs.
Yes, these unequal untapered 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.
