Tapered connectors feature a gradual conical shape that provides a progressively tighter grip as tubing is pushed further onto the connector. This design accommodates slight variations in tubing inner diameter, making them more forgiving and versatile than fixed-diameter barbed connectors. The tapered design also creates a more gradual transition, reducing stress on the tubing and creating a more secure, leakproof seal.
Choose the connector size range that encompasses your tubings inner diameter. For example, if your tubing has an ID of 6mm, select the S2 connector (5-7mm range). The tapered design will accommodate this size comfortably. For best results, the tubing ID should fall within the middle of the connectors range. If your tubing ID is at the extreme ends of a range, consider the next size up or down.
These tapered straight connectors are available in six comprehensive size ranges: S1 (3-5mm inner diameter), S2 (5-7mm), S3 (7-10mm), S4 (9-12mm), S5 (11-14mm), and S6 (13-16mm). Each size range covers multiple common tubing diameters, reducing the need for many different specific sizes.
Yes, these tapered 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) Push tubing firmly onto the tapered end, the further you push, the tighter the grip becomes, 3) For difficult connections, moistening the tubing end with water or appropriate solvent can ease insertion, 4) Push until you feel resistance and the tubing is securely gripped, 5) Test the connection by gently pulling to ensure it is secure 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 the taper. Generally, these connectors are designed for low to moderate pressure applications typical in laboratory settings (gravity feed, peristaltic pumps, etc.). The tapered design actually 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 connectors specified range.
Each size of tapered straight connector is supplied in convenient packs of 12 pieces. All six sizes (S1 through S6) come in 12-piece packs, making them economical for laboratories with diverse tubing needs.
Yes, these tapered 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.
