Tubing Connector
Product Code : EL-TT-10317
Quick answer: This is a white polypropylene, Y-shaped three-way tubing connector with riffled (ridged) ends that grip rubber or silicone tubing securely, used to join or branch flexible tubing runs on a lab bench — for example splitting a single vacuum or water line to feed two setups, or joining tubing between a condenser, aspirator or gas-delivery apparatus.
Why the Riffled End and Y-Shape Matter
The ridged (riffled) profile on each arm bites into the inside wall of rubber or silicone tubing as it is pushed on, resisting slip and blow-off under normal vacuum or low-pressure gas and water flow — a smooth-walled barb by comparison relies on friction alone and works loose more easily. The three-way Y layout lets one tubing run be split into two branches (or two runs joined into one) without cutting into glassware, which is useful when a single water aspirator or vacuum line needs to feed two pieces of apparatus at once. Polypropylene construction resists most common laboratory solvents and does not react with typical aqueous reagents, making it a practical, low-cost alternative to a glass Y-connector where the connection does not need to tolerate direct heat.
Frequently Asked Questions
What tubing sizes fit this connector?
The riffled ends are sized for standard laboratory rubber and silicone tubing bores commonly used with vacuum, water and gas lines; confirm the exact internal diameter of your tubing against the connector's arm size at enquiry stage to ensure a secure fit.
Can this connector be used with gas lines as well as water or vacuum lines?
It is suitable for typical low-pressure laboratory water and vacuum tubing applications. For gas services, confirm compatibility of polypropylene with the specific gas and pressure involved before use, since some gas applications call for a different material or a dedicated fitting.
Why choose a plastic Y-connector instead of a glass one?
A polypropylene connector is lighter, will not shatter if dropped, and costs less than an equivalent glass Y-piece, making it a practical choice wherever the connection point does not need to withstand direct flame or high heat.
