Luer Lock
Luer Lock vs. Push Fit: Why It Matters
Push-fit connectors are common but prone to leaks and air intrusion. Luer lock fittings, by contrast, create a secure mechanical seal that resists pressure changes and ensures air-tight performance—essential for accurate dosing in sensitive reef systems.
Secure Luer Lock Connections for Leak-Free Dosing
Designed for long-term durability and safety in reef and freshwater aquariums.
The koralDose 4H uses Luer lock fittings to ensure every tube connection is precise, secure, and leak-proof. Unlike traditional push-fit connectors, Luer locks offer consistent performance and prevent air bubbles from entering your dosing line. Whether you’re dosing calcium, magnesium, or trace elements, you can trust that every drop reaches your aquarium accurately.
