💡 How to Use This Chart:

1. Are you using a “Push-In” (Quick-Connect) Fitting?

Look at the OD (Outside Diameter). The tube must match the fitting size exactly.

  • Warning: A 1/4″ (6.35mm) tube will not fit correctly into a 6mm Metric fitting. They look similar but will leak!

2. Are you using a “Barbed” (Hose-Tail) Fitting?

Look at the ID (Inside Diameter). The “hole” of the tube must stretch over the ridges of the barb.

  • Pro-Tip: If the fit is tight, dip the end of the tube in hot water for 30 seconds to soften the plastic before pushing it onto the barb.

3. Are you using a “Jaco” (Compression) Fitting?

These fittings use a nut and a small plastic sleeve (ferrule). You must match the OD of the tube to the nut size. These are most common on Brine Tanks and older RO systems.

Description

A high-precision 6mm Nylon dosing tube engineered for critical chemical metering and high-pressure fluid transfer. Unlike standard flexible PVC, this Nylon construction offers superior structural rigidity and advanced chemical compatibility, making it the professional choice for handling aggressive additives and maintaining precise flow rates.

Uses & Applications:

  • Precision Chemical Dosing: Ideal for high-accuracy automated metering systems.

  • Aggressive Fluid Transfer: Specifically designed for acids, alkalis, and industrial solvents.

  • Outdoor Installations: Perfect for lines exposed to direct sunlight or harsh weather.

  • Pneumatic Signal Lines: Suitable for low-to-medium pressure air logic and control systems.

Benefits:

  • High Chemical Resistance: Compatible with a vast range of harsh industrial fluids that would degrade standard plastics.

  • UV-Stabilized: Carbon-black pigment protects the polymer chain from sun damage, preventing brittleness and cracking.

  • Structural Integrity: The rigid nature of Nylon maintains a constant internal diameter, ensuring dosing accuracy remains consistent.

  • Pressure Rated: Features a significantly higher burst pressure rating than standard flexible PVC or PE tubing.

Compatible Systems:

  • Pumps: Standard 2.2L/hr (and higher pressure) Peristaltic Dosing Pumps.

  • Fittings: 6mm Metric Quick-Connect (Push-in) fittings.

  • Barbs: 4mm Metric barbed hose-tail connectors.

Size & Dimensions:

  • Outer Diameter (OD): 6 mm

  • Inner Diameter (ID): 4 mm

  • Length: Sold per meter

  • Weight: ~0.03 kg per meter
