💡 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

Dosing Tube 8/5mm – Black (Nylon)

Full Description: A professional-grade, 8mm metric Nylon dosing tube engineered for high-performance chemical metering and industrial fluid transfer. Unlike standard PVC, the Nylon construction provides a higher burst pressure rating and exceptional resistance to “kinking” or “ovalization” under mechanical stress, ensuring a constant and precise flow rate.

Uses & Applications: * High-Output Dosing: Optimized for 7.1L/hr peristaltic dosing pumps.

  • Industrial Chemical Feed: Suitable for aggressive additives, cooling tower chemicals, and boiler treatment.

  • UV-Exposed Installations: Designed for outdoor chemical lines where sunlight exposure is frequent.

  • Pneumatic Signal Lines: Can be used in low-to-medium pressure air logic systems.

Benefits: * Total UV Protection: Carbon-black impregnated Nylon resists UV degradation and prevents brittleness over time.

  • Superior Chemical Compatibility: Highly resistant to a wide range of oils, fats, and corrosive industrial chemicals.

  • High Structural Memory: Maintains its internal diameter even when subjected to the constant “pinching” of dosing pump rollers.

  • Algae-Block Technology: 100% opaque wall prevents light penetration, keeping the internal bore free from bio-clogs.

Compatible Systems: * 7.1L/hr Peristaltic Dosing Pumps

  • Standard 8mm Metric Quick-Connect (Push-in) fittings

  • 5mm Barbed hose-tail connectors

Size & Dimensions: * Outer Diameter: 8 mm

  • Inner Diameter: 5 mm

  • Length: Sold per meter

  • Weight: ~0.04 kg per meter
