💡 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

Brine Tubing ⅜”OD x ¼”ID Clear (LDPE)

⅜-inch heavy-wall polyethylene tube designed specifically for water softener brine tanks. The thick-wall construction ensures the tube maintains its shape under the vacuum suction required for brine regeneration.

Uses & Applications: * Water softener brine draw lines

  • Heavy-duty RO concentrate (drain) lines

  • Nutrient delivery in hydroponic systems

Benefits: * Visual Monitoring: Clear finish allows for easy troubleshooting of air bubbles

  • Collapse Resistant: Reinforced wall thickness prevents pinching under vacuum

  • Chemical Stability: Highly resistant to concentrated salt (brine) solutions

  • Durable Service Life: Built to withstand frequent suction/discharge cycles

Compatible Systems: * Standard ⅜” Quick-Connect fittings

  • ⅜” Jaco (Nut & Sleeve) compression fittings

  • Domestic and Light-Commercial Water Softeners

Size & Dimensions: * Dimensions: ⅜” OD (9.5mm) x ¼” ID (6.35mm)

  • Length: Sold per meter

  • Weight: ~0.04 kg per meter

Brine Tubing ⅜” OD x ¼” ID

Available in: Clear (ID: 1152) | Black (ID: 1142)

  • Standard Size: 3/8″ Outside Diameter | 1/4″ Inside Diameter

  • Wall Thickness: 1.58 mm (Heavy-Wall)

  • Description: A specialty polyethylene (PE) tube with a thicker wall than standard RO tubing. It is specifically engineered to handle the suction and discharge cycles of a water softener brine valve.

  • Uses & Applications:

    • Brine Draw: Connects the brine well in a salt tank to the control valve head (e.g., Fleck, Clack, or Runxin valves).

    • RO Waste Lines: Used as a durable drain line for under-sink RO systems.

  • Benefits:

    • Clear (1152): Perfect for troubleshooting; allows you to see if the brine is actually being drawn or if air bubbles are trapped in the line.

    • Black (1142): 100% UV-resistant and light-blocking. Essential if the brine tank is located near a window or outdoors to prevent algae growth in the salt water.

  • Connection Type: Fits 3/8″ Quick-Connect fittings or 3/8″ Jaco (compression) nuts.
