The 3/8" high-pressure water filter tubing - the larger format LLDPE tubing for commercial RO installations and high-flow circuits where 1/4" creates flow restriction.

When to Use 3/8" Instead of 1/4"

3/8" tubing has roughly 2.5× the cross-sectional flow area of 1/4" tubing - at the same pressure, it carries proportionally more water without significant pressure drop. This matters in:

  • Commercial RO systems at 400+ GPD output
  • Pump-tank inlet and outlet lines - pumps typically have 3/8" NPT ports
  • Whole-house filter feed lines between mains and primary filter
  • Drain and reject lines on commercial RO with higher reject volumes
  • Multi-stage commercial pre-treatment linking between large cartridge housings

For anything residential, 1/4" tubing is fine. For commercial and high-flow, 3/8" is the right answer.

  • NSF/ANSI 42 - aesthetic effects (taste, odour, chlorine)
  • NSF/ANSI 58 - reverse osmosis system components
  • NSF/ANSI 61 - drinking-water system components, health effects

Material and Specifications

  • Outer diameter: 3/8"

  • Material: LLDPE (Linear Low-Density Polyethylene)

  • Maximum temperature: 45°C

  • Application: commercial RO, pump-tank circuits, whole-house feeds, high-flow installations

Length Options

  • 5m - single commercial RO install
  • 10m - commercial RO with pump-tank circuit
  • 20m - installer pack for multi-job
  • 50m - trade roll for commercial installer stock

Installation Cautions

Same as for the 1/4" tubing:

  • Maximum 45°C - keep away from fire and high-temperature areas
  • Don't bend at sharp 90° angles (use elbow fittings)
  • Inspect surface before use
  • Cut off used portion before reuse
  • Avoid direct sunlight (UV degradation over time)

Key features

  • 3/8" high-pressure water filter tubing
  • LLDPE material - same as 1/4" tubing, sized up
  • Suits commercial RO, pump-tank, high-flow installations
  • Available in 5m, 10m, 20m, or 50m lengths
  • Maximum temperature 45°C
  • ~2.5× the flow capacity of 1/4" tubing at the same pressure

Recommended for

  • Commercial RO installations at 400+ GPD output
  • Pump-tank inlet and outlet circuits
  • Whole-house filter feed lines
  • Commercial RO drain and reject manifolds
  • Multi-stage commercial pre-treatment
