Reverse Osmosis Tubing Sizes: A Comprehensive Guide

Understanding RO Tubing Sizes and Types

Reverse osmosis (RO) is a water purification process that uses pressure to force water through a semipermeable membrane, leaving behind impurities. The tubing used in RO systems plays a crucial role in the efficiency and longevity of the system. Let's delve into the common tubing sizes and types used in RO applications.

What Size is RO Tubing?

The size of RO tubing can vary depending on the specific application and the capacity of the system. However, the most common sizes are:

  • ¼ inch (6.35 mm) OD: This is the standard size for most residential and small commercial RO systems. It provides a balance between flow rate and pressure.
  • ⅜ inch (9.52 mm) OD: Larger systems, such as those used in industrial settings, often employ ⅜ inch tubing to accommodate higher flow rates.
  • ½ inch (12.7 mm) OD: While less common in residential setti...
