Description
RO Tubing 1/4 inch is the flexible polyethylene (PE) tube used to connect every part of a home reverse osmosis system: pre-filters, membrane housing, pump, storage tank, post filter and faucet. The same tube is used for fridge water lines, ice makers, coffee machines and water dispensers. It is food-grade, light, flexible and works with all standard 1/4 inch push-fit fittings.
Colour coding
Using different colours makes installation and servicing easier:
- White – general use and purified water lines
- Blue – feed water or product water, by your own convention
- Red – drain line, so it is never confused with drinking water

Installation tips
Cut RO Tubing 1/4 inch squarely with a tube cutter, not scissors, so it seals in push-fit fittings. Push it in fully until it stops, then pull gently to confirm grip. Avoid sharp bends and keep tubing away from hot pipes. Replace old, yellowed or cracked tubing during servicing. Matching fittings are in our RO spare parts and accessories range. For background, see Wikipedia.
Frequently asked questions
Can I use it for hot water? No, standard PE tubing is for cold water only.
