🔧Installation Tips
Tubing Size
- Most RO systems use 1/4″ OD tubing (standard RO size).
- Some countertop RO systems and specialty setups use 3/8″ OD tubing.
- Tubing size refers to the outside diameter (OD) of the tube.
When Do You Need Elbow Adapters?
- Select 3/8″ OD Tubing if your system uses larger tubing.
- We include 2 elbow adapters to connect the inline filter to 3/8″ OD tubing.
✔ No tools required
✔ Push-to-connect installation
When Do You Need a T-Fitting?
A T-fitting (1/4″ stem x 1/4″ OD Tubing x 1/4″ OD Tubing) is helpful if you are:
- Adding the inline filter to an existing 1/4″ RO line
- Want an easier install with a clean branch connection
- Installing between tubing lines without reworking your layout
✔ Optional accessory
✔ Makes installation easier for some setups
Not Sure Which Option to Choose?
- If unsure, select 3/8″ OD Tubing. The filter comes with 1/4″ connections, and we include two elbow fittings for 3/8″ OD tubing in the package.
- Message us before ordering—we’re happy to help you pick the right fittings.
▶️ Video Installation Guidance
Because RO systems and plumbing layouts can vary, there are multiple valid ways to install an inline filter.
If you are unsure about your setup, we recommend:
- Searching YouTube for “inline RO filter installation”
- Watching a video that best matches your system type
(under-sink RO, countertop RO, post-filter installation, etc.)
Visual step-by-step videos can be very helpful and often make installation easier and faster.
