Installation Tips

Tubing & Quick-Connect Notes

• Common RO tubing sizes are 1/4″ OD and 3/8″ OD.
• Cut tubing with a clean, straight 90° cut for the best seal.
• Push tubing fully into the fitting until it stops, then pull back gently to confirm it locks.

Important Use Notes

• Use with cold water only.
• For best performance, install as the final stage after the RO membrane.

Not Sure Which Option to Choose?

• • If unsure, select Universal Fit (includes 4 elbow adapters for 1/4″ & 3/8″ OD Tubing Connection)
  • Message us before ordering—we’ll 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.

• Search YouTube for “inline RO filter installation”
• Choose a video that matches your system type (under-sink RO, countertop RO, post-filter installation, etc.)

Visual step-by-step videos can make installation easier and faster.
