A 3/8" straight push-fit joiner - the larger-format inline splice fitting for commercial RO and high-flow installations. Same basic function as the 1/4" version but sized for 3/8" tubing.

When You Need 3/8" Instead of 1/4"

3/8" tubing is the standard for higher-flow installations:

  • Commercial RO systems at 400+ GPD
  • Pump-tank inlet and outlet circuits
  • Whole-house filter feed lines
  • Drain and reject lines on commercial RO
  • Pre-filter to RO membrane connections on commercial units

Wherever 3/8" tubing is in use, you need 3/8" fittings - using 1/4" fittings with 3/8" tubing isn't an option (they won't fit), and reducing to 1/4" creates flow restriction at the worst point in the line.

Installation

  1. Cut both tube ends square (clean perpendicular cuts)
  2. Push first tube fully into one end of the joiner (engagement depth ~20-22mm)
  3. Push second tube fully into the other end
  4. Pull gently to confirm both ends are locked

No thread tape, no clamps, no tools - same Speedfit-style operation as the smaller 1/4" fittings, just sized up.

Where 3/8" Joiners Are Used

  • Inline repair of a damaged 3/8" tubing section
  • Tube extensions in commercial RO installations
  • Joining commercial drain or reject lines
  • Strategic splice points in larger installations

    “I had an issue with my caravan water filtration and the guys at Enviro Aqua got me sorted with a new system that is far better than my old one and for less than the cost of the previous filters alone. If you have to replace filters in your caravan, look here first.”
