1/8″ Thread × 1/4″ OD Quick-Connect Elbow Fitting

This Quick-Connect Elbow Fitting is designed to connect a standard RO membrane housing port
(1/8″ threaded connection) to 1/4″ OD tubing. The 90-degree elbow shape helps create a clean, compact tubing
route in tight spaces under the sink or inside RO system setups.

Purpose

☑ Connects standard RO membrane / membrane housing ports to 1/4″ OD tubing

☑ Creates a 90° tubing turn to reduce bending and improve routing in tight areas

☑ Ideal for RO systems, countertop RO units, and water filtration applications using 1/4″ tubing

Key Features

☑ Quick-connect (push-to-connect) design for fast installation

☑ Compact 90° elbow shape for clean tubing management

☑ Helps reduce kinks and strain on tubing compared to sharp bends

☑ Compatible with most standard 1/4″ OD RO tubing

Installation Tips

☑ Use thread seal or plumbing tape (important!)
☑ Push tubing firmly into the fitting until it seats fully (you should feel it stop).
☑ Thread the 1/8″ side into the port by hand first, then tighten as needed (do not overtighten).
☑ Ensure tubing is cut straight and clean before inserting into the quick-connect end.
