Description

Straight Quick-Connect Fittings (2-Pack) – 1/4″ OD Tubing × 3/8″ Thread

These Straight Quick-Connect Fittings are designed to connect 1/4″ OD tubing to components
with a 3/8″ threaded port, such as inline water filters, valves, and other water
filtration components. The straight design provides a clean, direct connection with minimal flow restriction. Some inline filters have a 3/8″ threaded port. This fitting allows them to be used with standard 1/4″ OD RO tubing.

Purpose

•  Connect 1/4″ OD tubing to 3/8″ threaded ports
•  Ideal for inline filters, RO membrane housings, valves, and water filtration systems
•  Provides a straight, low-profile tubing connection

Key Features

•  Push-to-connect tubing side for fast, tool-free installation
•  Straight connector design for clean, in-line tubing routing
•  Compatible with standard 1/4″ OD RO tubing
•  Suitable for potable water and RO filtration applications
•  Includes 2 straight quick-connect fittings

Installation Notes (Important)

The 3/8″ threaded side requires plumbing thread seal tape (PTFE/Teflon tape)
to ensure a secure, leak-free connection.
Wrap plumbing tape clockwise around the male threads before installation.
Hand-tighten first, then tighten slightly if needed. Do not overtighten.
Push 1/4″ OD tubing fully into the quick-connect port until it seats completely.
