☑ Provides a compact 90° connection for tight installation spaces

Key Features

☑ Push-to-connect design for fast, tool-free tubing installation

☑ 90° elbow shape helps prevent tubing kinks and sharp bends

☑ Compatible with standard 3/8″ OD RO tubing

☑ Suitable for potable water and RO filtration applications

Installation Notes (Important)

☑ The 1/4″ stem side inserts into a standard 1/4″ quick-connect port on an inline filter or membrane housing.
☑ The 3/8″ OD tubing side uses a push-to-connect fitting — ensure tubing is cut straight and inserted fully.
☑ If the 1/4″ stem is installed into a threaded port, use plumbing thread seal tape (PTFE/Teflon tape)
to ensure a secure, leak-free connection.
☑ Hand-tighten first and tighten slightly if needed. Do not overtighten.
