• Secure Metal-to-Tube Seal: Compression design ensures a reliable, leak-free connection.
• Compact 90° Elbow Shape: Facilitates tight routing in compact systems.
• Threaded to Tubing Transition: Efficiently links threaded ports to tube lines without adapters.
• OEM-Grade Compatibility: Designed to work seamlessly with Graco lubrication and spraying setups.

Installation Instructions

1. Cut the 1/4″ tube squarely and deburr it to avoid damaging the ferrule.
2. Slide the compression nut and ferrule over the tube before inserting it into the fitting.
3. Thread the elbow into the 1/8″ NPT port by hand, then tighten using a wrench to Graco’s recommended torque.
4. Pressurize the system gradually, then inspect for leaks and re-check after a few cycles.

When to Use This Fitting

• When you need to make a 90° connection from a 1/8″ NPT outlet to a 1/4″ tubing line.
• When retrofitting or repairing lubrication points in Graco automatic systems.
• When compact, OEM-quality connections are required in tight or panel-mounted assemblies.
• When minimizing leak risk with a robust compression seal.
