The Eaton Rynglok® axial swage fitting system is a high-performance, leak-free solution for aerospace hydraulic tube repair. This guide breaks down the Rynglok® installation procedure into six clear steps, ensuring proper swage installation whether you're using a new or used Rynglok® tool.
✅ Step 1: Mark the Tube
Use the RTSG0‑01‑SIZE Rynglok® marking gauge to apply two marks:
Positioning mark (for placing the sleeve)
Inspection mark (to confirm proper advancement after swaging)
These marks are critical for a correct Rynglok® fitting installation.
✅ Step 2: Position the Fitting
Slide the Rynglok® fitting ring over the tube, aligning it with the positioning mark. This ensures the tube swaging system compresses the ring precisely where it needs to be.
✅ Step 3: Select the Correct Rynglok® Tool Head
Choose the Rynglok swage head that matches your tube diameter and system pressure. Eaton color-codes these heads:
Make sure you're using the correct Eaton Rynglok® tool compatible with your Rynglok® repair kit.
✅ Step 4: Align the Assembly Tool
Connect the hydraulic Rynglok® tooling system to a pump. Position the jaws of the tool around the fitting, ensuring proper alignment to avoid premature wear or off-center swages.
✅ Step 5: Swage the Fitting
Pressurize the pump to 8000–8500 psi. The Rynglok® sleeve will be radially compressed over the tubing. This step is the heart of the Rynglok® tube swaging system.
✅ Step 6: Perform the Final Inspection
Use the RTSG0‑51‑SIZE inspection gauge to confirm that the fitting has been fully swaged:
The sleeve should fully cover the inspection mark
The gauge should slide easily over the sleeve
This ensures a leak-proof connection—a critical requirement in aerospace tubing systems.
