Watch the video to learn the proper process for assembly and installation of non-adjustable parallel thread port ends, or follow the steps outlined below.
Step 1: Inspect the threads.
Start by inspecting the thread and sealing surfaces. They must be free of burrs, nicks, scratches, and any foreign material. You will not be able to achieve a proper seal if any of these are present. Also, if your fitting has a male port end that requires an o-ring, seal, washer, or retaining ring with o-ring make sure that there is one properly installed before moving to the next step.
Step 2: Lubricate the o-ring (if it applies).
For male port ends with o-rings, you will need to lubricate the o-ring using a light coat of system fluid or a compatible lubricant. This will allow the o-ring to smoothly transition into the port.
Step 3: Finger tight.
Screw the connector into the port until finger tight.
Step 4: Tighten to proper torque.
Use the torque values shown in the Assembly and Installation section of the Parker Catalog 4300.
Step 5: For port ends with o-rings or seals present, Inspect the assembly.
Make sure to check the finished assembly to assure that the o-ring is not visible and that the fitting is fully seated on the flat surface of the port.
By following these steps your non-adjustable parallel thread port end connections should be leak-free. To help you ensure that all of your hydraulic fitting connections are installed leak-free, Parker Tube Fittings Division has created a series of tube and port end assembly and installation videos for the most common hydraulic fitting connections, which will be shared on TFDtechConnect.com over the next couple of months. You can also find detailed assembly and installation information for port end threads and tube fittings in the Assembly/Installation section of our Catalog 4300.
