Each of the solenoid assemblies have the same cable connectors. Use the fittings from the removed assembly to make the correct configuration for your machine. Refer to the image:
- Haas P/N 58-3600, NIPPLE 3/8 NPT X 1 7/16 HEX BRASS
- Haas P/N 58-3625, FITG REDUCER NPT1/2M NPT3/8F BRASS
Each 3-port solenoid manufacturer we use for the TRP has an inlet , an outlet , and an exhaust . When you install the replacement solenoid assembly, make sure you connect the new ports correctly. The locations of the port are different for different manufacturers.
Example: Replace this MAC assembly that has a pre-charge and a muffler  with this SMC assembly . Use the fittings from the replaced assembly  to make the new solenoid assembly .
note: More fittings are necessary for some solenoid assemblies. Refer to the notes before the illustration.
