Kodiak Brake Line Kit Leaking at 3/16" Union
Updated 02/17/2026 | Published 06/12/2024
Question:
Good afternoon. My customer purchased this hose kit for his trailer and being a foot too short I simply ran a hard line to make the difference. Im having an issue with the kodiak side leaking at the 3/16 union connection. I have tried replacing the union several times with no success. Any suggestions? Thank you

As the leak is not caused by the union you will want to check to see if the leak is from the flare on the Lines # 18SI-BLKIT or the actual hose connection. This will help you to determine if the hose needs to be completely replaced or if the flare needs fixed with a flare tool.
