• Stops leaks at the union when worn or damaged nuts allow seepage
• Helps restore proper water flow to dispenser or ice maker when connection is the cause
• Works with compatible refrigerator water and refrigeration line unions

• One union hex nut

• Tip: loosen slowly and re-tighten by hand then wrench to avoid overtightening and damaging tubing
• If replacing a corroded nut, inspect the ferrule/sleeve and mating fitting and replace if damaged
