Water
Exactly what I needed to stop water supply after taking dishwasher out

Capped water lines. Did not leak.
Cap Nuts Have Multiple Uses
Would RecommendI purchased this Cap Nut to keep the water from dripping from my water filter after I removed the water supply line. This worked excellent now I keep it in my tool bag and ready for the next use.
Life changer part!
We had some bozo techs leave our waterline to the dishwasher unhooked so we could install an electrical outlet to correct the former owners diy job. We needed a cap fast and Lowe’s had it in stock to save several days of leaking water until the installers came back to complete their work! Good to have a wide variety of hardware close by for emergencies!
The staff in the store are so unhelpful
