19-Pack (10 Assorted Sizes) 000# -7# Solid Rubber Stoppers

I didn't know how much I needed some rubber stoppers until I bought them. He's coming a variety of sizes and are very durable rubber.

Grate for plug coolant hoses

used 2. Buying just one is high and not knowing which size will seal the hole best seemed like loosing deal. Better than cork.

These black rubber plugs are very similar in size, 2 of each size. Not small enough for my needs. I would've preferred that there was only one and that they had done more sizes. Each one is marked on the top with a number )with 000 being the smallest size,) my photos contain pennies as a reference point.

When cleaning parts or testing parts to make sure they hold pressure, you honestly can't have enough of these rubber plugs sitting in the tool box.I've used these in a number of project and I'm quite happy with their performance.Yes, I would recommend these stoppers, just double check the specific size you need for your project, allowing room for a snug fit and you're good to go.

I needed something to stop the distilled white vinegar from the fuel tank while cleaning. I've got a 1984 Honda Magna VF700C and the sub-tank had about 40 pieces of rust blocking the fuel flow. I had thought my issue was a bad fuel pump and at first it was, but the core issue was that fuel was being blocked from inside the sub-tank. So I removed it and placed screws inside along with distilled white vinegar to clean it and used these stoppers which worked great. Then I used them on the main fuel tank to clean it also. I use the #1, #2 and #3 stoppers. Good quality for what I needed them for.

Has a strange oily surface coating when received. Maybe due to storage for a long period and composition of the product is aging over time. Doesn’t appear to affect usability but it is annoying when handling and you need to clean your hands.

They work.
