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

We have a blow up pool and needed a plug for one of the holes since it got lost. This worked perfectly! It's sturdy enough to hold it while not sticking out to far. The price was perfect and just right so I don't feel like I'm spending to much money to fix something so small.

Sturdy plugs for our outside fountains

Nice set of rubber plugs. I used them to plug all the coolant hole in a small block chevy gen 1 engine to keep contamination out of the engine during a head gasket replacement. Worked perfectly when cleaning the block with scrapers and razor blades. Got another set of smaller ones that worked the same for the smaller holes. Used set screws in the head bolt holes. Plugs were easy to remove after cleaning using an icepick.

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.

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.

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.

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.
