Mess Stopper™ Hydraulic Oil Service Plugs, 2 Large, 4 Medium, 8 Small Sizes, Round

I have only used these a few times, but they seem to work really well. Great for a quick plug of a hydraulic line, and sure saves time over digging through the bucket of assorted plugs.

Great product. Highly recommend. Has saved me from making huge messes but not having lines plugged

Not sure how I did without these for so long. Actually I used bolts, pins, pens, and anything else for normal hoses. When it came to hydraulic lines with metal connections I would use vacuum plugs and other odd and ends.First of all, the color! These are easy to see and even if they get soaked in hydraulic oil they stay bright. I have used these 1/2 dozen times from tractors to small engine repair, they work great.Second and most important, they work. You may have to swap to different sizes but all in all they seal good. I have no problem leaving these in for days while waiting on parts. I have yet to have one cone out when it wasn't suppose to.And last, professional. They just look good, with makeshift stoppers there is always a chance for contaminates or damage. With these they wipe clean and I haven't had any damage to them.

Should work great

These are great when your working with hydraulic hoses. Keeps oil from dumping all in my truck bed and work great for plugging just about anything else like brake lines and coolant hoses. Not to be used for anything with pressure behind it though

Finding the right plug size was always a struggle when disconnecting coolant and oil lines. These solve that problem and have a great seal. Highly recommend for automotive repair.

I work on cars here and there so once in a while I need to plug transmission lines or something similar and these were a great deal for what they are. I'm using these as an alternative to cap-plugs and since these are cone shape, they have a much wider range of uses and applications.

Work perfect!
