I use these to put over the air intake on my nail guns when I’m not using them to keep the dirt out of them, fits perfectly and works perfectly

The caps are not the greatest quality but for the price they worked very well. The rubble was pliable and leaked no vacuum when installed. These are a must for older cars where the rubber has already degraded and is allowing leaks. Replacing your caps with new will improve your engines performance and idle stability over leaky caps.

Ever since I've daily driven vintage vehicles I've had these vacuum caps installed. Occasional back fires would shoot any rubber caps sky high and leave me stranded. These vinyl caps act like they've been shrink wrapped to any vacuum tube you apply them to. They never dry rotted or split. The seal is perfect and will help to eliminate any vacuum leak you would otherwise pull your hair out with old rubber caps. I've ran these with turbocharged applications too, just use a small zip tie to lock them in place and you'll put 20 pounds of boost all day with confidence. Ill Never go with any other cap.

Good little Supply five different sizes, I've only used a few but they seem pretty tough, didn't rip.

Been using this same set for years, for vacuum, carburetor, water lines, etc. Finally lost enough of them I needed more. Ordered the same set I have had for years, great kit and very cheap.
