Review: THESE WORK GOOD AS ENGINE VACUUM CAPS TOO! - As long as they don't see constant oil they shouldn't swell up and keep sealing mint with temperature!

### ⭐⭐⭐⭐⭐ Good Selection, I'm Using These to Cap Scissors & Pointy Tools
*by C***L on December 17, 2025*

Rather than cap hosing, I am using these to cap scissor points and other "pointy" tools after failing to find other solutions. I like the size selection, although I am using the mostly smaller sizes, and have plenty left over for future uses.
