Review on 🔧 Hilitchi 150-Pcs Assorted Automotive Self-Centered Bonded Seal Oil Washers Gasket Kit [7 Sizes] by Jere Mosley

I have several bolted connections on an old diesel tractor that just won't stop leaking. I've tried a few copper washers, added a regular O-ring, etc. etc. Nothing helped. Until I got these! They "thread" onto a banjo bolt for a tight fit, and then unscrew them. Since then not a drop has spilled! I love them, it's a shame I didn't know them sooner.
