Review on 🧵 YEJI Black Thread Protectors with Premium Screw Design by Joseph Adaymiln

These are well made and flexible screw thread protectors. Good for this purpose, but also good for protecting the ends of air hose connectors. I bought these to cover the ends of my air hoses and air tools when not in use to keep dirt out. I will also use them as protective caps on metal rods in projects. Would buy them again.
