Dust Covers

In Dusty environment you better cover open pipes and hoses especially when working with vacuum pumps. Here are two standard pipe covers (pipe Out Diameter) 3/8" and 9/16" that I'm using in my shop. These covers have good grip and will protect you vacuum system. I added a small eyelet that will help you to tie each cap to the pipe so you will never have to search it all around.
