Review on 🔧 Vehicle and Tool Repair O-Ring Assortment - Performance Tool W5201 HNBR (270-Pc) with Organizing Case by Dave Hock

Viton Set of 180 pieces: This listing is misleading. They are NOT made in Switzerland, but in China. Like many cheap Chinese things, the quality is below par. In this case all o-rings have manufacturing lugs and will certainly leak in any application where the ID or OD is the sealing surface - in most cases I need an o-ring. The material isn't very malleable either and [if it's really Viton?] is likely to fail early on. Space shuttle disaster, anyone? Too bad I waited so long for her arrival and was so disappointed. Send these back. To make matters worse, AMAZON expects me to be paid to return unwanted, inferior product!
