Para calcular a classificação geral de estrelas e a análise percentual por estrela, não usamos uma média simples. Em vez disso, nosso sistema considera coisas como se uma avaliação é recente e se o avaliador comprou o item na Amazon. Ele também analisa avaliações para verificar a confiabilidade.
Viton 180-piece kit: This listing is very misleading. These are NOT made in Switzerland, but China. Like many inexpensive Chinese things, the quality is sub-par. In this case the o-rings all have manufacturing ridges and will surely leak in any application where inner or outer diameter is the sealing surface - which is most applications I would need an o-ring for. The material is also not very pliable and [if they are really Viton?] most likely to fail early on. Space shuttle disaster, anyone? It's a shame I waited so long for these to arrive only to be so disappointed. Sending these back. What is even worse is AMAZON expects ME to pay for shipping back junk, inferior products!
Things are not worth it. Quality control is sure lacking. I had about 5 o rings that were already damaged. Some are not even the correct size. Avoid the frustration and divert to a better quality o rings.
