Not Worth the Investment

As a result of using this product in my industrial and scientific line of work, I found that it was not effective at all. The ring was not durable and tore easily, making it a total waste of money..

Pros
  • none
Cons
  • not durable

Good heavy rubber

This o-ring is just what I needed for my kayak storage coupe . It is made of good rubber and has a good seal to prevent water ingress. Would buy again!

Pros
  • Can be used in a wide range of temperatures from -30 degrees F (-34 degrees C) to 250 degrees F (121 degrees C)
Cons
  • Great price
