O ring multi kit

Correct and of high quality. O-rings can be life or death, that is what failed on the Challenger space shuttle. Thanks for posting the link! If one wants to learn about O-rings there is no better reference than the Parker handbook. I used it a lot as a young engineering tech, later in life as national sales manager I was having major product issues in the field. The Parker handbook saved the day. Was stuck hanging in a hotel room nightly and used the Parker handbook to resolve the issue and get sales back up. All in the compound in that case. Every aspect of an O-ring is a variable, and every aspect can make a difference in the application.
