|I replaced both of the O-Rings with 5/8" ID x 13/16 OD standard O-Rings from a local NAPA store. The material was listed as Nitrile. I found the following information on a website and it would appear that this material would be okay for this application. Apparently Buna N would be okay (Petroleum Products). Any other thoughts on the Buna material? Should I find another replacement? Is the Nitrile (Buna N) is okay?
For those who may wonder what the plug looks like, I have included a photo of it.
The plugs pull right out. Maybe a little too easily but I guess that may be just an indicator that their sealing ability may have been depleated. The old O-Rings seened to be a bit soft.
Thanks for the help.
Nitrile (NBR or Buna N)
Due to it’s ability to be compounded for service over a temperature range of -65°F to +275°F, and it’s excellent resistance to petroleum products, Nitrile is the most widely used elastomer. Nitrile o-ring compounds can exhibit excellent compression set resistance, tear resistance, and abrasion resistance.
These compounds do not exhibit good resistance to ozone, sunlight or weather.
