Plastic Isolator

09/09/2010 12:05 PM

I need to find various sizes of the same type of plastic isolators. These isolators are used when connecting a particular type of valve (butterfly valve) to a flange. Connecting both items using stainless steel bolts. The idea is to not have the bolt touch the valve or flange, thus isolating the dissimilar metals.

I have included 2 pictures of similar products we salvaged from a recent job.

Thank you for your help!!

I think this may be what you need instead of trying to piece together a one-of-a-kind plumbing problem-wating-to-happen.

not large enough I'm sure. I suspect this is for pipeline cathodic protection system isolation.
