Re: Yanmar 2GM20F mixing elbow Pearson 31-2
3M, Locktite and Permatex all make a 'high temp gasket sealant' which I'd probably use rather than regular telfon tape.. I used it on our mixing elbow connections a year ago and it's holding up well.
Thanks, I'll look into alternative sealants. I was thinking that the exhaust would be cool enough by then, but now that you mention it, the joint is upstream of the water port in the mixing elbow.
