Thread Sealant

[ABGordon]

I am ready to install the thermocouple in my exhaust manifold. Saw somewhere that I should coat the threads of the sensor with high temp. sealant (1600F or higher). Been to 3 auto stores, searched the WWW, can't find this product. Any help?



Thanks

Permatex Copper Anti-Seize Lubricant. From NAPA.

I thought anti-seize and thread sealant were two different products, intended to solve two different problems.

I assume the attachment to the manifold is via pipe (tapered) threads. Tapered threads are pretty much self-sealing. The Permatex product I cited will provide some lubrication as the pipe threads are tightened. The main reason to use the Permatex Copper Anti-Seize Lubricant is that it will facilitate dis-assembly if needed. It's good to 1800º F.

If you read a can of Never Seize... it says for hydraulic leak sealing on threads. Illflem used it to seal fuel fittings etc. High temp stuff obviously would work best.

I use the Permatex Coper anti-seize and really like it. Have not had a problem with anything like manifold to turbo studs / bolts, thermocouple in pre turbo manifold, thermocouple in post turbo downpipe.



Good Stuff,
