Loctite 518 50ml Tube

Loctite 518 - 50ml. Anerobic sealant - cures in the absence of air. Mfg. rated to 300 degrees, but we think it seals effectively at much higher temperatures as well. Use this sealant for high heat applications. Especially useful on late bus copper exhaust gaskets - this product will help stop exhaust leaks on these difficult to seal heads. Many other uses. This is the most used sealant in our engine shop.
