This is the good stuff from CORTECO, a genuine German-made high-temperature silicone sealant.

It's perfect for making gaskets on oil pans, valve covers, and intake manifolds.

It's rated to withstand temperatures from -70°C all the way up to +300°C, so it handles extreme heat and cold without failing.

It's oil-resistant, elastic, and comes in a standard tube.

This specific sealant matches a huge list of OEM numbers (like D000400, 12378479, and many more) and is trusted by professionals.

If you're assembling an engine and need a reliable, permanent seal, don't use cheap caulk.

Use this Corteco sealant and do the job right the first time.
