Permanently Capping/Sealing a Radiator Pipe

I'm removing a radiator that's uselessly inside a kitchen cabinet. The floor is open and I can drain the system, disconnect the supply valve and return elbow, and cap the threaded pipes permanently. What's the best sealant to use if I never need that branch again? A sealant like RectorSeal or Blue Monster? Teflon tape? Something I've never heard of?

    Teflon tape,slic tite or other pipe dope is fine.

    The brand names you mention above are what you want to use. They're fine.
