Bottom Drain Mash Tun Silicon gasket

[DrPhilGood]

Hey Guys, so I am thinking of converting my mash tun to a bottom drain via the sanke neck with tri-clamp fittings and I was wondering what is the best gasket to use for this. I have currently, https://www.brewershardware.com/Silicone-Sanitary-Gaskets/ but it doesn't seem to fit that perfect. Is there another gasket that is more appropriately fitted for a sanke neck other then this one?
