Food Grade NSF FDA RTV Silicone Sealant Adhesive Red High Temp 10.3oz (Standard Version) (Standard Version)

Is this product food grade safe? Can it safely come into constant contact with food? And is this product bpa free?

Will this seal a hole in bricks? I want to drill a hole for a drain pipe through bricks will this seal around it? Does it dry hard?

Can I use this as a sealant for a 3D printed item that will have a mason jar affixed to each side filled with water?

Will this work on vinyl?
