How To Replace A Water Shut Off Valve Under A Sink

What happens here

Take the new brass ferrule and apply a small amount of pipe sealant, specifically 'MegaLock' thread sealant, around its outer surface. The video emphasizes putting the sealant on the ferrule itself, not the threads of the nut, because the ferrule is the component responsible for creating the watertight seal in a compression fitting.

Goal: Apply a thin layer of pipe sealant (MegaLock thread sealant) directly onto the new ferrule, ensuring the sealant is on the part that creates the compression seal, not the threads.

What they say

Got our new angle stop. So this is the feral. And I like to go with a little bit of mega lock right around that feral. I usually put it on my ring finger because that's what fits pipe dope thread sealant. And I know we're not putting it on threads, but this is actually the part of the compression fitting that makes the seal. I'll just put that on loose.
