Sealing bulk head

[Aquattro]

I just drilled my frag tank and chipped the upper side of the hole, just a bit, but it spreads out past the gasket. Any thoughts on ensuring it doesn't leak? It's a 1" bulk head fitting. Thx

A good layer of silicone on both sides of the BH did the trick for me when I did the exact same thing.

I also had a spur on a 2" bulkhead when I drilled it out. I didn't worry about it. Just gobbed some silicone to ensure a good seal around the spur and have not thought about it since.

Might not hurt to use a larger gasket too?

When they fix windshields do they repair them with silicone? No, they use epoxy!!

That is usually for a crack I think. And also tempered laminated glass

I use silicone on my gaskets, but not silicone glue. The glue is a pain in the but to clean off. I use silicone gel from SCUBA shops (I am a diver and so have lots around). It is food grade, inert, and keeps the seal on 3000psi orings from leaking on my scuba tanks. It also allows easy r&r if you need to replace it later and it allows for some give (it is a lubricant) to rotate your bulkhead on the tank. I have it on several connection points in my tanks that I want to seal but also may want to remove later.
