they look great but.. i need extra long thread fittings because i'm going through 3/4 plywood as well as 3/8 tile and 1/2 glass lol

Unless you can stop the water it will interfere with curing. U could try using underwater silicone inside the tank around the outer edge. Then water pressure would push the silicone into the cracks rather than out.

Since you said the tank is plywood I would really look the hole over. If it's leakng around the rubber gasket then the wood is absorbing the saltwater and weakening as we speak.

Are you tightening the bulkhead nut onto the plywood?

Sch80 bulkheads do wonders, it's amazing so many people don't use them. Corse threads and thicker gaskets means a much tighter seal and they can take more pipe load. Try and find one that fits your hole better, there are many different brands that require different hole sizes. If you measure your hole myself or others can point you in the right direction. Thread depth shouldn't matter, the nut should butt up to the glass and you need a clearance hole large enough in you stand to clear the nut and allow access for tightening.

Is this how yours looks? If you notice, the holes in the plywood are much bigger than the bulkhead nut. Allowing for access, maintenance, and a tight fit to the glass.




If this is what you have done and its still leaking, then go for a sch80 bulkhead.
