Double gaskets on bulkhead?
Was wondering if anyone has done this before and if there would be any downside to doing it. Was thinking of going to the hardware store and picking up a few extra gaskets/rubber washers for my bulkhead install. I painted the back of my aquarium and without a gasket on the outside (using the included gasket on the inside of the tank of course), I know that when tightening the nut that the paint will scrap up and flake off. I was thinking I could avoid this by simply adding another gasket on the outside...any opinions on this? Thanks in advance!

You can certainly double up if you want but it may actually cause more problems than it solves....
A properly secured bulkhead only requires one.. The gasket normally goes between the bulkhead flange and the glass on the inside of a tank.. You should not need one on the nut side (outside) thus your paint will not be an issue.. If it leaks thats because the internal gasket has already been penetrated by water... No amount of paint on the outside will cause that failure.. The nut should always be on the "dry" side (outside) Also.. remember.. Only hand tight plus 1/4-1/2 turn.. NO more.. Overtightening causes more failures

What is preventing you from getting a small artists paint brush and carefully repainting around the bulkhead if some gets scraped off?

The gasket on the nut side can interfere with proper tightening too..
If your paint was applied properly then there shouldn't be an issue.. Not to mention any paint removed by friction of the nut will be under the nut and not seen anyways.. and yes.. if needed touch it up after you put the bulkheads in place..

Using two can cause issues. ONLY use 1.
The trick here is to make sure you remove the casting seem on the plastic bulkhead. Had many leak before cleaning that up. use a little vegetable oil if you don't want scratches. If your OCD sand the nut with some 400 wet n dry |

You can also try these: http://www.coralvue.com/schedule-80-...d-slip-to-slip
They are excellent and use seated o-rings rather than flimsy washers. IMO/IME, quite a bit nicer than your standard bulkheads. The 1" ones also fit in the same size hole as the 1" Black sch40/abs ones.

Use a small dab of silicone grease (not silicone) on the outside under the nut and it will reduce friction between the nut and the paint.

You can over tighten it with or without a lubricant. The lube just allows the bulkhead to not rip off the paint.

Yeah, I just happened to stumble upon them a few years ago. I've used them on two different tanks now and they're pretty killer.
