specialty bulkhead

[darren_sfsu]

Hello,

I need an unusual sized bulkhead for a low-flow application:

I have an insulated fiberglass tank that is 3 inches thick, so I need a bulkhead with a length of greater than 3 inches, preferably 4 to ensure enough threads exposed.

any suggestions on a vendor that stocks this dimension (vs a custom)?

I have fabricated with PVC a DIY bulkhead, that has worked well, but I am doubtful of its longevity, particularly the gasket.

here are some random picks of my set-up: 1800 chilled seawater system!
