Bulkhead has 2 gaskets .. use both or just one?

[125mph]

I have 1.5" bulkheads for my overflow.. It came with two gaskets. I know I'm suppose to use one in the wetside.. I never seen bulkheads that come with two gaskets.. Do i skip the second gasket or use it on the dryside too, before the nut?

You don’t need to use one on the dry side nut, it’s just a spare. It will probably leak if you use 2 gasket.

Is it the same gasket? Some do come with two. One for the wetside one for the dry, but the one for the dry side is more of a ridgid plastic.

Some schedule 80 bulkheads come with 2 gaskets, but you only need to use one under the flange. Never had a schedule 40 come with two..

@ca1ore how are those reef octopus bulkheads treating you?

I have been extremely happy with them. Gradually replaced all of my sch 40 ABS bulkheads. You do have to put some molycote 111 on the o-rings and hand torque them down well.

@ca1ore did you find they run the same size for hole drilling as the abs ones?

 

[ca1ore]

Yes. They claim to be sch 80 but have the same dimensions as sch 40, so not sure how that works; but they are heavier and more robust feeling and made from PVC rather than ABS.

Thanks!
