Cor15 Fittings Question

[f8thless]

Hey guys - I'm trying to redo the plumbing for my cor15 pump.

I'm trying to hard plumb 3/4" pvc and need a new fitting that connects to the pump.

My question is, is this the part (reducing bushing pvc) I need and if so what size? Also I assume I'll need an o-ring? If so, then what size for that?

Thanks in advance!

The COR 15 pump comes with a union that has a US slip fitting on one side and a BSP threaded fitting on the other side. It’s a very unusual fitting and you probably need to contact Neptune to get a replacement. It is unlikely that the part you linked to will fit and seal correctly.

Ah gotcha. Thanks for clarifying!

You will need this

and then you will also need what you linked in a 1 1/4" to 3/4" size.
