where to buy 40 mm pipe and fittings

[Isomorphic85]

I have a redsea Max S 650 and the main pipe from the weir to the sump is 40 mm. I want to try and plumb in a roller mat to the sump return , the roller mat also accepts 40 mm in the bulk head. Where the heck can I buy 40 mm pipe, fittings, unions etc in the united states?

I would just purchase a couple adapters and use imperial sized pipe. Really broadens your options when it comes to the pipe itself.

as a side note this company DOES sell 40mm pvc pipe but it is only available in the dark grey and I don't think they have fittings for it.
