Plumbing Question (Filter Roller)

[aja1216]

I finally got my Marine X 90.3 (first tank) and I'm using a Clarisea filter roller that I would like to hard plumb. I'm going to need 2 - 90 Elbow and some additional straight pipe. Waterbox uses metric so I have to order them. My question is do I use the ID or OD when ordering?

Thanks!

PVC pip is measured by the inside diameter ID.

Depends if you are asking about the metric sizes or standard.

Metric uses the OD of the pipe
Standard sizes uses standard schedule pipe sizes. The OD will be the same but the ID will vary will schedule size.
