I was wondering what are the dimensions of this product, and additionally, what is the piping connection dimension (sizing of piping to connect to the valve)

Hello dwarwick.42over9000 and welcome to the Digikey TechForum.

According to this blog post from Olimex it appears that it has a 6mm sleeve for connection.
From what I could find online, it appears that this is using a PURO-XD-12 pump, based on what I could find for that, the dimensions provided are: Item dimensions 2.44L x 1.38W x 2.36H inches.
