Correct, the gasket is different.
A 2gn PVC valve could be made to work, as I have mine plumbed like a 1gn/old school routing, but with the 2gn valve. For the 1gn VC, you would just need a 3/8 pipe to 3/8 barb adapter, some 3/8 vacuum hose, and clamps.
Something like this, except with a barb, instead of the compression as shown, unless you want to run metal/hard plastic tube to a catch can.
