Bob,

I just don't
understand the design of the gates and how they're intended to be
incorporated in a DC system. Even if one used just WW parts and hoses
(never mind the PVC pipe), I can't understand why blast gates would have
tapered connections on both ends.

Yeah, they are a pain to connect to anything.

I cut 8 slits in the S&D PVC pipe and then clamped it to the metal blast
gate using a flat stainless hose clamp. It holds it very rigidly because the
metal gate is a solid casting. I don't know how well this would work with
the plastic gates.
