"OLD" edwards fitting

Hi All

I am looking for the old type of vacuum fitting edwards used to put on
its pumps. It is an o-ring seal between a male and a female fittings
(1") and it is clamped with 2 C shaped clamps and 2 bolts (or 1 C
shaped clamp if connected to the mechanical pump).

Does anybody know under what name they are sold or even if they still
exist?

Thanks

Ozgur
