Not exactly the same kind of hose clamp are they? The clamps supplied on all these drain couplings are stainless steel... Unless you are buying chinese ones then they might be made of just about any material.
I've got 2 of them... of course, I once had a dive knife that had "Stainless" stamped on the blade. It was easy to read, 'cause the letters were all rusted.I have never seen a stainless dryer vent hose clamp...they all are steel.
Stainless steel comes in many grades
Good clamps usually say "All Stainless" on them.
Here is what I found in the 2009 IPC:Here's another Code question about the use of Fernco flexible couplings:
Section 6.05.6 of the International Plumbing Code says, "Access shall be provided to all flexible water connectors." Does that section apply only to flexible connectors used in water supply plumbing (chapter 6 of the Code)? Or does the word "all" mean it also applies to flexible connectors used in sanitary drains (chapter 7)?
Consider the ledges that would be in threaded galvanized fittings and leaded cast iron joints.A related concern is that the coupling provides a ledge that may make clogs more likely.
