Karl, You could use an expanding latex based foam. Dap makes it and you would use it just like the polyurethane foam. It stays soft and will allow for movement of the TQ tube relative to the body, I don’t see the polyurethane foam which cures hard doing that. Anyway, just my .02. good luck

Another person mentioned using the latex foam as it will stay soft, so i may give that a shot.
