    I need to install a new flange on a lead pipe. The pipe has an immediate elbow under the floor so I cannot use the flange with a neophren gasket designed for this purpose, since its extra length would partially block the pipe. It appears my only choice is to use a standard, shorter plastic flange with some kind of sealant between the flange and pipe rim. Any suggestions about the best type of sealant for this? Silicon? Plumbers putty?

    Or is there a better solution?

    The only real way to do what you want to do is get a brass flange and solder it to the lead pipe and screw the brass flange to the floor...

    Just because some manufacturer makes claims doesn't mean that it any good. The easy way isn't always the best way.......

    Plastic flanges are for plastic pipe. For a lead bend you need a brass flange soldered to the lead.
