Can JFC Retail be used to repair a leak or hole in copper pipe or brass fittings?
A. NO! JFC Retail cannot be used to repair leaks or holes. If there is a leak in the connector or fitting, the fitting should be removed, properly prepared, then bonded with JFC Retail. If there is a hole in the copper pipe, the section with the hole should be cut away and replaced. The other option is to use JUST-FOR-COPPER AMINE EPOXY PUTTY to make the repair.
