The hosts, who are now in third with a week to go, had a truly special performance by full-back David Gratton to help them to a seven-try, 46-13 triumph.
Gratton scored four tries and added seven points with the boot, while there were also scores by Dean Scarf (2) and Kyle Perry to see Rhydyfelin home.
Newport HSOB are now safe in Division Three East after a fine 13-3 victory at home to Rhymney. Captain Will Lowe scored the only try of the game late on and full-back Will Edwards added eight points with the boot as Newport secured another season in the division.
