Welsh Premiership rivals Aberavon, Newport and Pontypridd also recorded comprehensive victories to ease into the fifth round.
But Pontypool were given a scare at Bonymaen before pulling through 13-5. Pooler went behind on ten minutes through a try from winger Robert Jones before first-half replies from Will Kershaw-Naylor and Calwyn Morgan gave the visitors a narrow 13-5 victory.
There was a dramatic finish in Llanelli, as Felinfoel led Caerphilly deep into injury-time. With the score tied at 31-31, having scored five tries to Caerphilly's four, the Carmarthenshire club looked to be heading through on the try count rule.
But Felinfoel lost their lineout with seconds remaining and outside-half Danny Ellis touched down under the posts to clinch victory for the visitors.
There was just time left for Ellis, a second-half supersub, to kick the conversion before the referee blew up to allow Caerphilly to go through 38-31.
