there is a male to male straight through connector, but for what it's worth, go buy the right length of tigerflex to replace the entire run between filter and return - less likelyhood of leaks etc. with less connections along the way.
I guess I'm off to the pool store later. I'll certainly look into just swapping the hose out for the proper size, but probably not til the fall now, since we only just got the water level up, etc. If I can get those two useless attachments off for now I'll be happy.
