Product review (5 stars): Not overpriced when compared to cost of a flood.
I had to replace mine, this small piece of simple looking plastic is similar to a "T" used in aquarium plumbing... but 10 times the price. I decided I could use some kind of fastener to hold it in place, like a Red Green fix. Long story short, didn't work and the hose shifted slightly over a matter of hours causing a leak and a puddle to form around the back half of the furnace.

My advice, it's not overpriced compared to having water damage from trying to jury rig a cheap fix.
