Could work better
First off, I don't know why anyone would order these adapters from any place other than Intex directly - the manufacturer. They sell them for about $2.50ea and you can get two, delivered anywhere for about $10.

Second, while they do attach nicely, they do cause the rest of the hose and attachments to stick out and pull down on the protruding 1 1/4" black nozzle as another poster indicated.

Finally, there is a design flaw in that the black gasket, on the end of the adapter that attaches to the plunger valve, is mated to a rim that is hollow. You can see this by just pulling the gasket back on that edge. Once assembled everything will work fine for a while. But after a few minutes, the gasket gets sucked into the hollow rim and causes air to enter the system resulting in a "buzzing" around the adapter and significantly reduced water flow - probably not good for the pump either. The rim really should be a solid flat surface for the gasket to mate to. This is probably caused by the a pump that is designed for 1 1/2" openings moving water through the a 1 1/4" adapter.

I considered fixing this by filling the hollow edge with liquid resin available from a craft store. I ultimately just cut out the 1 1/4" inflow and outflow black tube and installed the strainer/nozzle assemblies that came with the pump, ditching the adapters altogether. Everything works fine and I have an 1 1/2" path through the whole system. An added benefit is that the assemblies now don't pull down on the pool liner as they are closer and have much more surface area in contact with the liner.

Order canceled!!!
I ordered this item as I had plans to upgrade my pump and upgrade to a saltwater system. My Kids were anxiously awaiting the use of the pool for the summer. I ordered the filter pump from another company on Amazon because it was cheaper. CMS then CANCELED my order because I did not order the pump from THEM!!!! With todays economy this is deplorable!!! To punish a family who is trying to save a bit on shipping and order a product from someone who is offering it cheaper than your company!!! I have never been so disgusted!! Amazon shouldn't even allow your company to sale on their site!!!

conversion adapter
When we bought the pool from Sam's we should of upgraded the pump
from the beginning
We used this conversion kit and I ordered a stronger pump
I strongly recommend you up grade the pump
We built our own ladder
We love our pool
The conversion adap was easy

Works well
These hose adapters go on very easily and seal up perfectly, the only problem I really have is that they are a bit heavy. I have the 16ft easy set pool and these are heavy enough to the point that they pull down on the pools hose attachmants, I was a little consered that with that weight like that they may eventially slip off and produce a leak but they havent they have held up great.
