Intex makes at least a couple different hose fittings, some close to standard with hose clamps and some that use O-rings and collar nuts. I don't know that any of them are in standard sizes. You'll need to take a good look at your fittings on the pool, the hoses, and standard fittings and figure it out from there. One clue: standard hoses and fittings are sized by the inside diameter of the hose, so if your Intex hose is 1-1/4" on the inside, you may be able to use a 1-1/4" hose barb with it.
