Washing Machine Inlet Hose Extension: Proper Connection Techniques for Leak Prevention

Due to the dishwasher's distant location from the water source, I bought an extension hose, which I installed in the faucet, and connected the end of the hose with a special plastic connector (threaded on both sides) to the dishwasher's aquastop hose.

My problem is the connection of the plastic connector to the extension hose (the one from the battery). The hose was fitted with a blue gasket. The first time I connected the connector with the hose "sensitively" - the connection is leaking, tightened it - the connection is leaking. I added a second additional gasket. I tightened "sensitively" - it is leaking, I tightened it forcibly - it does not leak. After three weeks at night, there was such a leak that I flooded the neighbors. Further tightening does nothing. Please explain to me how to connect a plastic connector with an ordinary hose so that it does not leak? One gasket, maybe two, tight, sensitively, or maybe some strings, or pour silicone?

I use metal nipples to connect two hoses.

As already written - connect the plastic connector to the bucket and buy a decent metal one. See if the gaskets and mating surfaces are OK, without pitting or cracks. Leaks between the extension and the connector or on the other side at the dishwasher hose?

PS. By the way, the sense of buying a dishwasher with aquastop is strange and then doing such inventions and flooding your neighbors. Maybe it's better to take a man to just extend the installation with a piece of copper (even on top of the handles, if it's behind the furniture and you can't see it).

Exactly between the extension (purchased hose) and the connector (plastic nipple). The connection of the connector (plastic nipple) - the dishwasher is approx.

I live in a dorm temporarily (the dishwasher is in a different room than the access to water). I bought a dishwasher with my own apartment in mind, hence the aquastop .

How about a quick garden cable connector?

It changes things. If the tap is not very far away, you could simply use a second ordinary hose such as a washing machine or dishwasher that you can buy at the store.
