is it normal for a quick disconnect set?



Hello! This is my very first post in here. I'm just wondering, is it normal for a Genuine Iwata quick disconnect set to leak air when I move my airhose at an angle or when I poke where the male and female connector meet?
I bought it from Amazon as I have prime for one day delivery and no hassle if returning an item. Here is the link:

do I have a defective item? Help would be much appreciated! Thanks.
Someone else had brought this up earlier today ,
I always suggest using something like WD40 to lube them when you first get them, Some have rubber o-rings inside some have teflon but both need lubed.
Try that first and if it still is causing you issues then just return them I have never had a problem with my Iwata quick connects
