I believe it's the same hose as the one on the sink, when it comes to the plumbing hose, they're made hard for some reason but air hoses are soft, I think the ones on the spray guns on the sink are the same as the air hose because they dont require much pressure, as for the sleeve creeping up, I only had that problem when my hose was stiff, When it was stiff it kept a curve that it was given during packaging so it just slid up the hose. if that makes any sense
