This is a weird thread. It makes no sense unless the o/p is trying to make a point about something he's not saying.
Hose can be bought from any supplier. As already stated, use a different name etc, to order, and there's plenty of info been posted in the recent past on the topic.
Why would Gardiner's not sell something to a competitor knowing that if that competitor was serious, they'd order it via someone else and how did Gardiner's know the o/p was a competitor?
And who is Diamond Standard Ltd?
Weird.
