Hi Colin,
It's Gwent hydraulic hoses, based in Newport gwent. I was using an Extracta Excel, and the hose sprang a leak in the customers house. I used these people who supplied me with 2 lengthe of 7.5 metres with the ends crimped on. The hose is black in colour, and is non marking.
Funny though it is, if i used Craftex powder, the crimps used to pop off, so i started crimping them back on using a banding tool known as Ligarex which is strong enough to hold them on. There must be something in this powder to allow this to happen.
Also they supply the suction hose, but i dont know the price. Incidentally, get hold of a Craftex catalogue as i think they may sell the cuffs. Apart from this, there was a cleaning magazine that was sent to me with a reply card for enquiries, and i used to get the catalogues from the suppliers, such as water pumps etc.
