I have tried my local hydraulic hose place,to see if they could supply the hose,stuff on my prochem machine is non marking,as i am sure most of the other machines use,place said they couldn`t find a supplier !
BNut after reading this it wouldn`t need to be non marking ,say if you had 50 odd foot for inside the property,will go back and see them again,they do the fittings as they have done repairs for me in the past
