One hose is red and connected at both ends by a jubilee clip. It is perished and leaking at the cylinder end. The other hose is black and has a different type of connection at each end, via a kind of nozzle held onto the hose by a metal collar, and connected to the cylinder and valve by brass hex nuts.
I inherited this set-up. Obviously I need to change the red hose. Anyone know how to specify what I should order? Is it easy to fit these things yourself?
