From what I remember...nurse....the hose should be date stamped in such a way that it is disposed of after a number of years. It used to be 3 digit letter code by most manufacturers, or I could be dreaming it again. We have gone for replacing hoses after 3-5 years and found it was as cheap as getting any checked. We just need to make the odd 12.76 meter MA7 hose up every now and then in an emergency..usually someones fridge compressor or tyres need blowing up or mri scanner room
