How long does a hydraulic hose last?

Most manufacturers recommend replacement every 4-6 years even if the hose looks fine — the reinforcement fatigues internally. In heavy-duty applications, inspect every 3 months and replace on visible cracking, kinking or seepage.

Can I mix hose brands and fittings?

Only if the manufacturer publishes a cross-compatibility chart. Otherwise you void the burst rating — a Parker fitting crimped onto a generic hose is not a rated assembly.
