TL;DR
Hose burst rating is the pressure at which a pressure-washer hose is designed to rupture, set by safety factors at three to four times the working pressure printed on the jacket, so a 4,000-PSI working hose may carry a 12,000-PSI burst figure. Buyers compare working pressure to their machine's output and reserve the burst number as the safety margin that absorbs spikes from trigger-gun closure.
What it means
Hose burst rating is the pressure at which a pressure-washer hose is designed to rupture, set by safety factors at three to four times the working pressure printed on the jacket, so a 4,000-PSI working hose may carry a 12,000-PSI burst figure. Buyers compare working pressure to their machine's output and reserve the burst number as the safety margin that absorbs spikes from trigger-gun closure. Abrasion, kinks, and sun-rotted jackets erode that margin, which is why pros retire hoses showing exposed braid rather than risk an injection injury.
