Product review (3 stars): Good enough for on-demand water heater flush (definitely not for washer lines)
I would never use rubber hoses for the constant pressure they would experience hooked up to a clothes washer, but these worked fairly well for hooking up to a pump to flush my Rinnai on-demand water heater. The "brass" color washed off the connectors from the vinegar flushing solution, makes me suspicious of the longevity of these hoses in this non-standard use.
