I use these check valves in a petroleum system at 140 degrees. F 24/7 for 16 months without problems. It was time to replace the motors and tubes, as well as scheduled maintenance, and they still worked perfectly. When I removed the hardened hose from one of these, the valve cracked, but that's to be expected as mineral oil makes the plastic brittle over time. In short: they have performed excellently in harsh conditions for a long time.
