SHORT LIFE EXPECTANCY ON “LEAK PROOF” SERVICE HOSES
The new environmentally safe, leak proof, service hoses may have a shorter life span than previous “non-leak proof” hoses. Use of check valves or shut off valves on the hoses subject the “leak proof” hoses to extremely high pressures when they are not in use.

Previously, hoses did not have shutoffs to contain the refrigerant when the hoses were disconnected from the system. The pressures in the hose were relieved during periods of non-use.
The new hoses capture pressures that can build to extremes while they are not in use. The use of check valves and shutoff valves on hoses warrants extreme care when using.
Think about disconnecting a non-bleed hose from a high side connection on a unit. The pressure may be 250 lbs. at the surrounding temperature of 85˚. The check valve/shutoff doesn’t allow the pressure to dissipate.
Now put the hoses and manifold into a truck which is 100˚. What incredible pressure do you think will develop in the hose?
The continued high pressure exposure is the reason for the shortened usable life expectancy of the hoses.
