I used this Pre-charged lineset in conjunction with another 50ft MRCOOL pre-charged lineset purchase at Home Depot. Couplers were purchased from Ingram's Water and Air as HD did not stock them. All were installed on a new MRCOOL 4/5 ton universal HVAC system.
After installation and lines were checked for leaks, we found the system was not fully charged. HVAC Tech had to add almost 3 pounds of R411 refrigerant. Rechecked all connections again to assure no leaks. System now runs great. I must assume that these lines are not fully charged as advertised.
