A very well designed manifold and a trusted name in HVAC. Large, easy-to-see pressure gauges and well-convoluted hoses with easy-to-use ball valves. I love that you can repair/replace the seals. I bought this instead of a cheaper model because I find the aluminum header case helps drain and expand the liquid coolant faster. I wish this distributor had the old big valve knobs for easier turning with gloves on.
