253-436-666 Viper Manifold Check Valve

253-436-666 Viper Manifold Check Valve for VR-4550/6000/7000/9000. Fits some older Mastercool and Snap-On Units as well. For Models VR-4500/VR-4550/VR-6000/VR-7000. Check Valve No. 2 and Check Valve No. 3 are located between the oil separator and the storage tank. Reverse leakage in these Check Valves can cause refrigerant to “flood” the oil separator, resulting in poor compressor performance.
