Compatible with most refrigerants and lubricants, it improves system efficiency by eliminating moisture and reducing compressor stress, all while being safer and more eco-conscious than traditional seal treatments. ## Description RED TEK ProSeal is a formulated system designed to seal leaks in both metal and rubber parts of air conditioning and refrigeration systems. ProSeal is chemically activated by moisture at the leak site to form a permanent seal. ProSeal offers several benefits other than self-sealing properties. Moisture is chemically eliminated from the system. Removing moisture reduces compressor head pressure and enhances refrigerant flow which results in lower vent temperatures. RED TEK Pure Zero Patent Pending Technology is a natural, high-efficiency ultra-refined HC gas specifically formulated for use in refrigeration and air conditioning systems. Pure Zero is a Refrigerant Grade Gas made from UL Certified HC gases. Its ultra-refined technology greatly increases efficiency, performance, and reliability. RED TEK PureZero is designed to extend compressor life compared to other lesser refined HC gases that contain impurities not designed for use in air conditioning and refrigeration systems. Some of the largest manufacturers of refrigeration systems have made the switch to RED TEK PUREZERO!
