Our Viair drain cock is made of high-quality durable corrosion resistant brass. It is an essential component for any system using a tank. It provides a quick, easy way to drain tanks, making maintenance a breeze. Draining water from tanks prevents settling and accumulation, which can lead to rust & deterioration. Frequent draining also helps remove debris that can interfere with your system. Keeping your tank and system clean of contaminants ensures longer lifetime and performance. Drain Cock is pre-treated with LOCTITE® 545™ Thread Sealant and is 1/4" NPT.
