1/4" MNPT Air Compressor Tank Drain Valve Male Easy Twist Petcock

1/4" NPT Air Compressor Tank Drain Valve Petcock

This reliable air compressor tank drain valve, also known as a petcock, is equipped with 1/4" male NPT pipe threads—the standard size for most air compressor tank drain ports. The 1/4" NPT threads measure approximately 1/2" in diameter. Unlike traditional T-handle style petcock drain valves, which rely on brass-to-brass seals prone to clogging from debris, this valve uses a rubber seat seal for a tight, dependable seal, ensuring smooth operation and preventing leaks. Made from durable solid brass, it is built to withstand long-term use and is also corrosion resistant. When fully open, the valve extends 1.3" in total length, once installed the remaining protruding part will measure around 0.9" for clearance reference.
