HVAC techs and DIYers, keep your service ports sealed and protected with this 10-pack of solid brass valve caps. They're designed for 1/4\ flare connections with 7/16-20 UNF threads (common on AC service valves). Each cap has a high-quality neoprene O-ring inside that creates a leak-proof, dust-proof seal to keep refrigerant in and contaminants out. Made from corrosion-resistant brass, they're durable and can handle various environments. Just screw them on by hand – the knurled edge makes it easy to tighten and remove without tools. Essential for sealing off ports after service on home AC units, refrigeration systems, or in industrial applications. They help prevent accidental depressurization and keep your system running efficiently. A simple, affordable part that's crucial for proper maintenance. Don't leave those valves exposed – cap 'em!
