4-Pack 304 Stainless Steel 1/2-28 to 3/4-16 Thread Adapter This 4-piece adapter set is crafted from premium 304 stainless steel, offering outstanding strength, heat resistance, and corrosion protection. A significant upgrade from common aluminum adapters, these are built for long-term performance in mechanical and industrial environments.

O-ring for the 1/2-28 female side
Every adapter in the pack includes its own washer and O-ring, providing improved sealing, vibration reduction, and protection against metal-to-metal wear.
Made from stainless steel, these adapters offer superior longevity, high-temperature stability, and excellent resistance to thread damage—ideal for repeated installations and demanding usage.
Perfect for equipment setup, workshop projects, hobby customization, metalworking tasks, laboratory rigs, and general mechanical thread conversion needs.
