The Brass Quick-Connect Coupler is designed for heavy-duty use while remaining easy to operate. Its ball-lock mechanism provides a secure connection that prevents leaks and accidental disconnection, while the knurled sleeve allows quick insertion and release of the male plug for fast tool changes.
Standard 3/8″ air couplers are typically rated around 500 PSI, while industrial brass or steel fittings used in pneumatic systems can handle approximately 35 bar (≈ 500 PSI). Reinforced versions designed for high-pressure or hydraulic applications may support several thousand PSI depending on material and class, and this coupler is suitable for pressures in the range of 3,000 to 5,000 PSI, making it compatible with commercial gas or electric pressure washers.
Precision-machined threads and high-quality O-ring seals ensure reliable, leak-free performance, with a maximum operating temperature of approximately 212°F (100°C). The solid brass construction provides durability, corrosion resistance, and long service life in workshop and industrial environments.
