Description

Quick Connector GW 3/8-Inch Female Thread, Brass

Brief Overview

This brass quick connector is engineered for reliable, fast-connect pneumatic and fluid line applications in professional shop and industrial environments. The 3/8-inch GW female thread design pairs seamlessly with corresponding male-threaded hose adapters, making it an essential component for building modular compressed air systems. Whether you're assembling workshop air lines or fluid transfer systems, this coupling delivers consistent performance. Consider pairing this with complementary larger-diameter brass quick couplers or smaller 1/4-inch connectors to build a complete line of quick-connect options for your resale catalog.
