Swagelok SSQCA31400K4 Quick Connect Fitting One Quarter Inch

The Swagelok SSQCA31400K4 Quick Connect Fitting is a 1/4-inch, 316 stainless steel instrumentation quick-connect coupling (QC Series) designed for fast, leak-tight connections in fluid-handling and instrumentation systems without tools. It uses a fluorocarbon (FKM) O-ring and a Swagelok tube-fitting connection, with Dow Corning 111 lubricant, and supports up to 3000 PSIG at 70°F (250 PSIG at 400°F), a maximum operating temperature of 400°F, a minimum of -65°F, and a flow coefficient (Cv) of 0.2. The 316 stainless steel body and FKM seal are suited for industrial fluid and gas handling environments and installation is via a tube-fitting connection. Common media include air, gas, hydraulic fluid, water, and compatible chemicals. Typical applications span gas sampling systems, analytical instrumentation, semiconductor manufacturing equipment, chemical processing, laboratory systems, and hydraulic test stands where rapid line changes and minimal leakage during disconnection are crucial, and it complies with Swagelok SC-10 Cleaning and Packaging Standard.
