Specifications

General
Material	Stainless steel 304 as standard; 316 available on request

The connector body is machined from stainless steel and features a hexagonal section that allows tightening with a standard wrench. The push-in mechanism uses a collet and O-ring to secure the tube without tools, enabling quick assembly and disassembly. The threaded end connects to a female port, and the straight configuration provides a direct in-line connection. Typical uses include air lines, water circuits, and control panels where reliable, releasable connections are needed.
