Metal Push-In Fittings – MP Series
The Brass Push-In fittings from the POOLKE MP Series are designed for fast, reliable tube connections in pneumatic and fluid systems. The push-in structure allows tubing to be inserted directly without special tools, while the release ring enables quick disconnection for maintenance or piping changes. This simple connection method helps reduce installation time and makes the fittings well suited for automation equipment, compressed-air circuits and industrial machinery.
The MP Series uses a nickel-plated brass body and gripping components to provide good mechanical strength and corrosion resistance. A full-flow internal design helps maintain efficient media transfer, while multiple straight, elbow, tee, Y, bulkhead, swivel and union configurations provide flexibility for complex piping layouts. Tube sizes are available from 4 to 14 mm, together with inch options. With reusable tube connections and a wide range of thread standards, the Brass Push-In fittings provide a practical solution for industrial pneumatic installations requiring compact size, easy assembly and dependable long-term performance.
