## Product Summary

PC-C pneumatic fittings are mini male straight push-to-connect connectors designed for compact tube-to-thread connections in pneumatic systems.

With a straight structure and mini compact design, PC-C fittings are ideal for installations where space is limited, such as small valves, mini cylinders, and precision pneumatic equipment.

The fitting uses nickel-plated brass construction combined with an O-ring sealing system, providing corrosion resistance, reliable sealing, and long-term durability.

Push-to-connect technology enables fast installation and easy tube removal without tools, improving efficiency in compact pneumatic assemblies.

OEM and ODM customization services are available for tube size, thread type, and branding requirements.
