C-Type Self-Locking Connector User Guide

Product Introduction
The WENK Pneumatic C-Type Self-Locking Connector is a high-performance pneumatic fitting designed for quick and secure connections in industrial applications. Its innovative self-locking mechanism ensures reliable attachment without accidental disconnection, even under high pressure or vibration.
Constructed from durable materials with corrosion-resistant plating, this connector offers excellent sealing performance and long service life. Its user-friendly design allows for tool-free operation, significantly improving workflow efficiency in manufacturing, automotive, and construction environments.

Installation Steps
-
Preparation
- Ensure the air supply is turned off and the pipeline is depressurized
- Clean the connector surfaces, ensuring no dust, oil, or debris
- Check that the O-ring is intact and undamaged
-
Hose Connection
- Select the appropriate C-type connector based on the hose size
- Insert the hose into the hose end of the connector, ensuring it is fully seated
- Gently pull the hose to confirm a secure connection
-
System Connection
- Align the male and female connectors along the same axis
- Push the male connector into the female connector with moderate force until a clear "click" is heard from the locking mechanism
- Gently pull both ends of the connector to confirm a secure lock
