This is a pneumatic fitting pipe connector designed to join tubes in air systems and is also suitable for water applications. It uses a push-in design for easy, tool-free installation and removal of hoses. Key benefits - Fast, tool-free connections and disconnections save time during setup and maintenance. - Reliable fastening to keep hoses securely in place in both pneumatic and water system applications. - Focused 10 mm PU version provides a robust solution where 10 mm tubing is used. Key attributes - Size options: available in 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, and 14 mm. This listing focuses on the 10 mm size with PU material. - Material: PU (polyurethane) for the 10 mm version. - Function: push-in design enables quick hose insertion and release. - Compatibility: suitable for tubes used in air systems and for water applications. - Models/series: product code includes HVFF, PK, PV, which may refer to different models or series. Use scenarios - Pneumatic automation: connect and quickly remove hoses between a compressor and actuated cylinders on a production line to minimize downtime during maintenance or changes in tooling. - Water cooling or coolant circuits: set up temporary or semi-permanent connections in small cooling loops or filtration systems for easy assembly and modification. - DIY and prototyping: create and modify air or water circulation setups for experiments, demonstrations, or hobby projects with straightforward push-in connections. How to use - Insert the tubing into the connector until it seats firmly. - To disconnect, pull the hose gently to release the grip and remove. Care and maintenance - Inspect the connection regularly for wear or damage. - Replace the connector if the PU material shows signs of wear or loss of grip to maintain a reliable seal.
