FKFKQ2H Series Straight-Connection Joint
Detailed description
The FKQ2H Series straight-connection joint is designed for efficient and reliable pneumatic connections, combining ease of use with robust performance. It supports quick insertion and removal through a one-button mechanism, allowing for smooth operation with minimal force and no risk of damaging the tubing. The release sleeve is available in both round and oval shapes to suit different application preferences.
As a differential straight connector, this series is specifically engineered to connect air tubes with varying outer diameters. It offers broad compatibility across metric and imperial tube sizes, making it suitable for diverse installation requirements. The sealing structure ensures dependable performance across a wide pressure range, from -100kPa vacuum up to 1.0MPa (10 bar), accommodating both vacuum and pressure applications.
The joint features a compact and lightweight construction, with a PBT body and brass threads.
Its small size and low weight make it well suited for installation in confined or space-limited environments. Material compatibility includes nylon and PU tubing, with NBR seals providing stable performance within an operating temperature range of -5°C to 60°C. When used with water media, the recommended temperature range is 0°C to 40°C.
