Push-in fittings are designed for connection of pneumatic hose (with calibrated external diameter). The connection in achieved by pushing the hose into the fitting. To disconnect, the releasing collet must be pressed down. The most suitable hose material for push-in fittings is polyamide. Series R push-in fittings and series Fox miniature fittings are the best elements for connecting pipes and actuators in pneumatic systems. Quick and easy to use, the push-in fittings can be re-used thousands of times without affecting the pneumatic and mechanical seal in any way. Coming in various configurations and guaranteeing a virtually unlimited, highly flexible use. The clamping spring of special shape grips the pipe without scratching or deforming it, which facilitates release.
