The APC series with a nominal inner diameter of 7,9mm has a plastic release button, a small amount of moving parts and a design with smooth contours. It is therefore easy to operate and ensures excellent flow rates at compact dimensions. The APC series was expanded by coupling versions with valves and protective collar at the release buttons. To expand the field of application some version were designed to be even more robust.

For tubing with an inner diameter of 7,9mm

Very low flow resistance due to 7,9mm nominal diameter. Not completely leak-proof (meaning that after separation 1-2 drops may spill)
