Handle Position

Handles can be positioned essentially in 4 different positions - above each body port and at the back ("all open position"). One should choose the handle position according to purpose and sterilization needs.

Manifolds are available in 2, 3, 4 and 5 gang models.

Color Sequence

One should choose the color sequence of the handles according to purpose of use. The color sequence is defined by looking at the manifold when the female ports are pointed towards you. For example: the color sequence of the manifold in the picture is BWR (Blue-White-Red).

The right port can be female or male with luer lock nut.

Hight Pressure Stopcocks

The 3 way stopcocks are available in 2 configurations: "OFF" handle: handle arm indicating closed flow path. "ON" handle: handle arm indicating open flow path.

Perfectly designed to cover or seal the female ports of all our products. Protectors for female ports are available in 2 models: extended and recessed.


The protector's spigot extends beyond the thread, therefore the luer leads the protector easily to a female port upon assembly.


The protector's spigot is recessed in such a way that when the protector is placed on a tray with the luer downward, the spigot has no contact with the tray and therefore remains sterile.

The protectors are available in vented or non-vented (sealed) configurations. Vented protectors are used to enable ETO sterilization.

Male and female protectors assembled as one piece creating a spare part unit.
