Flow Control Equipment Air 0.1 MPa .5 to 60°C (No freezing) Antistatic soft nylon tubing (Series TAS) Antistatic polyurethane tubing (Series TAU) 104 to 107 Ω Seal: Conductive NBR Seal: Conductive NBR Body: Conductive PBT Body: Conductive PBT UNI thread It is possible to prevent products from being electro-statically charged by applying conductive materials (using conductive NBR seal) and grounding UNI thread structure.1) (Gasket seal method). .1 Ensure that the female thread connected to the speed controller is grounded. If not grounded, there is a possibility that the controller and tube may remain charged. Antistatic tubes should also be used.

(With taper threaded screws it is necessary to apply a sealant to the thread, which electrically insulates the controller causing it to become charged.)
