Precautions

Selection

Applicable fluids

  • *Corrosive gas: Do not use corrosive gas as it may cause corrosive stress cracks and other problems.

Piping

Wrapping the sealing tape (when R screw is installed)

Wrapping the sealing tape (when R screw is installed)

Wrapping the Sealing Tape

  • *Sealing tape is not required as this product uses a pneumatic and hydraulic purpose G thread which conforms to ISO 1179-1.
  • *When an R (taper) thread is used, leave 1 to 2 threads exposed at the tip before winding the sealing thread around it 4 to 5 times.

Always tighten threads with the proper tightening torque

*When attaching fittings to valves, tighten with the proper tightening torque shown below.

  • Connection threads (G, Rc 3/4): Proper tightening torque 28 to 30 N·m
  • Connection threads (G, Rc 1): Proper tightening torque 36 to 38 N·m

Operating environment

  • *Do not use in locations with an explosive atmosphere.
  • *Implement suitable protective measures in locations exposed to water, oil or spatter from soldering, etc.

Maintenance and inspection

Storage

  • *In the case of long term storage after use, first thoroughly remove all moisture to prevent rust and deterioration of rubber materials.
