Handling Instructions and Precautions
●
Usable tubes
Use of both nylon tubing and urethane tubing are supported.
Nylon tubing outside diameter precision should be within
±
0.1
mm [
±
0.004 in] (nominal) for nylon tubing and within
±
0.15
mm [
±
0.006 in] (nominal) for urethane tubing. Use tubing with
ovality (difference between major axis and minor axis) within 0.2
mm [0.008 in] (use of Koganei tubing is recommended).
Use of tubing that is not a Koganei genuine product or a
compatible (recommended) product may result in tube
disconnection, air leakage, or other problems. Be sure to check
on tubing before building a pneumatic system.

NOTE
1. Use tubing with an exterior that is not damaged. If tubing
becomes damaged after repeated use, cut off the
damaged portion.
2. Do not allow tubing to become severely bent or twisted
near the connection to a fitting. Such a condition creates
the risk of air leakage. The table below shows minimum
radius guidelines for nylon and urethane tubing.
3. Do not use extremely soft tubing, which causes a severe
drop in pull-out strength.
4. Before removing any tubes, always turn off the air supply.
Also, be sure to confirm that the air inside the pipes is
completely vented before starting.
