※. These values may differ for some products. Refer to each specification as well.
④. When removing a fitting, use proper tools to loosen a hexagonal-column
or an inner hexagonal socket. When inserting a hex key into the inner
hexagonal socket of the fitting, be careful so that the tool does not
touch lock-claws. The deformation of lock-claws may result in a poor
performance of systems or an escape of the tube.
⑤. Remove the sealant stuck on the mating equipment. The remained
sealant may get into the peripheral equipment and cause malfunctions.
10. Handling of fitting
①. Impact caused by dropping or the like may lead to damage to the
product and a fluid leakage.
