What is the leakage amount of KQ2 series One-touch fittings and KF series insert fittings?

There are no specific numerical values available. However, the fittings are in compliance with the following JIS standards:
For the KQ2 series: B8381-1
For the KF series: B8381-2
“No leakage occurs within 1 minute when the fitting fixed to a tube is underwater while pressurized for 5 minutes at both the max. operating pressure and 0.1 MPa.”
Note) As the leakage amount is not zero, be careful when using a leak tester, etc.
