They have good threads. The 2-stage seal can be felt, the retaining flange has an elongated shape, which makes it easy to loosen and separate the fitting from the hose if necessary. I use them for both air and water at over 100psi with no problems, they are a bit larger than I expected but they should be very good quality.
