I use two of the three Quick disconnects the water return quick disconnect was included when I purchased the CKSLWHAT-35-QD power/water return connector. One was used on the PP256’s Argon/air connector and the other QD was used with the W300’s Water supply, Blue QD female connector. As in another topic the Everlast Male Quick Disconnects did NOT come with a clamp.
