I got both a pin lock gas and liquid disconnect with some other stuff I picked up. They have the 1/4' MFL connection. I only use ball lock so have no use for them.
In the spirit of pay-it-forward, I'll send them to the first person to respond to this thread. I'll pay postage (Continental US). If your post is first, send me a PM with your address and they will be on there way.
Thanks to HBT!
