Gas ball lock disconnects (Grey). You have a choice of a 1/4" barb fitting or a 1/4" MFL fitting. The MFL is nice for quick changing lines or adding other equipment without cutting your lines. If you order the MFL disconnects, be sure to order the 1/4" or 3/8" female hose nipple with it!

The babred fitting will be sent by default if no option is picked.
