stainless steel quick connect, 1/2 inch, male plug, female thread
This stainless steel quick connect, 1/2 inch, male plug, female thread is the perfect way to switch your airlines from glad hands. It is a partner to the female plug end with male thread, MCSHC83. The female end threads into the existing bulkhead in your airbox, and the male end threads onto your trailer airlines. Stainless quick couplers use all the existing parts you have but add a clean professional look to your rig. They also make hooking and unhooking so much easier and thus more efficient.
To ensure that your airlines cannot be accidentally crossed, use the quick connects, MCSHC86, and MCSHC31, to differentiate between your emergency and service. This set is reversed from the standard and so the male end threads into your airbox bulkhead and the female end threads onto the trailer airline. Using one set like this and one standard set, keeps your airlines at the right place.
