Having the right stuff in your save-a-dive kit can make the difference between a great dive and the worst day of diving you ever had. Watching everyone else swimming out from the beach or making a giant stride entry off the back of the boat and you're just sitting there with a bad inflator mechanism is something that can be prevented if you come prepared. Always carrying spares of the easily replaceable parts can make this nightmare never happening to you.

If you have a Sea Quest Air Source or a Zeagle Octo+ or an Oceanic Air XS, AerisAir link this is a must spare for your kit. Just a couple of wrenches and presto! You have replaced a vital coupling and can still make the dive the connector will work with any standard regulator second-stage hose. Coupling is manufactured from Marine Grade Chromed Brass for long life and durability.
