Can I Change Type of Dan Buoy Inflator?

No

When you need to purchase a recharge kit for your dan buoy, you may wonder whether it is possible to switch between recharge kit types. It is important to purchase the recharge kit which matches your dan buoy’s inflator.

A portion of the inflation mechanism is built in to your dan buoy. It is non–replaceable. It serves as the attachment point for the rest of the inflation mechanism. Please purchase the dan buoy inflation kit which matches the inflation mechanism on your dan buoy when you need to recharge.
