The "Octo-Z hose to Generic Inflator Hose Adaptor" allows a standard power inflator to be used with an Octo-Z hose. This quick disconnect hose adaptor plugs into a Zeagle Octo-Z hose and allows the Bx power inflator and most other generic inflators to be use with the Octo-Z hose. The advantage to this is being able to quickly change between units without fiddling around with replacing hoses.
