WARNING
Never connect a low pressure hose to a high pressure port. These connection
threads are different sizes and are not compatible. Do not use adapters of any
kind to connect low-pressure devices to high-pressure ports. Doing so could cause
serious damage to both the user and equipment.
!
WARNING
Do not attach a L.P. hose to a Scuba regulator high pressure (HP) port or to an air
supply with pressure in excess of 200 psi (13.8 bar). This may result in damage or
explosive failure of the Ination Valve or Low pressure Hose, which could result in
injury or death.
