3.1 MP Inflator Hose Installation

WARNING: DO NOT attach the medium pressure (MP) inflator
hose to a high pressure (HP) port (greater than 200 psi). This may
cause the hose to burst when pressurized, which can result in
serious injury.
Most first stage regulators contain medium pressure (MP) ports that are smaller
than the high pressure (HP) ports - 3/8" MP ports vs. 7/16" HP ports. Some
older regulators have HP and MP ports which are the same size (3/8"). All
Aqua Lung regulators have a high pressure port that is clearly marked "HP",
with a small, restrictive hole that is visible when the port plug is removed. If
your regulator has all 3/8" ports and you cannot determine whether a port is
medium pressure or high pressure, use the following procedure:
1. Connect your submersible pressure gauge, via its high pressure hose,
to the port in question. If your pressure gauge has 7/16" threads, you will
need a 7/16" female to 3/8" male adapter (P/N 101785). Check to ensure
that a second stage is connected, and all other ports are sealed.
2. Attach the regulator to a fully charged cylinder and open the cylinde
3. Take a pressure reading. If the gauge is connected to a medium pressure
port, it will indicate less than 200 psi.
