US Divers Non-Magnetic DA AquaMaster Identification
 The US
Divers non-magnetic
AquaMaster regulator was
used by US Navy UDT teams to disarm magnetic mines, so the regulator
had to have very low magnetism. Since chromium has some magnetism, they
did not use chrome plating on this regulator. But they did need
corrosion protection since it was used mostly in salt water. They chose
to gold plate many of the parts including the nozzle (1012-12), the HP
seat (1010-65), the spring block (1000-23), the LP seat holder
(1010-04). and the LP seat retainer (1010-07). These gold plated parts
are clearly marked as to distinguish them from the standard unplated
brass parts. They all have a circular groove around the part to show it
is non-magnetic and gold plated. I also have a filter
(1000-38) that looks like it is gold plated, but it has no
distinguishing marks. Also, as many already know, all non-mag regulators had an
unmachined
hookah port on the regulator body and the entire regulator had a black
oxide anti-glare and corrosion resistant finish. I have seen many
examples of these regulators and most have had many parts switched in
them over the years. Many of them that you find today will have some
chrome and/or brass parts instead of the original
gold plated ones. |
