Missing a dive because of lost gas is a very annoying experience, and
it's often blamed on a short fill. The more likely reason is a gas leak
caused by carrying a cylinder with the handwheel and allowing the valve
to be inadvertently opened slightly. This typically occurs when the ...
A common misconception among divers is that stainless steel does not corrode at all. There are various types of stainless steel, each with different corrosion properties, that make a specific grade more or less suited to a particular application. Because there is no perfect stainless steel, ...
Clean the surface of the cylinder to remove any deposits and old
decals. On painted aluminum cylinders we recommend scraping any
blistering or peeling areas to remove loose paint. Most adhesive
remnants are easily and safely removed with Goo Gone.
If you use any cleaning solvent, ...
Cylinder straps (aka stage straps) provide an efficient means
of using bolt snaps to attach the cylinder to your harness hard points
(D-rings or sidemount rails). In some designs the strap may also be
used to help carry the cylinder. The strap itself is a piece of round
cord or flat ...
Comparing various specifications published for gas boosters,
including the one we sell, can be misleading. The manufacturer
published specifications are often the ideal maximums and minimums. Do
not expect any booster to deliver the ideal values, although a top quality
booster can come ...
Before installing the valve, any existing lubricant should be completely removed from both the cylinder threads and the valve threads using a clean lint-free cloth. Always place a new neck o-ring at the base of the valve inlet threads (an oxygen compatible neck o-ring is always included with ...
The two designs are nearly identical, but the 300 bar valve outlet is
deliberately deeper so the shorter 200 bar connector will not be long
enough to seat properly. This is a safety feature to prevent connecting
a low pressure device to a high pressure supply, but it works perfectly ...
For harness and weight belt applications, we recommend only using a three-slot metal buckle with a pinned hinge mechanism that is riveted. We also suggest using a design that has a positive detent on the closure. The webbing should be woven through all three slots and then back upon itself ...
Analyzing oxygen requires the analyzer first be calibrated and that calibration requires a "known" gas. The gas most often used for calibration is Air, commonly described as 20.95% Oxygen. However, it's really not always 21%, in fact the Compressed Gas Association says Air can contain from ...
