  1. What Happened to My Gas? 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 ...
  2. Common Uses for Stainless Steel Snaps How to Attach a Snap
  3. StainLESS does not mean StainPROOF 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, ...
  4. Perfect Positioning of Decals 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, ...
  5. Stage Straps 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 ...
  6. A Gas Booster Reality Check 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 ...
  7. Installing Valves in SCUBA Cylinders 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 ...
  8. What is the difference between "200 Bar" and "300 Bar" fittings? 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 ...
  9. Threading a 3-Slot Quick-Release Belt Buckle 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 ...
  10. Calibrating Oxygen Analyzers for Diving 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 ...
