This 40+ year old regulator recently came into the shop for service. A rare Poseidon Odin first stage with a 4300 psi rated yoke! The second stage is a Jetstream 2nd stage currently still being sold by Poseidon & used by United States special forces & discerning divers the world over. Ice, deep or contaminated water? Bring it. You want high flow? This system has it & then some. It tuned perfectly & breathes as well or even better than most air delivery systems today.

What are the chances of getting two Independant customers at the same time wanting O2 serviced twin steel 72 cu. ft. cylinders & manifolds, powdercoated white & filled with Nitrox? Not all steel 72’s are alike, some made by Pressed steel tank, Norris to name a couple so there are slight subtle shapes & size differences as you can see in this photo. Why invest good money in these old tanks? 2250 psi rated Steel 72’s were made with a much better steel alloy than newer high pressure cylinders of today, always pass hydro if cared for, can always be filled to capacity, their buoyancy is great and 72’s make an awesome set of double’s. You could say that these doubles are more than worth the trouble’s!

Most are either 3/8″ for L.P. 7/16″for H.P. & 1/2″ for the classics on older U.S. Divers and duty built Dacor. Mostly chrome plated brass but there are Titanium & Aluminum as well. Some same sized port plugs take different size O-rings, have different O-ring lands & overall differing depths! Use caution mixing & matching between manufacturers. This photo represents longevity, we know not many Dive Centers can produce a supply quite like this!

Fills up a Home Depot bucket & weighs almost 10 lbs! Coastal divers having a hard time so far. Offshore divers doing better with some doing way better than most. This one is from off of Palos Verdes. Openwater Habitat & a select group of Cats will be featuring on this tonight!

Filling compressed gas cylinders is a serious matter. The Federal Government says that it’s illegal to fill gas cylinders beyond their rated fill pressures. Injuries at the fill station are common. Gas cylinder filling is a Hazmat situation that requires training for any individual who provides pressurized gas fills. Many divers want a “good fill” but what is a good fill? Divers seem to want their cylinders overpressurized meaning more than the cylinder is rated for. Cylinders are engineered & tested to allow for their maximum fill pressures. When cylinders get taken above their engineered max fill pressure things can go wrong. Cylinders will begin to weaken & potentially they will fail their hydrostatic test. It compromises the bust disc causing the burst disc to get bulged & then the burst disc can let go well below its rated burst pressure & at any given time (even U/W!) Most of our more discerning divers bring their cylinders in to fill well in advance so as to allow us to fill nice & slow, allow for cooling then to top up to the final psi while cooled.

We warned you in this post a year ago about miflex hoses. Now DAN (Divers Alert Network) posted a additional issue with these hoses. They allow for polymorphic crystallization corrosion on the inside constricting & potentially blocking the air flow. Cyclical heating & cooling at oil-water interfaces combined with the molecular structure of the internal tube lining promotes crystallization of these materials allowing growth to accumulate over time & that is just what’s happening inside! The external fiber woven sheath acts like a cheese grater. The hose sheath fibers collect sand, soils & vegetation. These hoses fray & the plastic sheath fibers stick out & can stab you! What is wrong with rubber? They are stronger, last longer, flex as much & cost less.
