I have several, so a straight transfill gets me pretty close to the large cylinder supply pressure. If I need to go higher, I seek the services of a dive shop with a booster pump, but then you pay dive shop prices for oxygen.</p>

Probably dependent on
the manufacturer and retailer, the latter usually supplying newly purchased cylinders with an initial visual inspection sticker for recreational divers. With the prevalence of nitrox mixtures in recreational diving, it is becoming more commonplace to supply conformant cylinders, but check with your supplier. Oxygen cleaning is something you can do yourself, simply by using hydrocarbon free detergents, rebuild kits or o-rings which are O2 compatible (i.e. Viton), and O2 compatible lubricants such as Christolube.</p>
