Dive Rite High Pressure Braided Stainless Steel Hose
Dive Rite's Stainless Steel Braided HP Hose is a rugged alternative to traditional rubber and nylon braided HP hoses. Its braided stainless outer sheath protects the inner nylon tube. The Stainless Steel Braided HP Hose is ideal for heavy use applications such as side mount and stage bottles. Dive Rite tells us this hose has proven to be exceptionally reliable.
- Weight: 2.1 ounces (60 grams)
- ID= 3.5mm OD= 8mm
- Working Pressure is 5,000 PSI, Burst Pressure 20,000 PSI
All high-pressure hoses use an 'air spool' with two tiny o-rings to mate the swivel connector on the hose to the fitting on the gauge. With a worn or missing air spool, any HP hose will LEAK at the swivel. The air spool is not included with the hose but we recommend replacing the air spool when replacing the hose.
WARNING
Keep in mind that all hoses will fail sooner or later either due to age, storage conditions or handling. Scuba hoses, regardless of brand and materials, require some minimal care. Do not allow hoses to receive prolonged exposure sunlight, as the heat and UV from strong sunlight will significantly shorten the life of the hose. Do not attempt to flush the inside of the hose with any form of solvent or other chemical, new hoses are factory clean and if you have any reason to think they are no longer clean then the hose should be replaced. Prior to every dive trip you should always pressurize and inspect your hoses for mechanical damage, corroded fittings, bulges and leaks. Dive Gear Express suggests replacing all SCUBA regulator hoses every five years of service or 500 dives, whichever comes first.

Rigging the SPG on Stage and Sidemount Bottles
The classic method technical divers use to rig a stage or sidemount bottle is a compact or "brass & glass" gauge assembled with a very short high-pressure hose folded back on itself against the first stage and permanently tied in place with a piece of cave line. We do NOT recommend doing this with a rubber or flex hose because the hose is also permanently stressed at the two weakest points, the fitting swages. Although not as convenient to read, allow the SPG and hose assembly to lie straight against the tank while held against the side of the cylinder under a hose retainer. Because the short hose is less able to absorb the impact of rapid pressurization, we recommend following best practice to depress and hold the second stage purge while slowly opening the cylinder valve until the regulator begins equalizing with the cylinder pressure.
If you prefer folding the hose, then use a bungee loop (about 1 foot of 3/16" with the ends tied together in a fisherman's knot or we prefer an overhand loop w/pigtail) instead of cave line because when the regulator is off the stage the bungee loop allows the hose to be unfolded. Some divers also prefer using a slightly longer hose when folding, hopefully offering a reduction in stress on the folded hose. Regardless, in our experience all short rubber or flex hoses still may fail prematurely from being folded back on themselves. Recent availability of short high-pressure hoses with a braided stainless steel jacket, together with the bungee loop rigging method, seems to be the most durable and reliable compromise.
Here is one final thought... ask yourself "Do I really need a full size SPG?" Sometimes the exact amount of the gas remaining in an off-board bottle is not being used to control the dive. The only reason for the presence of the SPG on the travel or bailout bottle is the diver just needs an indication of cylinder contents as full, partial, or empty. If your diving application doesn't need an exact reading on gas remaining in the cylinder, an inexpensive button SPG will significantly reduce the number of failure points. This is especially true of bailout bottle applications, whereupon switch to bailout also terminates the dive and knowing the exact tank pressure is unlikely to be meaningful.
