Stainless Steel Braided HP Hose is an extreme-duty SCUBA hose perfect for high-impact high-stress applications such as sidemount diving and stage bottles. They are also a good option for dive computer transmitters. Available in two lengths with an outside diameter of 12.4 mm, many experienced divers prefer to use the { 9 in | 23 cm } length hose when it will be folded and tied back or the [ 6 in | 15 cm } length when it will remain straight.

The hoses have a standard 7/16-inch male at the end that screws into the first stage HP port and a standard 7/16-inch female swivel at the end that screws on to the SPG or transmitter. The hoses have chromed brass fittings and are designed to conform to the EN 250:2014 standard with a maximum working pressure of {5500 psi | 380 bar} and a burst pressure rating of {16,500 PSI | 1137 BAR}. The hoses are Nitrox Ready.

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 or transmitter. 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.

Tek Tip Warning Image WARNING

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.

Rigging the SPG on Stage and Sidemount Bottles

SPG Rigging Examples

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.

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.
