DGX Custom - SPG Assembly with SHORT HP Hose

LOOK CLOSELY! A common mistake is ordering the wrong SPG, especially PSI or BAR. Because of the special considerations for very short HP hoses, we recommend the {9 in | 23 mm} braided Stainless Steel as the best choice for durability and reliability.

These short length high-pressure hoses are popular for use with deco, stage and sidemount applications. Order our premium quality naked SPG with spool that includes Nitrox Ready o-rings, and our premium quality short high pressure hose with everything configured exactly as you want and we will assemble it for you.

Regardless of brand, material or quality the very short high pressure hoses seem to prematurely develop "fizzing" leaks at the fitting swages sooner than the much longer HP hoses typically seen on backmount configurations. We suspect there are two reasons for these premature failures: First, the short hoses are often being folded back on themselves in deco, stage, and sidemount applications. Second, the very short length does not provide any cushion to the impact of pressurization as a result of rapidly opening the cylinder valve. See our TekTip below for our recommendations on rigging the SPG with very a short hose, and while valves should always be opened slowly on SCUBA cylinders this is especially critical when the first stage is rigged with a very short HP hose.

Our experience has been the 9-inch length is consistently more reliable than the 6-inch length, regardless of flex or rubber hose construction. Recent availability of the braided stainless steel jacket over an inner nylon tube construction offers improved reliability over the flex and rubber versions. Dive Gear Express now recommends the 9-inch braided stainless steel high-pressure hose for all diving applications that require a short HP hose.
