Plain Elbow Inflation Assemblies
Plain Elbow Inflation Assemblies
- Complete corrugated hose assembly with a "plain elbow" at the top
- Ideal for diving in overhead environments - eliminates a "failure" point
- Choose from two different hose lengths - 16" is most common length
- Compatible with all Dive Rite, Oxycheq and DGX brand wings
- NOTE: The Bladder Flange Gasket is NOT included
Most single tank air cells come standard with a low-pressure hose, oral/power inflator, corrugated hose, and depending on the model either a remote exhaust elbow dump valve or a plain elbow. Most double tank air cells come standard with a low-pressure hose, oral/power inflator, corrugated hose, and a plain non-exhaust elbow. This design is preferred by technical, cave and wreck divers because of the reduction of the "failure" point found on common Remote Exhaust (Pull-to-Dump) assemblies.
Compatible with all Dive Rite, Oxycheq and DGX Gears (and some others) brand aircells. Not compatible with SeaQuest, Scubapro, Mares, Hollis, Halcyon, Zeagle, OMS, Aqualung and some other major brands.
NOTE: The Bladder Flange Gasket is NOT included.
NOTE: The length descriptions are for the corrugated hose only including the hose cuffs, not an entire assembly, and measurements are APPROXIMATE. Because the corrugated hose can stretch over time and with use, the length will change.
Many technical diving companies have, for years, used a corrugated hose made with an EPDM rubber blend raw material that has been used in diving applications for decades with excellent performance in the field. The material includes a surfactant that exhibits a gradual "blooming" of a white haze on the surface of the hose as it dries over time following manufacturing. The bloom is purely cosmetic and although harmless, if you wish, it can easily be scrubbed off with soap, water, and a cloth.

Replacing Air Cell Inflation Assembly Elbows
Removing and replacing an air cell elbow must be done correctly; otherwise damage may result. The most important thing to remember is to turn only the collar at the base of the hose elbow, and not the elbow itself. Turning the elbow results in either loosening or damaging the flanges that mate the elbow to the air cell bladder. The video illustrates using a tool to turn the collar, but frankly the best tool to use is simply to turn the collar by hand.
When installing or reinstalling the elbow, make certain the gasket is centered in place between the elbow flange and bladder flange. As you tighten the collar, avoid cross threading by first turning counterclockwise until you hear a click. As you begin turning the collar clockwise, you will feel the elbow seat into the flange and lock into one of several possible positions. If the elbow assumes the wrong position, loosen the collar, reorient the elbow and begin again.
After tightening the collar as far as it will go, fully inflate the air cell and check for leaks. The air cell should be able to remain fully inflated for several minutes without exhibiting any substantial air loss. You may find the gasket has compressed after a few days and you will need to snug up the collar again, tightening one eighth to one quarter turn by hand.
