K-Style 45-Degree Oral and Power Inflator Incorporating the Common Shrader Valve BC Quick Disconnect Post Includes a Removable Rubber Mouth Guard and Pull-to-Dump Cable Pin How to Replace a Power Inflator Power Inflator Service
  • A replacement K-style 45-degree Power Inflator
  • Fits 1-inch inside diameter corrugated rubber hose
  • Includes mouth guard and pin for pull-to-dump cable
  • Compatible with many/most Scuba brands
  • The attaching hardware (clamps or zip ties) is not included

The BC quick disconnect post on the DGX Oral Power Inflator is compatible with the slide-lock Schrader Valve fitting found on most ordinary low pressure BC inflator hoses. This widely used power inflator fits the 1-inch inside diameter corrugated rubber hose found on most tek BC aircells including those from Dive Rite, Halcyon, Highland, HOG, Hollis, IST Dolphin, Light Monkey, OMS, OxyCheq, White Arrow and many other brands.

Includes a removable rubber mouth guard and the pin for a pull-to-dump cable.

Push the button on the end to deflate or orally inflate the BC via the mouthpiece; push the other button for power inflation via the low pressure BC hose. Push both buttons simultaneously to dump gas out the mouthpiece directly from the low-pressure hose, a neat trick allowing you to leave your second stage in your mouth while still inflating a lift bag or SMB.

This product does not include attaching hardware (ie. zip ties or clamps that secure the product to your corrugated hose.)The attaching hardware is available separately.

Some inflation assemblies have a cable that runs through the inside of the corrugated hose. This cable is attached to the power inflator using the pin, such that if you pull down on the inflator itself (and thus pull the cable), a dump valve at the top of the inflator assembly is activated. This feature is usually called 'pull-to-dump' or 'remote-exhaust.' Your inflation assembly may or may not have the feature and the cable, but we include a replacement pin just in case you do need one. If the pin turns out to be unneeded you may safely discard it.

Quick-Disconnect Compatibility and Lack Thereof

Divers are sometimes surprised to learn there is NO universal standard that defines the precise shape and exact dimensions of the common Schrader valve quick-disconnect ( QD ) fittings found on power inflators and low-pressure inflation hoses used in SCUBA. This can cause compatibility issues with the connection: the fittings will not securely connect and can self-disconnect without any overt user action; the fittings will securely connect but gas will not flow; the fittings will connect but will exhibit slow leaks. There is the further complication that the common Schrader valve QD fittings are not suitable for high-flow, so QD fittings found on BC integrated second-stages use something else entirely.

The Schrader male posts can be broadly divided in to two categories: a more widely seen post with a shorter barrel and a raised bridge across the top, or a much less common post with a slightly longer barrel and a flat top. In our experience, the flat top post seems more likely to be encountered in the UK and to a lesser extent in Europe; it's almost never seen in North America or Asia. Hoses designed to fit one category of post are less likely to be compatible with the other. However, even within the bridge top post design we have encountered occasional incompatibilities, usually when there is many years difference in age between the male and female fittings. We have seen problems caused by the Schrader valve core becoming partially unseated (or not properly seated during initial assembly) inside the female hose fitting; that's corrected by using a Schrader Valve Tool to tighten the core back in place. We've also seen slow leaks resolved by replacing the worn 011 O-ring located inside the barrel of the female hose fitting, although replacing that O-ring in the QD is challenging to do without a QD O-ring insertion tool and most consumers just replace the entire hose.

The good news is these incompatibilities are very rare; all the low-pressure BC hoses we sell are compatible with the Schrader valve post found on our replacement power inflator as well as the inflators on all the wings we sell. If you are concerned about compatibility, the best strategy might be to replace the power inflator and hose simultaneously from the same source. Keep in mind that if your BC hose is more than five years old, best practice is to replace it anyway.
