Inflator Service Tool w/O-Ring Kit
Inflator Service Tool w/O-Ring Kit
- Disassemble and service your Power Inflator with this complete kit
- Tool has three openings that are compatible with most tek BC aircells
- Includes a complete set of oxygen compatible replacement O-rings
- Watch the video above for exact instructions BEFORE you perform service
- NOT compatible with Aqualung, Cressi, Genesis, Mares, Oceanic, and ScubaPro
The stainless steel Inflator Service Tool has three openings that allow easy disassembly of the widely used generic power inflators found on most tek BC aircells including those from Dive Rite, Halcyon, Highland, HOG, Hollis, IST Dolphin, Light Monkey, OMS, OxyCheq, White Arrow and others. The tool will NOT work for proprietary inflators as found on Aqualung, Cressi, Genesis, Mares, Oceanic, and ScubaPro; those inflators are not user serviceable. The tool includes a complete set of replacement oxygen compatible O-rings.
- 1/2" hex wrench for the low pressure quick release nipple
- Special spanner with two bent tangs which fit the slots in the inlet valve cartridge assembly and facilitates its easy removal
- 3/8" hex to keep the end of the valve spool in place while removing the plastic button from the cartridge valve assembly
- Handwheel nut driver used to service scuba valves.
- Includes the five O-rings found in the power inflation mechanism: 112-V90B, 012-V90B, 011-V90B, and two 006-V75B.
The manual exhaust is not pressurized and operates independently of the power inflation mechanism. On some designs it requires an uncommon deep well socket tool for disassembly. The manual exhaust contains an additional O-ring that we've never seen fail. We don't recommend disassembling the manual exhaust assembly, and so we don't include the manual exhaust O-ring in the kit.
The power inflator service tool, o-ring kit and overhaul instructions are a 'save-a-dive' solution for qualified professionals but our recommendation is to replace, not service, your power inflator if it develops any problems. Improper service could cause a failure of buoyancy control, which has serious and life threatening consequences.
How to Overhaul a Power Inflator
If the base of the inflator QD fitting is leaking, use the 1/2" hex to remove the fitting and replace the o-ring. However, look closely if you see a leak. Sometimes the leak is not coming from the base of the fitting, but rather from the connection to the hose. There is a small o-ring in the female end of the hose fitting that is more frequently the source of the leak.
If the inflator is dribbling gas into the BC, we recommend replacing the entire assembly. However, if you wish to overhaul the inflator start by mating the spanner tangs to the two slots of the inlet valve cartridge assembly, then unscrew counter clockwise until the entire assembly can be removed.
Now disassemble the cartridge assembly. Depending on the design of the assembly, wse either a flat blade screw driver or the hex to keep the end of the spool from turning while you unscrew the plastic button. Once the button separates from the spool, push the spool out from cartridge barrel. Remove all the o-rings (noting their relative positions and sizes) and clean everything, including the inside of the barrel and the plastic body of the inflator, by briefly soaking in a 50/50 solution of white vinegar and water. If need be, scrub with a light application of a toothbrush but don't use an ultrasonic cleaner.
Replace the o-rings and reassemble. The o-rings must be clean and need not be lubricated. Some people lubricate the small 006 o-rings to provide a smoother operating feel, but we observe they are not lubricated at the factory in new inflators. (We do not lubricate because we think it attracts dirt and just gums up the works so that it has to be more frequently cleaned.) Tighten until snug, but do not over tighten or you will crack the plastic body. If the inflator still leaks or begins to leak within a few dives, then the surfaces which the o-rings seal against are worn and the entire inflator assembly should be replaced.
The manual exhaust is not pressurized and operates independently of the power inflation mechanism. The manual exhaust contains an additional O-ring that we've never seen fail. We don't recommend disassembling the manual exhaust assembly, and so we don't include the manual exhaust O-ring in our kit.
