Compact Manual Inflator by United Moulders

The United Moulders Compact Manual Inflator, also known as the Mini Manual, is a simple but effective manual inflator commonly found in lifejackets.

You can find the link to the rearming kit or the individual parts used in the United Moulders Compact Manual Inflator here.

When you buy the rearming kit, RTS includes an information sheet which will help you rearm your lifejacket and give you some additional advise which you may find useful. But below are a few key points for you to consider.

DO NOT TRY TO SCREW THE CO2 CYLINDER IN FIRST!!! The firing pin may still be raised and the Cylinder will fire in your hand and could be very uncomfortable.

The first thing you have to consider with this device is the side retaining clip.

The Clip is part indicator, in that if you see the clip in place, green means good. If the clip is missing, you only see red which means warning, the device needs checking and assessing.

The Clip also serves a practical purpose. The clip provides some resistance so a proper tug is required to inflate your jacket, reducing the occurrence of accidental inflations caused by the manual toggle catching on something, or the arm working lose and raising the firing pin.

Next step is to check your Cylinder Gasket.

It should be sitting centrally inside the inflator Op Head. When you pull the toggle, the firing pin comes up through the hole in the middle of the Gasket and pierces the CO2 cylinder. The gasket has a dual function. It prevents CO2 escaping through the threaded area. It also creates a reverse pressure against the thread, meaning that the cylinder is less likely to work lose in wear.

Your RTS Compact Manual Inflator rearming kit comes with a Cylinder Gasket, which you only need to use if worn or missing.

Finally you can screw in your CO2 Cylinder.

The Cylinder should be screwed in fairly tight.

With the United Moulders Compact Manual Inflator you do not have to worry about expiry dates of inflator parts.

CO2 Cylinders are engraved with a manufacture date but do not have an expiry date.

CO2 Cylinders only need to be replaced if the gas has been used or escaped, or if there are signs of damage such as rust.

Similarly the clip can last a long time and only needs replacing if worn, broken or missing.

It is always handy to have a spare clip and cylinder though, so that in the event of an inflation, the jacket can be put back in service quickly.
