Inflatable door seals

[Glen Davis]

In my former aircraft, I had an inflatable door seal, made by Bob fields. It worked great and keeping the draft out and the cabin quiet. It had a round rubber pump. You squeezed by hand a number of times which pumped up the seal. It also had a metal knob on the hand pump which you opened to deflate the seal. My new airplane appears also to have an inflatable door seal. But there are two rubber hand pumps, one underneath each of the two front seats.   Is anybody familiar with this product and why two pumps instead of one.   Incidentally, they do not appear to be working as the seal on the door does not inflate, but that might be just from a break in the tubing somewhere that I haven’t found.

Those bulbs are for lumbar support bladders in the front seats.
