Dave and Paul, thanks for the compliments.

One can most likely see the welds looking into the exhale opening with the proper light. Perhaps with an inspection mirror and small LED?

I pondered using some sealant but decided it would be best to have it welded. Remember the compartment wall can possibly move a little when the sorb is compressed. Good tip about the sealant Dave! I know there are a million speciality glues/sealants never heard of by the average consumer. Just make sure its compatible with very high pH (normally not a big issue)

A friend of mine had a nasty small hole in the soldering in the top of an IDA-76 scrubber between the two compartments effectively making a small bypass. If I recall correctly it took a small inspection mirror and light to see it. Anyway it was sealed by the use of a long syringe and some sealant (don't remember the make).
