Description

This row is held rather than finished, and the page says so rather than filling the space. Air line is a real product, and this is not a doubt about whether it exists. The problem is that everything a catalog entry would want to say about it is a specification, and this catalog has verified none of them. The description this row arrived with named a bore of 4/6 mm and a polymer, PVC. Neither has been checked against a product, a manufacturer's datasheet or a standard, and both are the kind of detail that gets copied between listings until it starts to look like a fact. The reference works this catalog cites elsewhere do not reach hardware at this level. The Merck Veterinary Manual mentions flexible tubing exactly once, in a description of a surgical rig that recirculates anaesthetic water over a fish's gills, which is not air line and would not support a claim about one. Citing it here would be the stretch that this catalog's own rule forbids, so no source is claimed and the page stays out of the index. What is safe to say carries no numbers. Air line is sized by inner and outer diameter, and a pump, a check valve and an air stone bought separately only fit each other if those diameters agree. Buy the tubing after you have the fittings rather than before, and take the old piece to the shop if you are matching something already in the tank. The row stays because the product is real. It graduates the day there is a published specification worth citing.
