Description

This row is held. Its name is a measurement, and the measurement is the part that cannot be sourced. 16/22 mm is a genuine convention in aquarium plumbing, used by several canister filter manufacturers for inner and outer diameter, and hoses and fittings sold under those numbers do generally fit one another. What does not appear to exist, as far as this catalog has been able to establish, is a standards body that publishes it. There is no ISO or DIN reference to point at, only an agreement between manufacturers that a catalog can describe but cannot cite. That distinction matters more here than it would on a page about a substance or a procedure. A hose row has no chemistry, no dosage and no biological effect. Its entire content is the number in its own name, so a citation establishing merely that aquarium hoses exist would leave the actual claim exactly as unsupported as it is now. This catalog has deleted rows for less, and this one is kept only because canister plumbing is a real thing that keepers really search for. The related warning is worth stating plainly, without pretending it has a source behind it. Nominal sizes drift between brands, and a hose sold as 16/22 does not always seat properly on a tap sold as 16/22 by a different manufacturer. Measure the barb you already own before ordering to a label. The row graduates when a published standard, or a manufacturer specification this catalog can actually open, is available to cite.
