Frequency-tunable bracketless fluid manifold

A fluid manifold apparatus includes: (a) an array of spaced-apart manifold fittings (34), each manifold fitting (34) aligned in a predetermined angular orientation. Each manifold fitting (34) includes: (i) a tubular neck (38); (ii) a pair of spaced-apart tubular arms (40) extending away from a first end of the neck (38); and (iii) a coupling (42) connected to a second end of the neck (38); and (b) a plurality of curved tubes (36), each tube (36) being coupled to one arm of each of two adjacent manifold fittings (34).
