For vacuum applications where space is at a premium, Beswick Engineering (Greenland, NH) is rolling out an ultra-miniature, single-stage vacuum regulator. The vacuum regulator controls output from 0 psig to full vacuum, and is said to be especially well-suited to low-vacuum applications. The lightweight component is designed to be mounted in line, and does not require panel mounting. Weighing just 30 gm apiece, the brass and steel regulators are a scant 35/64 of an inch high.
