Industrial JS45719 Compressed Gas Regulator

Pre-owned Aldrich® non-corrosive lecture-bottle gas regulator (JS45719) delivering 0–100 psig from cylinder pressures up to 3,000 psi. This single-stage regulator uses a CGA 170 inlet and a 1/4" male NPT outlet, all housed in a compact chrome-plated brass body designed for laboratory use. Operating temperature range is -40 to 140°F (-40 to 60°C). The unit includes a PTFE sealing washer for leak-tight cylinder connections, with spare PTFE washers available separately. Specifically intended for lecture-bottle gas regulation, it provides a stable, low-pressure gas delivery suitable for calibration, analytical setups, and bench-top experiments that require precise control from high-pressure cylinders.
