PortaGreen cylinders offer a reusable, sustainable calibration gas cylinder option as part of a convenient return program. PortaGreen cylinders are more compact, globally approved and can be cross-referenced to any existing manufacturer’s specification. These cylinders also feature PortaGas’s patented regulators which have unique serial numbers traceable to N.I.S.T. (as do the cylinders themselves), knurled on/off knobs for easy grip, and passivated surfaces that prevent gas absorption. Each PortaGreen cylinder comes with a return tube, eliminating the hazmat liability and making it easy and convenient to return the cylinders without any return fees. Simply strip off each layer of perforated shrink wrap and return via FedEx in the tube provided. No paperwork, no packing, no valve to crush, no hole to drill. Just strip and ship!
