Replacement Gas Cartridges For Ansul Model 20 Red Line Extinguishers

These are replacement gas cartridges for the Ansul Red Line Model 20 series of field-refillable cartridge extinguishers.  Choose from CO₂ (left hand thread only) or nitrogen (left or right-hand thread). These items are non-returnable. As they ship directly from Ansul, they are subject to minimum order requirements so we can not fill orders for just one or two cartridges.

Right-handed (reverse threaded) nitrogen cartridges are used in low-temperature extinguisher models; the remaining models use a left-hand thread. Most of the non-low T models use a CO₂ cartridge, but some specialty units use left-hand nitrogen cartridges. It is critically important that you check your extinguisher nameplate label and owners manual before ordering and installing the cartridges.
