TX-2L with Pressure Relief Cap and 3/4″ female pipe threads on both ends. The body is made from cast aluminum and has a 11.0 fluid ounce reservoir. Maximum working pressure is 300 psi., and maximum air flow is 70 CFM at 90 psi.
The Pressure Relief Cap allows the operator to depressurize the reservoir after the lubricator has been disconnected from the air line. Depressurization is necessary to keep the oil in the reservoir from continually flowing when not in use.
