FLM Injectors are positive displacement grease dispensing valves with high injector outputs and proprietary surface coating. These units can satisfy lubrication needs of medium and large off-road machinery operating in harsh environments. Standard Viton O-rings protect against high heat and synthetic lubricants. FLM Injectors are interchangeable with other commonly used parallel injector systems. Other features include adjustable grease output, vinyl cover caps and a visual operating indicator pin. FLM Injectors include feed line fill fitting in size B only.
