Threaded In-Line Flame Arrestor

Threaded In-Line Flame Arrestor

Model L76T-UF

Threaded In-Line Flame Arrestor

The L76T-UF model is designed to inhibit flame propagation in gas piping systems and to protect low pressure tanks containing flammable liquids. Arrestors protect low flash point liquids from external sources of ignition. This provides increased fire protection and safety.
